JSONPlaceholder
JSONPlaceholder is a free fake REST API — no key, no signup — that serves canned, CRUD-able JSON for six resources (posts, comments, albums, photos, todos, users) plus their nested relationships, making it a go-to backend stand-in for frontend tutorials and API-client testing. Write requests (POST/PUT/PATCH/DELETE) are accepted and return a fake successful response but don't actually persist any data. Maintained by the same author as json-server, it's been stable and effectively unchanged for years.
