An API client that finds your endpoints in the code
The API button in the navbar lists your project’s endpoints on its own. Pick one, try it with parameters, headers and a body, and if the response shows an error, hand it to an agent in one click.
Endpoint discovery
Endpoints come from OpenAPI/Swagger files and from routes in Express (including Fastify, Hono and Koa), Next.js, FastAPI, Flask, Django, Spring, NestJS, Go and Laravel. The scan stops at 4,000 files and skips files over 512 KB; discovery is fully local.
Sending requests
The base URL comes from the OpenAPI server, otherwise from a port an agent opened, otherwise http://localhost:3000.
- Parameters, Headers and Body tabs; send with ⌘↵.
- Requests go out from the app’s main process, so there are no CORS limits. http and https only.
- Timeout is 30 seconds by default, 120 at most; responses are capped at 2 MB.
- History of the last 40 requests per project.
