## 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

## 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](#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.

#### Sites (`site` parameter)

184 main sites, fetched from `/sites` on 2026-09-13. Every site also has a meta site: prefix `meta.` (e.g. `meta.askubuntu`; Stack Overflow's is `meta.stackoverflow`). Full live list: https://api.stackexchange.com/2.3/sites?pagesize=1000

| 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):

```bash
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`):

```js
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`):

```python
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.

# Actor input Schema

## `mode` (type: `string`):

What to fetch. `search` = /search/advanced with `queries` and the filters below (default). `tag` = list questions tagged `tagged` sorted by activity/creation/votes/hot/week/month — best for monitoring a product tag. `questions` = fetch specific `questionIds` with answers. `users` = user profiles by id or display name. `tagInfo` = question counts, synonyms and related tags for `tags`.

## `queries` (type: `array`):

Free-text queries for `search` mode (one API call chain per query). Each query is matched against title and body. Leave empty to search only by the structured filters below (e.g. `tagged` + `minViews`).

## `site` (type: `string`):

Stack Exchange site as the API `site` parameter: `stackoverflow`, `serverfault`, `superuser`, `askubuntu`, `unix`, `dba`, `security`, `datascience`, `ai`, `math`, `english`, `workplace`, `law`, `money`… (184 main sites) or a meta site like `meta.stackoverflow`. Site URLs (`https://askubuntu.com`) and names (`Ask Ubuntu`) are accepted too. The full dictionary is in the README; unknown values fail fast with a clear error.

## `key` (type: `string`):

Application key from https://stackapps.com/apps/oauth/register. Without a key the public quota is 300 requests/day per IP — shared with everyone else running from the same Apify IP. With a key: 10,000/day.

## `tagged` (type: `string`):

Only questions having ALL of these tags, separated by `;` (e.g. `python;pandas`). Required in `tag` mode. OR-logic is not supported by the API — run several inputs instead.

## `nottagged` (type: `string`):

Exclude questions having any of these tags (`;`-separated). Search mode only.

## `title` (type: `string`):

Text that must appear in the title. Search mode only.

## `body` (type: `string`):

Text that must appear in the question body. Search mode only.

## `url` (type: `string`):

Only questions whose body links to this URL (wildcards `*` allowed, e.g. `*.mycompany.com*`). Great for brand / docs monitoring. Search mode only.

## `user` (type: `integer`):

Numeric user id of the asker. Search mode only.

## `accepted` (type: `string`):

`yes` = only questions with an accepted answer, `no` = only without. Search mode only.

## `closed` (type: `string`):

`yes` = only closed questions, `no` = exclude closed. Search mode only.

## `migrated` (type: `string`):

Filter questions migrated from another site. Search mode only.

## `notice` (type: `string`):

Filter questions with a post notice (e.g. bounty, needs details). Search mode only.

## `wiki` (type: `string`):

Filter community-wiki questions. Search mode only.

## `minAnswers` (type: `integer`):

Only questions with at least this many answers. Search mode only.

## `minViews` (type: `integer`):

Only questions with at least this many views. Search mode only.

## `unanswered` (type: `string`):

`noAnswers` → /questions/no-answers in tag mode (client-side answerCount=0 in search mode); `noAcceptedAnswer` → /questions/unanswered in tag mode, accepted=False in search mode. Use for support / lead-gen: find people asking about your product with no help yet.

## `fromDate` (type: `string`):

Only questions created on/after this date (ISO 8601, e.g. `2026-01-01`).

## `toDate` (type: `string`):

Only questions created on/before this date (ISO 8601).

## `sort` (type: `string`):

Sort field. Search mode: relevance | activity | creation | votes. Tag mode: activity | creation | votes | hot | week | month. Users mode: reputation | creation | name | modified. Invalid combinations fall back to the mode default with a warning.

## `order` (type: `string`):

Sort direction.

## `sortMin` (type: `string`):

Lower bound on the sort field: a number for `votes` (e.g. `5` = score ≥ 5), an ISO date for `activity`/`creation`. Ignored for relevance/hot/week/month.

## `sortMax` (type: `string`):

Upper bound on the sort field (same semantics as Sort min).

## `limit` (type: `integer`):

Questions to fetch per query / per tag feed (paged 100 at a time). Each page is one API request.

## `maxItems` (type: `integer`):

Hard cap on dataset items for the whole run (cost guard).

## `questionIds` (type: `array`):

For `questions` mode: numeric ids or full question URLs (e.g. `https://stackoverflow.com/questions/11227809/...`). Up to 100 per API request.

## `users` (type: `array`):

For `users` mode: numeric user ids, profile URLs (`/users/22656/...`) or display-name searches (`inname`). Names return up to `limit` matches each.

## `tags` (type: `array`):

For `tagInfo` mode: tag names to look up (question count, synonyms, moderator-only flag, optional related tags).

## `includeRelatedTags` (type: `boolean`):

tagInfo mode: also fetch the top 30 co-occurring tags for each tag (one extra request per tag).

## `includeAnswers` (type: `integer`):

How many answers to embed per question (accepted first, then by score). Answers come in the same request as the question — no extra API calls. 0 = none.

## `includeComments` (type: `boolean`):

Embed comments on questions (and on embedded answers). Same request, larger items.

## `bodyMaxLength` (type: `integer`):

Truncate the plain-text question body to this many characters (0 = no limit). HTML is converted to readable text; code blocks are kept.

## `answerBodyMaxLength` (type: `integer`):

Truncate each embedded answer body (0 = no limit).

## `dedupe` (type: `boolean`):

Emit each question only once per run even if several queries match it (first query wins).

## `fields` (type: `array`):

Optional list of top-level output fields to keep (e.g. `["title","url","score","answers"]`). `id` is always kept. Empty = all fields.

## CLI example

```bash
echo '{
  "queries": [
    "hono middleware vercel"
  ]
}' |
apify call yadroo/stackexchange-search --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,yadroo/stackexchange-search"
        }
    }
}
```

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).
