POST

/auth/login

example only

The response below is an example, not a live call. A real token needs a signature over a fresh challenge message. This is an example of the shape you get back. The request on the left is exact — run it from your authenticated client.

Response

Press Example to see a sample response — this call opens a live trade and runs from your authenticated desk.

POST /auth/login is step 2 of login. It exchanges a personal_sign signature over the challenge message for a JWT valid for one hour. Send the token as Authorization: Bearer <token> on every authenticated call.

Body: { "address": "0x…", "signature": "0x…" }.
Returns: { "token": "eyJ…", "expires_at": 1780313385 } (expires_at is a Unix timestamp).
