> **For coding agents and LLMs:** This is one page from the Social Fetch docs (markdown export). For curated orientation and workflow guidance, start with [`/llms.txt`](https://www.socialfetch.dev/llms.txt); for agent onboarding and crawl rules, use [`/agents.txt`](https://www.socialfetch.dev/agents.txt); for the full endpoint list with links to pages like this one, use [`/llms-endpoints.txt`](https://www.socialfetch.dev/llms-endpoints.txt); for one platform's parameters and curls, use [`/llms-{platform}.txt`](https://www.socialfetch.dev/llms-tiktok.txt); use [`/llms.json`](https://www.socialfetch.dev/llms.json) when you need structured JSON for tool registration. ## This page - **On-site (HTML):** - **Markdown (.mdx) URL:** ## API base URL and authentication - **API origin (from OpenAPI `servers`):** `https://api.socialfetch.dev` - **Authentication:** send `x-api-key: sfk_...` on `/v1/**` and `/v2/**` routes unless the operation is explicitly anonymous (check OpenAPI `security`, the [API reference hub](https://www.socialfetch.dev/docs/api.mdx), [`/llms.txt`](https://www.socialfetch.dev/llms.txt), or [`/llms.json`](https://www.socialfetch.dev/llms.json) for each route). - **OpenAPI JSON:** ## Recommended docs entrypoints (this site) - [Documentation overview](https://www.socialfetch.dev/docs.mdx) — top-level orientation (markdown). - [Quickstart](https://www.socialfetch.dev/docs/quickstart.mdx) — authenticate with `x-api-key`, validate auth with `whoami`, and understand the JSON envelope. - [SDK](https://www.socialfetch.dev/docs/sdk.mdx) — official TypeScript SDK guide, including `SocialFetchClient`, `Result`, and `unwrap()`. - [Capability matrix](https://www.socialfetch.dev/docs/capability-matrix.mdx) — every operation with identifiers, pagination, outcomes, media download, credits, and its SDK method. Generated from OpenAPI, so use it for route selection instead of scanning individual pages. - [Recipes](https://www.socialfetch.dev/docs/recipes.mdx) — copyable workflows (brand monitoring, transcripts, Ad Library, creator scoring, Reddit research) with credit callouts and SDK examples. - [Integrations](https://www.socialfetch.dev/docs/integrations.mdx) — MCP for AI clients, n8n verified node, Apify Store Actors, Make custom app, SDK, and REST API connection paths. - [MCP product page](https://www.socialfetch.dev/mcp) — hosted MCP overview, OAuth, Skills install. - [MCP integration](https://www.socialfetch.dev/docs/integrations/mcp.mdx) — hosted `/mcp` server, OAuth, Cursor/VS Code/Claude install snippets, 910 endpoint tools, plus docs_search/docs_read for implementation help. - [n8n integration](https://www.socialfetch.dev/docs/integrations/n8n.mdx) — install `n8n-nodes-socialfetch`, credentials, and workflow examples. - [Apify integration](https://www.socialfetch.dev/docs/integrations/apify.mdx) — Store Actors under @social-fetch, PPE billing, dataset export, and quick start. - [Make integration](https://www.socialfetch.dev/docs/integrations/make.mdx) — custom app modules for Make scenarios, API key credentials, and module catalog. - [`/llms-endpoints.txt`](https://www.socialfetch.dev/llms-endpoints.txt) — every documented operation with a direct link to that route's agent-readable markdown page (prefer this over parsing OpenAPI). - [`/llms-{platform}.txt`](https://www.socialfetch.dev/llms-tiktok.txt) — per-platform endpoint files generated from OpenAPI (parameters, credits, curls). - [`/agents.txt`](https://www.socialfetch.dev/agents.txt) — agent crawl/onboarding file with capabilities, auth rules, and allowlist. - [`/llms.json`](https://www.socialfetch.dev/llms.json) — structured machine-readable operation inventory with parameter names, pagination, outcomes, credits, and SDK mapping. - [API reference hub](https://www.socialfetch.dev/docs/api.mdx) — human-friendly index of operations with links into generated pages. - [Errors](https://www.socialfetch.dev/docs/errors.mdx) — shared error envelope and HTTP status guidance. - [Credits](https://www.socialfetch.dev/docs/credits.mdx) — metering, `402`, and planning batch jobs. - Outcome semantics such as `found`, `not_found`, and `private` are documented in [Errors](https://www.socialfetch.dev/docs/errors.mdx) and on operation pages when present in the OpenAPI contract. ## Markdown docs convention - Every docs page has a markdown twin: append **`.mdx`** to the docs pathname (for example `/docs/quickstart` → `/docs/quickstart.mdx`). - Agents that send `Accept: text/markdown` on `/docs/**` HTML URLs may receive markdown directly (same URL, `Vary: Accept`). - Published blog posts use the same convention: `/blog/{slug}` → `/blog/{slug}.mdx`, or `Accept: text/markdown` on the HTML URL (`Vary: Accept`). --- # List Stack Overflow question answers (https://www.socialfetch.dev/docs/api/v1/stack-overflow/questions/questionid/answers/get) ## Summary List the answers to a Stack Overflow question by votes, activity or time, with their text and, if asked, their comments. **Tags:** `Stack Overflow` ## HTTP - **Method:** GET - **Path:** `/v1/stack-overflow/questions/{questionId}/answers` - **Base URL:** `https://api.socialfetch.dev` ## Capability summary - **SDK mapping:** `client.stackOverflow.listQuestionAnswers({ questionId: 11227809, sort: "votes" })` - **Accepted identifiers:** `questionId` (path) - **Pagination:** cursor via `cursor`, next cursor: `data.page.nextCursor`, has more: `data.page.hasMore` - **Business outcome field:** `data.lookupStatus` with values `found`, `not_found` ## Credits - **Base:** 1 credit per successful lookup. - **Maximum on success (200):** 1 credit. - **Failed requests (`lookup_failed`, `503`):** not charged. - **Authoritative field:** `meta.creditsCharged`. ## Authentication - **`x-api-key`**: API key (`sfk_...`) ## Parameters ### `questionId` (path) - **Required:** yes - **Constraints:** type `integer`; minimum: 1; maximum: 2147483647 - **Description:** Question id on the chosen site, e.g. `11227809`. ### `site` (query) - **Required:** no - **Constraints:** type `string` - **Description:** Stack Exchange site, by its API name (`askubuntu`, `serverfault`, `math`, `ru.stackoverflow`).

Do not assume a JSON body unless the OpenAPI schema defines one for that status. - **400**: Invalid request **Retry:** Fix the request; retrying the same invalid payload will not help. - **401**: Missing or invalid API key **Retry:** Fix the API key first; retrying without changes will not help. - **402**: Insufficient credits **Retry:** Do not retry without resolving billing/credits (retrying the same request will not help). - **500**: Unexpected or billing error - **502**: Lookup could not be completed. **Retry:** May be transient; a few retries with backoff are reasonable. - **503**: Service temporarily unavailable; safe to retry with backoff. **Retry:** Usually safe to retry with exponential backoff and jitter. ### Suggested client defaults - Send the API key using the `x-api-key` header on every request. - On `503` (and sometimes `502`), retry with backoff; cap retries and surface a clear error to the user. - On `402`, surface an actionable billing message rather than blind retries. ## Examples ### TypeScript SDK ```typescript import { SocialFetchClient } from "@socialfetch/sdk"; const client = new SocialFetchClient({ apiKey: process.env.SOCIALFETCH_API_KEY!, }); const result = await client.stackOverflow.listQuestionAnswers({ questionId: 11227809, sort: "votes", }); if (!result.ok) { console.error(result.error); } else { console.log(result.value.data); } ``` ### Node.js ```javascript const response = await fetch( "https://api.socialfetch.dev/v1/stack-overflow/questions/11227809/answers?sort=votes", { headers: { "x-api-key": "YOUR_API_KEY" } } ); const data = await response.json(); console.log(data); ``` ### cURL ```bash curl "https://api.socialfetch.dev/v1/stack-overflow/questions/11227809/answers?sort=votes" \ -H "x-api-key: YOUR_API_KEY" ``` ### Python ```python import requests response = requests.get( "https://api.socialfetch.dev/v1/stack-overflow/questions/11227809/answers?sort=votes", headers={"x-api-key": "YOUR_API_KEY"}, ) data = response.json() print(data) ``` ### Example: next page (pagination) After a successful response, if pagination is not finished, request the next page using `cursor` (URL-encode when composing the query string): ```javascript const previous = await response.json(); const nextCursor = previous?.data?.page?.nextCursor; const hasMore = previous?.data?.page?.hasMore; if (!hasMore || nextCursor == null) { // no more pages } else { const nextUrl = new URL("https://api.socialfetch.dev/v1/stack-overflow/questions/abc123/answers"); nextUrl.searchParams.set("cursor", nextCursor); // optionally preserve sort: nextUrl.searchParams.set("sortBy", "latest"); const nextResponse = await fetch(nextUrl.toString(), { headers: { "x-api-key": "YOUR_API_KEY" }, }); const nextData = await nextResponse.json(); } ```
