Influencer Change Monitor

📈 What can Influencer Change Monitor do?

A saved creator list in, changes since the last run out. One row per change: a follower milestone crossed (1K, 5K, 10K, 25K, 50K, 100K, 250K, 500K, 1M and up, in either direction), a newsletter added, a new product (a sells flag turned true), a new bio link, a new manager. An unchanged creator gets no row of its own. A run where no creator changed returns exactly one no_change row: the list name in change_from, the count of handles checked in change_to, and the run time in read_at. That row charges nothing. On every other run the row count is the change count. The first run for a list returns one first_seen row per creator, the baseline later runs diff against.

State lives in a named key value store on your account (creator-change-monitor-state, one key per list_name), so a run with the same list_name and handles next week compares against this week.

Bought by newsletter and creator tool companies watching a target list for the moment a creator adds a newsletter or a product, brand partnership teams tracking milestones, and talent teams watching for a new manager.

🚫 This is not a profile scraper. An unchanged creator gets no row, so a run's row count is its change count; a run with no change at all returns one uncharged no_change row instead of an empty dataset. To read a list once, use the Influencer Profile Scraper; to watch it week over week, use this.

🧭 One route per platform, measured before the price was set

Five public profiles per platform, read at 1, 2, 3, and 5 in flight. USD per profile is transfer at the account's datacenter rate ($0.20 per GB) or residential rate ($8.00 per GB) plus an estimated compute share (1 GB, wall seconds over 3,600, at $0.30 per compute unit). The default concurrency sits below the point where rows started dropping, or two below the largest wave tested when nothing dropped.

Platform	Route	Fields returned	Per profile	Ok of 5 at 1, 2, 3, 5	Default concurrency
TikTok	Profile page rehydration JSON over datacenter; one residential retry on a block	name, followers (exact from statsV2), following, video count, engagement (lifetime likes per video over followers), verified, bio, bio link, business email from the bio	372 KB, 1.5 to 3.0 s, $0.00007 (a residential recovery costs $0.0030)	5, 5, 5, 5 minus one block per wave at 5	3
Instagram	Profile embed widget over datacenter (counts, name, verified, 6 recent posts); bio, bio link, and following from web_profile_info on about 1 in 4 datacenter attempts, otherwise from the profile page over residential when escalate_on_block is on (event instagram-bio-fetch, $0.010, only when that page came back readable)	name, followers (exact), post count, verified, private flag, engagement (median likes plus comments of recent posts over followers), bio, bio link, business email from the bio	embed 303 KB and $0.00006; residential bio page 720 to 830 KB, up to $0.0066 by decompressed bytes and $0.0012 by the platform's metered transfer (run o6u6d7x7zfElI9WQm, 2026-09-22); the residential page ran on 7 of 10 reads on 2026-09-22 and read on 6	5, 5, 5, 5	4
YouTube	/@handle/about page ytInitialData over datacenter; innertube fallback; residential only after every datacenter route blocks	name, subscribers (rounded by YouTube), video count, description, channel links, country (platform region), verified, engagement (average recent views over subscribers)	2.2 MB, 2.0 s, $0.0005	5, 5, 5, 5	3
Threads	Public profile page Relay payload over datacenter; residential only on a block signature	name, followers (exact), bio, bio link, verified, business email from the bio	0.93 MB, 5.0 s, $0.0003	5, 5, 5, 5	3
Pinterest	Profile page __PWS_INITIAL_PROPS__ over datacenter; residential retry on a real block	name, followers, following, pin count, verified merchant, about, website, location, business email, other social profiles	1.39 MB, 1.8 to 3.0 s, $0.0003	5, 5, 5, 5	3
Twitch	Public GQL endpoint with the site's own web client id over datacenter; channel page JSON-LD fallback; your own Helix client id and app token when supplied	display name, followers, video count, partner flag, description, social links from the channel panels, business email in the description	1.2 KB, 1.2 to 1.6 s, under $0.00001	5, 5, 5, 5	3
Podcast	iTunes lookup plus the RSS feed, direct (no proxy bytes); Spotify show page over datacenter	show name, episode count, description, site link, owner email from the feed (business_email_source feed), author, genres, country	feed 0.5 to 5.4 MB direct, compute only, 0.8 to 2.9 s	5, 5, 5, 5	3

Discovery per keyword, measured the same day: TikTok 7 handles over three Google pages (Google drops the site: operator on some exit countries, so a page without a handle is fetched once more); Instagram 1 to 8; YouTube 20 from the channel filtered results page with no search engine; Threads 11 to 15 over two Google pages; Twitch 11 from its own search; Pinterest 50 from its user search resource; podcasts 50 from the iTunes Search API. A Google page costs $0.0025 on the runner's account.

What each platform does not expose without login, and what the row says instead: YouTube's business email sits behind "View email address" and a verification step, so it is not read and business_email is filled only from an address written in the public description; Instagram has no location field, so country_guess comes from the bio; Threads and podcasts have no per post engagement; podcasts have no follower count; TikTok's anonymous render carries no region, so the country comes from the bio.

📋 What data can Influencer Change Monitor extract?

59 fields per row, the same 59 in the same order on every actor in this suite. The ones this actor fills:

Field	What it holds
change_type	follower_milestone, newsletter_added, new_product, new_bio_link, new_manager, first_seen, or no_change (one uncharged row when a run finds no change: change_from is the list name, change_to the count of handles checked, read_at the run time)
change_from, change_to	The previous and the current value
previous_run_at	When the previous snapshot was taken
platform, handle, profile_url, display_name, followers, bio_link	The current profile columns, so the row stands on its own
newsletter_status, newsletter_platform, sells_*, manager_email, own_website, website_is_host_page	The link page columns. website_is_host_page is true when the only site found is a page on a hosting platform (see the Link in Bio Scraper and Newsletter Detector README). Current when check_links is on; carried forward from the last run that read them when it is off
source_url, read_at, row_status, error_reason, billable_events_json	Where the row came from, when, whether it is usable, and what it cost

⚠️ false and null are not the same thing, and an empty cell is not a failed read. A column this actor does not own is null, never missing. On a boolean, false means the page was read and the signal was not there; null means nothing read it. On an Influencer Profile Scraper row, verified: false is a profile without the mark and verified: null is a profile that could not be read. Read row_status before any other column; the paragraph below says how.

Every actor in this suite writes the same 59 flat columns, in the same order, and fills the ones it owns. A column an actor does not own is null, never missing. Nested data lives only in columns ending _json, as a JSON string, so a Clay column reads one cell.

Group	Columns	Filled by
Identity	creator_id, creator_id_method, creator_id_confidence, platform, handle, profile_url, display_name	Influencer Finder, Influencer Profile Scraper
Discovery	search_keyword, niche, similar_creators, similar_creators_method	Influencer Finder; search_keyword and niche also carried over by the Influencer Profile Scraper, Link in Bio Scraper and Newsletter Detector, and Influencer Change Monitor when an input item names them
Profile	followers, following, post_count, engagement_rate, engagement_method, verified, bio, bio_link, location_text, country_guess, country_guess_method	Influencer Profile Scraper
Contact	business_email, business_email_source, website_email, website_email_source_url, manager_name, manager_email, manager_source_url, agency_name, agency_domain, agency_match_method	Influencer Profile Scraper, Link in Bio Scraper and Newsletter Detector, Influencer Talent Agency Lookup
Links	link_in_bio_platform, outbound_links_json, other_social_profiles_json, own_website, website_is_host_page	Link in Bio Scraper and Newsletter Detector; other_social_profiles_json also by the Influencer Profile Scraper
Newsletter	newsletter_status, newsletter_platform, newsletter_url, newsletter_evidence_url, newsletter_check_method	Link in Bio Scraper and Newsletter Detector
Sells	sells_course, sells_coaching, sells_digital_product, sells_merch, sells_membership, brand_deals_visible, discount_codes_visible	Link in Bio Scraper and Newsletter Detector
Change	change_type, change_from, change_to, previous_run_at	Influencer Change Monitor
Segment	segment_tier	Link in Bio Scraper and Newsletter Detector
Run	source_url, read_at, row_status, error_reason, billable_events_json	All six

The Influencer Lead List Builder runs the Influencer Finder, the Influencer Profile Scraper, and the Link in Bio Scraper and Newsletter Detector in one run and fills what they fill. The Influencer Change Monitor and the Influencer Talent Agency Lookup read the profile (and the Influencer Change Monitor reads the link page too when check_links is on), so their rows carry the identity, profile, contact, and link columns as well.

Read row_status first. ok is a normal row. error carries the reason in error_reason (not_found: user banned, private, blocked: bot detection page) and charges nothing. partial means the page was read but a step after it failed, and the reason says which.

The creator ID. creator_id is cr_ plus 16 hex characters of the SHA-1 of platform:handle of the creator's primary profile, so the same creator gets the same ID in every actor and every run. When one run sees the same creator on two platforms, the rows share the ID and each row says how it was linked: bio_link_match (0.9, one profile links to the other), website_match (0.8, same own website), handle_match (0.5, same handle on two platforms, which collides on common words). A lone row is seed_handle at 1.

Country scope. This actor applies no country filter. Every row carries country_guess and country_guess_method from the profile read (the platform's region field, the location text, the bio, or a flag emoji), and no creator is dropped for its country.

🛠️ How to track changes on a creator list

1. Open the Input tab and give the list a list_name. The name is the key the saved state lives under.
2. Put the creators in handles, one per line, with platforms for any bare @handle.
3. Leave check_links on to recheck the link page for newsletter, products, and manager; turn it off for followers and bio link only, at lower cost. The link columns then carry forward from the last run that read them.
4. Click Start. The first run returns one first_seen row per creator, the baseline.
5. Run it again next week with the same list_name and handles. Only the changes come back.
6. Export from the Output tab, or pull the rows through the API.

🧪 Using it in Clay

Add an Enrichment > Apify column, pick this actor, and map your handle column to handles with a fixed list_name per table. Every input is accepted as a string, which is what Clay sends. Schedule the run weekly; a change row lands in the table only when something moved, so the column doubles as a signal feed.

📚 Batch or single

One handle is one run; a list is a batch. Both shapes reach the same code path, and so does the shape the platform produces when Clay sends a top level array against an object schema. Input is deduplicated before any fetch. Rows are pushed as each wave finishes, so a run that hits its timeout keeps every row it already resolved. A row that throws becomes an error row with the reason and the run continues.

Concurrency (batch_size) defaults to the measured per platform value in the table above. Above the measured point results start dropping; that is why the default is not higher.

💵 How much does it cost to monitor a creator list?

Pay per event. Every run is charged one actor-start event ($0.002) to cover the run overhead; every other event is charged for output, never for input. The run stops at the maximum cost per run you set in Apify, or at max_charge_usd, whichever comes first: it delivers every row already charged and charges nothing more.

Event	Fires when	Price
actor-start	Once per run, on start.	$0.002
creator-rechecked	Once per creator read on a monitor run, changed or not. The base price per creator.	$0.008
change-detected	Once per change row, on top of the recheck. A first_seen baseline row is a change row.	$0.010
instagram-bio-fetch	Once per Instagram profile row when the bio, bio link, and following were not on the embed widget or the datacenter API and the profile page was read over the residential proxy and came back readable. Only when escalate_on_block is on; uncheck it to avoid the charge and accept empty bio fields on about half of Instagram rows. Never on the embed or datacenter reads, never on another platform, never on a blocked page, never on an error row.	$0.010

Free Apify plan users get 45 results per calendar month, reset monthly. Upgrade to any paid Apify plan for unlimited use: https://apify.com/pricing?fpr=mamba

💳 What you are billed for. A weekly recheck of 100 creators with 10 changes is $0.80 plus $0.10. The recheck is charged because the work is the recheck, not the result. A run with no change returns one no_change row, and that row charges no change-detected; the rechecks on that run are still charged.

An Instagram creator whose bio needs the residential page on a recheck is charged instagram-bio-fetch on top of the recheck.

Apify bills its own platform usage on top of the event prices.

⌨️ Input

Everything is on the Input tab. The options worth explaining:

Field	What it does
list_name	Names the saved state. Letters, digits, dot, dash, underscore. Defaults to default, so two tasks on one Apify account that both leave it empty share one saved state; give each list its own name.
handles, platforms	The creators to track, same shapes as the Influencer Profile Scraper.
check_links	On by default: rechecks the link-in-bio page every run for newsletter, products, and manager. Off: followers and bio link only, at lower cost, and the link columns carry forward from the last run that read them.
match_agencies	Manager email domain against the agency list.
escalate_on_block	On by default. A profile fetch that returns a bot detection page is retried once over the residential proxy, and on Instagram the bio page is fetched over residential when the datacenter API does not answer; a readable page charges instagram-bio-fetch ($0.010) on top of the recheck. Off: no instagram-bio-fetch is ever charged, and the Instagram bio and bio link stay empty on about half of the rows, so a bio link change on those creators is not seen.
max_charge_usd	Optional. Your own cap for this run, in USD. The run stops before any charge that would take it past this amount, delivers every row already charged, and drops the rest. Leave it empty to rely only on the maximum cost per run you set in Apify, which the actor also honors.
batch_size	Rows in flight per platform. Leave empty for the measured default in the table above.
twitch_client_id, twitch_app_token	Optional. Your own Helix credentials; with both set, Twitch reads use the official API.

Change rows carry change_type, change_from, change_to, and previous_run_at, plus the current profile and link columns so the row stands on its own.

📤 Output

Exports to JSON, CSV, Excel, HTML or XML. One flat, snake_case row per creator per platform, 59 columns, with null rather than a missing key. No nested objects, so it drops straight into Clay, a spreadsheet or a warehouse table without a flattening step. Nested data lives only in columns ending _json, as a JSON string, so a Clay column reads one cell.

The first run for a list returns one first_seen row per creator, the baseline; this is one from a gate run. A later change row carries change_type, change_from, change_to, and previous_run_at the same way, plus the current profile and link columns. The row below is trimmed to the columns this actor fills; a run with no changes returns one no_change row and nothing else, and that row is not charged.

💡 Tips

• Keep list_name stable per list. A new name starts a new baseline and returns first_seen for every creator.
• Read change_type first, then change_from and change_to. A milestone row says which threshold was crossed in which direction.
• Turn check_links off on a large list you only want sized. The recheck is the base price; the link page adds the newsletter, product, and manager changes. You can mix the two on one list: an off run carries the link columns forward and reports no link change, so the next on run diffs against the last real read.
• Add new handles to the same list at any time. They get a first_seen row on their first run and diff from then on.

⚠️ Known limits

Business email coverage. Business email coverage is partial. The actor fills business_email only when a creator publishes one: in a bio, a link-in-bio page, or a YouTube channel description. YouTube keeps its business email button behind a sign-in and a CAPTCHA, which the actor does not bypass; in testing, 2 of 5 channels published an address in their description instead. Empty business_email means no public address was found, not that none exists.

The first run is a baseline, not a change. Every creator returns first_seen once, and that row is charged as a change row.

State lives on your account. The named key value store creator-change-monitor-state holds one key per list_name; delete the key and the next run starts over.

Some fields are not exposed without login. What each platform does not expose without login, and what the row says instead: YouTube's business email sits behind "View email address" and a verification step, so it is not read and business_email is filled only from an address written in the public description; Instagram has no location field, so country_guess comes from the bio; Threads and podcasts have no per post engagement; podcasts have no follower count; TikTok's anonymous render carries no region, so the country comes from the bio.

No country filter. Every row carries country_guess and country_guess_method from the profile read, and no creator is dropped for its country.

Not X, not Facebook pages, not LinkedIn. Seven platforms are read, listed above.

What is never done. No login. No CAPTCHA solving. No LinkedIn fetch. No message to anyone. No key of ours is used on your run; this actor has no AI option, and the Twitch credentials you can supply are never logged or written to a row.

What this actor shares

This run contributes the records it finds to a shared creator and agency pool that all users of this actor read from. What one run finds, the next run can read.

The toggle is contribute_to_shared_pool. It is a boolean input and it is on by default. Turn it off and the run still reads the pool and writes nothing to it.

What this actor contributes. The profile fields that changed since the last run, and any manager contact that is new.

Only public data that is already in your own output. Every field written to the pool is a field this run returned to you, read from a page the platform or the creator publishes to anyone without a login. Nothing from your Apify account, your input list, your API keys, or your own notes is sent. A contribution never deletes anything from the pool.

What a contribution is labeled with. The actor ID, the run ID, the pool key issued to the actor build, and a hash of the calling IP address, used for the rate limit and nothing else. Your Apify account and your user ID are not recorded.

Contributing is free. No event is charged for a write to the pool. If the pool is unreachable the run finishes as normal, the rows are dropped, and the run log says so.

❓ FAQ

What is a row with no handle and run_outcome= in error_reason? It is the run's summary row. A run that delivers no creator row at all writes exactly one row that says why, so you never get an empty dataset with no explanation. row_status is partial when every source answered and nothing matched (run_outcome=no_results), and error when a platform refused the request (run_outcome=blocked) or did not answer before the run's time ran out (run_outcome=timed_out). A blocked run is never reported as zero results: error_reason names the hosts reached, the hosts that refused, the hosts that timed out, and the run ID and build. The summary row carries no billable event and is never charged. A run where nothing changed is not an empty run: it returns its one uncharged no_change row, described above.

What happens when a platform is slow or refuses the run? Every request is capped by the time left in the run, and the actor stops starting new creators 90 seconds before the run's timeout so it can write what it has. A slow or refusing platform returns that creator's labeled error row and the run carries on with the rest. The run exits successfully with the rows it found, and the status message says when it stopped early.

Why did my run return one no_change row? Nothing changed since the previous run for that list_name. The run returns that one row, so an empty result is never mistaken for a failed run. It carries the list name in change_from, the count of handles checked in change_to, and the run time in read_at. The row itself is not charged; each creator reread on the run still charges creator-rechecked. Otherwise a run's row count is its change count.

Why am I charged for creators that did not change? The recheck is charged because the work is the recheck, not the result. change-detected is charged on top only for change rows.

Which milestones count? 1K, 5K, 10K, 25K, 50K, 100K, 250K, 500K, 1M and up, crossed in either direction.

Where is the saved state? In a named key value store on your own account (creator-change-monitor-state), one key per list_name. Nothing is kept by Mamba Labs.

Can I watch the link page less often than the profile? Yes, on one list. A run with check_links off carries every link column forward from the last run that read it, so nothing is wiped and no link change row fires for a column that was not read. The next run with check_links on diffs against that last real read. A change that happened between the two link reads is reported on the later one, dated to the snapshot it is diffed against, not to the day it happened.
