## API

- Base URL: `https://agent-pass.turingcorp.net`
- Auth: `Authorization: Bearer <apiKey>` on every account endpoint
- Agent-friendly: identical responses whether or not an address is registered; support tickets can be filed from code
- Limits: codes 1 per 60s / 5 per day per address; support 5 per day per email, 50 per day per network
- Credentials: the end-user Agent Pass expires after 7 days; sign in again to renew. The account page keeps a separate browser session; the Pass expiring does not sign it out.

## Get an API key

1. `POST /api/v1/auth/register/start` with `{"email": "..."}`
2. Read the 6-digit code from the email, then `POST /api/v1/auth/register/complete`
3. The response contains `apiKey` — store it; it is shown once.
