Beeceptor
Stand up a named mock REST endpoint in seconds with no signup, or hit Beeceptor's ready-made public sample APIs for instant fake JSON.
Beeceptor lets you claim a subdomain (e.g. myapp.free.beeceptor.com) and immediately have a live mock API: by default it echoes/captures requests, and you configure conditional and dynamic mock rules (path matching, templated JSON, status codes, delays) from the dashboard. It also publishes a set of zero-config public sample APIs on dedicated hosts (fake-json-api.mock.beeceptor.com for users/companies, dummy-json.mock.beeceptor.com for todos/posts) that return realistic canned JSON with no setup, plus an echo/inspector at echo.free.beeceptor.com that reflects whatever you send. That makes it useful both as a fake backend for an AI automation and as a request inspector. The forever-free tier needs no signup or card.
