## How to act

| Goal | Method | Endpoint | Auth |
|------|--------|----------|------|
| Send a project inquiry for the user | POST | `/api/contact` | None |
| Subscribe the user to the newsletter | POST | `/api/newsletter` | None |
| List services | GET | `/api/services` | Member session (sign in at `/login`) |
| MCP JSON-RPC (`submit_contact`, `list_insights`) | POST | `/api/mcp` | None |
| Check API health | GET | `/api/health` | None |

- Confirm name, email, and project details with the user before calling `/api/contact`.
- Request bodies and responses are defined in [/openapi.json](https://www.seanguillermo.com/openapi.json).
- Errors are RFC 9457 `application/problem+json` (`type`, `title`, `status`, `detail`, `code`, plus `requestId`); quote the `requestId` when reporting a failure. Unknown `/api/*` paths return a JSON 404.
- Respect rate limits: read `RateLimit` / `RateLimit-Remaining` and wait `Retry-After` seconds after a 429. Contact and newsletter allow 5 requests per minute.
- Pin long-lived integrations to `/api/v1/*`. Every response sends `API-Version`; deprecations follow the [policy](https://www.seanguillermo.com/developers#versioning) (6-month notice via `Deprecation` and `Sunset` headers).
