Authentication

Solving endpoints require an API key. Health check does not.

Endpoint	Auth
GET /health	No
GET /v1/solvers	Yes
POST /v1/solve/:type	Yes

Get a key

1. Register in the console
2. Open API Key
3. Copy the default site-key (created on signup; you can create more keys later)

Charges are billed to the account that owns the key.

Headers

Either header works (Bearer preferred):

Authorization: Bearer <site-key>

X-API-Key: <site-key>

Missing or invalid key → 401:

{
  "ok": false,
  "type": null,
  "error": { "code": "UNAUTHORIZED", "message": "invalid api key" },
  "cost_ms": null
}

Password reset

Use Forgot password on the console login page. An email code is required to set a new password.
