You don’t have to guess at the API. SocialMate serves a full OpenAPI spec and human-readable docs locally.
Where to find them
- Machine-readable:
http://localhost:3456/docs/openapi.json— import it into Postman, Insomnia, or a code generator. - Human docs:
http://localhost:3456/docs— browse every endpoint, parameter, and example.

Tip. Point your favourite API client at the OpenAPI URL to generate a typed client in minutes. Because it’s local, the spec always matches the exact version you’re running.
All requests are validated against JSON schemas (Fastify), so malformed input is rejected with a clear error instead of doing something surprising.
