Stack Overflow Scraper — search questions & answers on 184 Stack Exchange sites

Search Stack Overflow, Server Fault, Ask Ubuntu, Data Science, Security, Math, English, Law, Workplace — any of the 184 Stack Exchange sites (plus their meta sites) — and get clean JSON: question, tags, score, views, asker, and the top answers and comments in the same request. Built for support teams, developer-relations, lead-gen and coding agents. No API key, no proxy, no browser (an optional free Stack Apps key raises the quota from 300 to 10,000 requests/day).

Use cases

• Product support monitoring — tag feed of new questions on your-product with unanswered: noAnswers; answer them before a competitor does.
• Lead generation — people asking about a problem your product solves (queries + fromDate + minViews), with the asker's profile link.
• Docs / brand tracking — questions that link to your domain (url: "*.mycompany.com*") or mention your name in the title.
• Competitive research — top-voted questions on a competitor's tag (sort: votes, sortMin), how many go unanswered, which topics recur.
• Knowledge base for RAG / coding agents — pull accepted answers for a list of question URLs or a whole tag, with code blocks preserved.
• Community intelligence — tag sizes, synonyms and related tags to size an ecosystem; user lookups to find experts on a topic.

Input

All fields are optional except the ones a mode needs (see Mode). Existing inputs (queries, site, tagged, sort, includeAnswers, limit) keep their old meaning.

Field	Type	Default	Allowed values / notes
mode	string	search	search (full text + filters), tag (feed of questions on tags), questions (by id/URL), users, tagInfo
queries	string[]	–	Free-text queries (search). One request chain per query. Empty = filter-only search
site	string	stackoverflow	API site parameter (see Reference), meta.<site>, a site URL or its name
key	string (secret)	–	Stack Apps application key → 10,000 requests/day instead of 300/IP
tagged	string	–	;-separated tags, AND semantics (python;pandas). Required in tag mode
nottagged	string	–	Exclude tags (search)
title / body	string	–	Text that must appear in title / body (search)
url	string	–	Questions linking to this URL, * wildcards (search)
user	integer	–	Asker's user id (search)
accepted / closed / migrated / notice / wiki	string	any	any, yes, no (search)
minAnswers / minViews	integer	–	Lower bounds (search)
unanswered	string	any	noAnswers (0 answers), noAcceptedAnswer
fromDate / toDate	date	–	ISO 8601 creation-date window
sort	string	relevance	search: relevance activity creation votes · tag: activity creation votes hot week month · users: reputation creation name modified
order	string	desc	desc, asc
sortMin / sortMax	string	–	Bounds on the sort field: number for votes, ISO date for activity/creation
limit	integer	20	Questions per query / feed, 1–500 (100 per API request)
maxItems	integer	1000	Hard cap for the whole run
questionIds	string[]	–	Ids or question URLs (questions mode), 100 per request
users	string[]	–	User ids, profile URLs or display-name searches (users mode)
tags	string[]	–	Tag names (tagInfo mode)
includeRelatedTags	boolean	false	tagInfo: top 30 co-occurring tags (+1 request per tag)
includeAnswers	integer	2	0–30 answers embedded per question, accepted first then by score. No extra requests
includeComments	boolean	false	Embed comments on questions and embedded answers (same request)
bodyMaxLength	integer	2000	Truncate question text (0 = unlimited)
answerBodyMaxLength	integer	3000	Truncate each answer (0 = unlimited)
dedupe	boolean	true	One item per question even when several queries match
fields	string[]	–	Keep only these top-level fields (id always kept)

Unsupported combinations are not silently dropped: an invalid sort for the mode, a sortMin on relevance, an unparsable date or a question id that does not exist produce a WARN line in the log; an unknown site or a throttled IP fails the run with an explicit message.

Reference

Sort options by mode

Mode	Endpoint	sort values	sortMin/sortMax type
search	/search/advanced	relevance, activity, creation, votes	number (votes) / date (activity, creation); none for relevance
tag	/questions, /questions/no-answers, /questions/unanswered	activity, creation, votes, hot, week, month	number / date; none for hot, week, month
users	/users, /users/{ids}	reputation, creation, name, modified	–

Quota

Setup	Requests / day	Notes
No key	300 per IP	Shared by every actor run leaving the same Apify IP — fine for a few runs a day, not for heavy monitoring
With key	10,000 per key	Register a free app at stackapps.com/apps/oauth/register; the key is not secret-sensitive but is passed as a secret input

One page of up to 100 questions including answers and comments = one request. The actor honours the API backoff field, spaces requests ≥120 ms apart and stops immediately on throttle_violation (error 502) instead of retrying.

Field	Type	Meaning
id	integer	Question id (stable; unique together with site)
site, siteUrl	string	API site parameter and its base URL
title, body	string	Title (entities decoded); body as plain text, code blocks kept as ``` fences, truncated to bodyMaxLength
score, viewCount, answerCount	integer	Votes, views, answers
isAnswered, hasAcceptedAnswer, acceptedAnswerId	boolean / integer	isAnswered is the site's definition (accepted or score ≥ 1 answer)
tags	string[]	Tags
createdAt, lastActivityAt, lastEditAt, closedAt	ISO date	Timestamps (UTC)
closedReason, bountyAmount, isProtected, isLocked	mixed	Moderation state
owner	object	Asker: userId, displayName, reputation, userType, link
answers	object[]	Up to includeAnswers, accepted first then by score: id, score, accepted, createdAt, lastActivityAt, body, owner, url, (comments)
comments	object[]	Only with includeComments
url, shareUrl	string	Canonical and short link
query	string	The query / tag list that produced the item (null for questions mode)
sourceUrl, fetchedAt	string	API request that returned the item (key redacted) and fetch time

users items: id, displayName, reputation, badges {gold, silver, bronze}, location, websiteUrl, isEmployee, reputationChangeYear/Month, createdAt, lastAccessAt, url, query. tagInfo items (one per tag that exists; unknown tags are not items and are not charged — they are listed in SUMMARY.notFound): id/name, found, questionCount, synonyms, hasSynonyms, isModeratorOnly, isRequired, lastActivityAt, related [{name, count}], url.

The key-value store record SUMMARY holds { mode, site, items, requests, quotaRemaining, quotaMax, duplicatesSkipped, notFound, notFoundCount } — notFound lists unknown tags (tagInfo) and question ids the site did not return (questions).

Use it from code / agents

Apify API (curl):

curl -X POST "https://api.apify.com/v2/acts/yadroo~stackexchange-search/run-sync-get-dataset-items?token=$APIFY_TOKEN" \
  -H 'content-type: application/json' \
  -d '{"mode":"tag","tagged":"apify","unanswered":"noAnswers","sort":"creation","limit":20}'

JavaScript (apify-client):

import { ApifyClient } from 'apify-client';
const client = new ApifyClient({ token: process.env.APIFY_TOKEN });
const run = await client.actor('yadroo/stackexchange-search').call({ queries: ['hono middleware vercel'], includeAnswers: 2, limit: 10 });
const { items } = await client.dataset(run.defaultDatasetId).listItems();

Python (apify-client):

from apify_client import ApifyClient
client = ApifyClient(token)
run = client.actor("yadroo/stackexchange-search").call(run_input={"mode": "questions", "questionIds": ["11227809"], "includeAnswers": 3})
items = client.dataset(run["defaultDatasetId"]).list_items().items

MCP: add https://mcp.apify.com to Claude, Cursor or any MCP client and the actor is available as the tool yadroo/stackexchange-search; the input schema above is what the agent sees.

Pricing

Pay per event: $0.001 per run start + $0.002 per item (question, user or tag). Failed runs (bad site, throttled IP) produce no items and cost only the start fee.

Typical runs: 20 questions with answers ≈ $0.041 · a 200-question tag feed ≈ $0.401 · a daily 50-question support radar ≈ $0.101/day.

Limits & FAQ

• Quota. 300 requests/day per IP without a key; the Apify IP is shared, so pass a key for anything scheduled. One request = up to 100 questions with answers and comments.
• Freshness. Live data from the official Stack Exchange API 2.3; the API itself caches for ~60 s.
• Blocks & errors. The actor sleeps for the API-requested backoff, retries transient 5xx/503 twice, and fails fast with a readable message on throttle_violation, bad parameters or an unknown site. Missing question ids and unknown tags are logged as warnings and listed in SUMMARY.notFound, not returned as (charged) items.
• OR-tags. The API only supports AND on tagged; run one input per tag or use queries.
• Search relevance. /search/advanced matches title and body; very short or generic queries return many results — combine with tagged, fromDate, minViews.
• Answer count. includeAnswers caps the embedded answers; answerCount always reflects the true total.
• Content licence. Posts are CC BY-SA; keep attribution (url, owner.link) when you reuse the text.
• Roadmap. Per-answer comment pagination, bounties feed (/questions/featured), and OAuth access_token for inbox / private data if there is demand.
