> **For coding agents and LLMs:** This is one Social Fetch marketing page (markdown export). For API orientation start with [`/llms.txt`](https://www.socialfetch.dev/llms.txt); for auth and crawl rules use [`/agents.txt`](https://www.socialfetch.dev/agents.txt); for every operation use [`/llms-endpoints.txt`](https://www.socialfetch.dev/llms-endpoints.txt). ## This page - **On-site (HTML):** - **Markdown (.mdx) URL:** --- # Flickr Related Tags API The tags that appear alongside one tag, as a short unscored list. `GET /v1/flickr/tags/{tag}/related` returns `data.tag` (the tag you asked for) and `data.tags`, the related tag names. The list is not paged and carries no weights, so treat it as a short neighbourhood rather than a ranking. Use it to expand a tag query or to pick sibling tags, then pull photos with `GET /v1/flickr/tags/{tag}/photos`. A real tag with no related tags returns `lookupStatus: found` with an empty list; a tag that does not exist returns `not_found`. The tag photos route answers an unknown tag with `found` and an empty list instead. ## Request - **Endpoint:** `GET /v1/flickr/tags/{tag}/related` - **Credits:** 1 credit Failed requests are free - **Input:** by tag - **Full reference:** [docs](https://www.socialfetch.dev/docs/api/v1/flickr/tags/tag/related/list) - **Platform page:** [/platforms/flickr](https://www.socialfetch.dev/platforms/flickr) ## FAQ ### Does it include a relevance score? No. The related-tag list gives names only. ### Can the list be empty? Yes. A real tag with no related tags returns found and an empty list. A tag that does not exist returns not_found. An empty tag in the path is a 400. ### How much does the related tags list cost? Pricing is documented on the operation in the API registry (shown on this page). Confirm on every response with meta.creditsCharged: that field is the billing source of truth. ### Can I use a non-English tag? Yes. Put it in the path as text, for example 日本. A real tag with no related tags returns found and an empty list.
