> **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.

## API base URL and authentication

- **API origin (from OpenAPI `servers`):** `https://api.socialfetch.dev`
- **Authentication:** send `x-api-key: sfk_...` on `/v1/**` 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).

- [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.

- [`/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`).

# Facebook API reference (https://www.socialfetch.dev/docs/api/v1/facebook)

Social Fetch's Facebook tag is sixteen `GET /v1/facebook/...` routes. Pass a Page URL, post permalink, group URL, Marketplace listing, or Ad Library query and get `{ data, meta }` with `data.lookupStatus`, `meta.requestId`, and `meta.creditsCharged`. Authenticate with `x-api-key` only — no Meta app review, page token, or ads account.

These pages are generated from the public OpenAPI spec. Product overview and credit notes also live on the [Facebook platform hub](/platforms/facebook). Vendor comparison: [Best Facebook data APIs](/blog/best-facebook-data-apis-2026). Ad Library workflow: [Facebook Ad Library recipe](/docs/recipes/facebook-ad-library).

  Every Facebook route is **1 credit** per completed lookup, and paginated feed, comment, Marketplace, and Ad Library calls bill **each page**. The one add-on: `hostMedia` on profile posts, reels, and photos bills **+2 credits per hosted asset**. Trust `meta.creditsCharged`.
