> **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 Flickr group pool (https://www.socialfetch.dev/docs/api/v1/flickr/groups/groupid/photos/list) ## Summary List a Flickr group pool, newest first. **Tags:** `Flickr` ## HTTP - **Method:** GET - **Path:** `/v1/flickr/groups/{groupId}/photos` - **Base URL:** `https://api.socialfetch.dev` ## Capability summary - **SDK mapping:** `client.flickr.listGroupPhotos({ groupId: "central" })` - **Accepted identifiers:** `groupId` (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`, `hidden`, `private`, `restricted` ## 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 ### `groupId` (path) - **Required:** yes - **Constraints:** type `string`; minLength: 1; maxLength: 80; pattern: `^(?:[0-9]{1,20}@N[0-9]{2}|[A-Za-z0-9][A-Za-z0-9._-]{0,79})$` - **Description:** Group NSID (`34427469792@N01`) or path alias (`central`). ### `cursor` (query) - **Required:** no - **Constraints:** type `string`; minLength: 1; maxLength: 2048 - **Description:** Cursor from `page.nextCursor` of the previous response. It only works with the same filters. Send it without `page`; it keeps the page size it was issued with, so `limit` may be sent again and has no effect. ### `page` (query) - **Required:** no - **Constraints:** type `integer`; minimum: 1; maximum: 1000000 - **Description:** Page number, 1-based. Default: 1. A page past the last returns an empty list with `hasMore: false`. Prefer `cursor` when continuing. ### `limit` (query) - **Required:** no - **Constraints:** type `integer`; minimum: 1; maximum: 100 - **Description:** Rows per page, 1 to 100. Default: 100. ## Pagination This endpoint uses **cursor-based pagination** via the `cursor` query parameter. - Read **hasMore** from `data.page.hasMore`. - When that value is `true`, read **nextCursor** from `data.page.nextCursor` and pass it as the `cursor` query parameter on the **next** request (URL-encode when building a query string). - Omit `cursor` on the **first** request. - Stop when **hasMore** is `false` or **nextCursor** is null (end of list). ## Responses (status codes) - **200**: Flickr group pool. - **400**: Invalid request - **401**: Missing or invalid API key - **402**: Insufficient credits - **413**: The document is larger than the maximum size we can return; no charge. - **500**: Unexpected or billing error - **502**: Lookup could not be completed. - **503**: Service temporarily unavailable; safe to retry with backoff. ## Response body (200) Flickr group pool. ### Field outline - **data** (required) — type `object`.
