## Pricing

from $0.32 / 1,000 account founds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

### Instagram user ID finder: username → ID and ID → username

**Paste usernames or IDs, mixed, and get both for each account — with its name, followers and flags.**

- 🔁 **Both ways** — `natgeo` → `787132`, `787132` → `natgeo`.
- 🏷️ **Renamed accounts** — an ID still finds the account after the username changed.
- 📋 **Bulk** — thousands per run; duplicates free.
- 🔓 **No login**; IDs and usernames that don't exist are free.

### Why this one

- 🔓 **No Instagram login or cookies** — you paste usernames, links or keywords; your own account is never involved.
- 🧾 **Free rows, not silent gaps** — private, deleted or missing items come back as free rows with an `error` reason; duplicates are never returned or charged.
- 🧯 **Your budget is a hard stop** — set **Maximum cost per run** and the run stops at your limit (the run summary says so).
- 📊 **A summary you can check** — every run saves a `SUMMARY` record: results, free rows, what was skipped and why.
- 🚫 **`null`, never a fake `0`** — when Instagram hides a number (hidden likes, saves on photos), you see that it's missing.

### Why scrape Instagram user IDs?

- **Usernames change, IDs don't:** store the ID and find the account again after a rename.
- **Developers:** the ID that Instagram's APIs and other tools expect.
- **Both ways:** username → ID and ID → username in one run.

### How to scrape Instagram user IDs

1. Paste usernames or links into the input, one per line.
2. Press **Start** — rows stream into the Output tab while the run goes.
3. Download them as JSON, CSV, Excel or HTML, or get them through the API.

Works with any public profile on [Instagram](https://www.instagram.com/) — no login, no cookies, no Instagram account
of yours.

**No input at hand?** Press **Start** with an empty input — you get a 3-row sample.

### Input example

```json
{
  "usernames": [
    "natgeo",
    "787132"
  ]
}
```

### Output example: Instagram user IDs data

```json
{
  "input": "natgeo",
  "username": "natgeo",
  "id": "787132",
  "fullName": "National Geographic",
  "profileUrl": "https://www.instagram.com/natgeo/",
  "isPrivate": false,
  "isVerified": true,
  "followers": 283000000
}
```

Each row has up to 9 fields — the **Output** tab describes every one of them. Fields Instagram
doesn't show come as `null`, never as a fake `0`.

### Limits

- Only existing accounts; deleted ones return a free row.
- **Free Apify plan:** the first 100 results of each run. Any paid Apify plan gets every result — no cap.

### How much does it cost to scrape Instagram user IDs?

Pay per event: you pay for the rows you get, plus $0.0005 per run. No subscription to this Actor.

| Apify plan | Per 1,000 accounts | What $5 of free credit gets you |
|---|---|---|
| Free | $2.50 | ≈ 2,000 accounts |
| Starter | $0.45 | — |
| Business and higher | $0.32 | — |

Every event of this Actor on the Starter plan:

| Event | What it is | Price |
|---|---|---|
| Account found | Each username or ID matched to its account | $0.45 per 1,000 |

**Typical jobs on Starter:**

- IDs of 1,000 usernames ≈ $0.45

**Always free:** IDs and usernames that don't exist, duplicates. Set **Maximum cost per run** in the run options to cap any run.

### Chain it with other Actors

Use the rows of an earlier run as the input: paste its **dataset ID** into *Or: dataset from another run*. For example,
run [Instagram Followers Scraper](https://apify.com/instagram-data-api/instagram-followers-scraper) on a brand, then give its dataset to
[Instagram Email & Phone Scraper](https://apify.com/instagram-data-api/instagram-email-phone-scraper) — you get the emails of the brand's
followers. Works with the datasets of Apify's own Instagram Actors too.

### Instagram user IDs API: Python, n8n, Make, Zapier and AI agents

Python:

```python
from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("instagram-data-api/instagram-user-id-finder").call(run_input={'usernames': ['natgeo', '787132']})
for row in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(row)
```

**n8n, Make, Zapier or any HTTP client:** one request runs the Actor and returns the rows —
`POST https://api.apify.com/v2/acts/instagram-data-api~instagram-user-id-finder/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN`
with the input JSON as the body.

**AI agents (MCP)** — your agent gets this Actor as a tool:

- **Claude Code:** `claude mcp add --transport http apify "https://mcp.apify.com?tools=instagram-data-api/instagram-user-id-finder"`
- **Claude, Cursor, VS Code, n8n:** add `https://mcp.apify.com?tools=instagram-data-api/instagram-user-id-finder` as a remote MCP server and sign in to Apify.
- **Ask it:** *“What is the Instagram ID of @natgeo?”* · *“Which account has the ID 787132 now?”*

### FAQ: scraping Instagram user IDs

**What is an Instagram user ID?**
A permanent number Instagram gives every account. The username can change; the ID never does.

**Can I paste IDs and usernames together?**
Yes — numbers are read as IDs, everything else as usernames.

**Do I need an Instagram account or cookies?**
No. You only paste usernames, links or keywords. Nothing to log in, nothing to install, and your own Instagram account is never involved.

**What am I charged for — and what's free?**
Only the events in the pricing table, plus $0.0005 per run. Rows with an `error` field are free, and duplicates are never returned or charged. Each run's `SUMMARY` record shows results and free rows.

**Can I cap what a run costs?**
Yes. Set **Maximum cost per run** in the run options — the run stops at your limit and `SUMMARY` shows `stoppedAtChargeLimit: true`.

**Can I use it from n8n, Make, Zapier or an AI agent?**
Yes, like any Apify Actor: REST API, webhooks, the n8n, Make and Zapier integrations, and the Apify MCP server for Claude, Cursor, VS Code and other MCP clients.

**Is it legal to scrape Instagram?**
We only collect what public profiles show publicly. Results can include personal data such as names, usernames or public business contacts, which laws like GDPR protect — use the data for a legitimate purpose and ask a lawyer if unsure.

        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
