Signup

GET /api/v1/signup/resolve

Resolve a signup-link token into claim context (unauthenticated)

Verify a signup ``rid`` token and return the claim context. * ``200`` — valid token: ``{name, country_code, brand_id, identifier_masked, maps_byok_key_or_null}``. * ``401`` — token expired, signature invalid, or malformed (detail masked). * ``410`` — token minted before B.1 (no ``brand_id``); ask for a fresh link.

Parameters

token string query required

GET /api/v1/signup/check-name

Check whether a VayaPin name is available (unauthenticated, token-authz)

Verify a signup ``rid`` token and report whether ``name`` is available. * ``200`` — ``{is_available, suggestions}``: free name → empty suggestions; taken name → up to 10 alternatives the cs-api proposed. * ``401`` — token expired, signature invalid, or malformed (detail masked). * ``410`` — token minted before B.1 (no ``country_code``); ask for a fresh link. * ``429`` — per-token rate limit exceeded (5/s or 60/min). * ``502`` — cs-api returned an uninterpretable availability body (our bug). * ``500`` — cs-api credential misconfigured (our bug). * ``503`` — cs-api temporarily unavailable.

POST /api/v1/signup/complete

Finalise a consumer claim — write the pin and notify the agent

Write the claimed pin to cs-api and fire ``pin_created``. Anonymous by design (2026-06-22 rescope): the consumer reaches this with no better-auth session, so ``session`` is ``None`` on the V1 path. The signup ``token`` — not a login — is the claim authorization. * ``202`` — accepted: ``{vayapin_id, state}`` (``done`` | ``creating``). * ``401`` — token expired / invalid (the signup token, not a session). * ``404`` — no reservation for this token (confirm-pin never persisted it). * ``409`` — body name/country does not match the reserved claim. * ``502`` — cs-api reported a terminal failure writing the pin. * ``503`` — write path disabled, or cs-api transiently unavailable.
