Create Referral Code

Generate a unique 8-character referral code (uppercase hex) for the current user. Each user can only have one code: if a code already exists, this endpoint is idempotent and returns the existing code (HTTP 200) instead of creating a new one.

POST /v1/referral/codes
Authorization: Bearer <token>
Content-Type: application/json

Request Body

{
  "signature": "0x...",
  "timestamp": 1772010600
}

Field	Type	Required	Description
signature	string	No	EIP-712 signature — accepted for forward compatibility, not verified
timestamp	uint64	No	Unix timestamp (seconds) — accepted for forward compatibility, not verified

The backend currently ignores the request body entirely (an empty body is accepted); the caller is identified solely by the session Bearer token.

EIP-712 Signature

Not verified by the backend at present; retained for forward compatibility.

Response

{
  "success": true,
  "code": "4DDDC2D4",
  "created_at": 1772010604000
}

Field	Type	Description
success	bool	Always true on success
code	string	The user's 8-character referral code (newly generated or pre-existing)
created_at	int64	Creation timestamp of the code (milliseconds)

Error Codes

Error format. Referral endpoints return errors as a plain-text body (text/plain) containing the message shown in the Message column, not a JSON object. A missing or invalid Authorization: Bearer session token returns 401 with missing bearer token / invalid session.

HTTP	Message	Description
401	missing bearer token / invalid session	Missing, expired or revoked session token
500	(database error text)	Server error (including failure to generate a unique code after 5 attempts)

There is no CODE_ALREADY_EXISTS error: an existing code is returned with HTTP 200.
