Search & Facets API — free mock REST API for testing

A compact search engine lab with category facets, score sorting, highlights and cursor pagination.

The Search & Facets API is a query surface rather than a CRUD one: full-text search with facet counts, highlighted snippets and cursor pagination. Two endpoints, but the response is the most structurally complex in the catalog — the right target for a contract test that has to survive a nested, variable-shaped payload.

Base URL: https://funapi.dev/api/search/v1 · 2 endpoints · OpenAPI 3.1 spec and Postman collection available. New here? Read the getting started guide.

(truncated — the full response comes back when you run it)

Open and run this endpoint

What you can practise here

• Run a query and assert on facet counts as well as hits, since the two can disagree when filters are applied.
• Page through results by cursor and confirm nothing is duplicated or skipped between pages.
• Send a malformed query expression and read the 400.
• Search for a term with no matches and confirm the empty result is a 200.
