Changelog
2026-06-03 — Initial API surface
The first published version of the relayer API. This is the first entry; nothing precedes it.
Endpoints in this release:
| Method | Path | Auth |
|---|---|---|
POST | /auth/challenge | no |
POST | /auth/login | no |
POST | /rfq | yes |
GET | /rfq/inbox | yes |
POST | /rfq/:id/quote | yes |
POST | /rfq/:id/confirm | yes |
GET | /rfq/:id/bundle | yes |
GET | /margin | no |
GET | /firm/:addr | no |
GET | /makers | no |
GET | /takers | no |
GET | /health | no |
- Auth is challenge then login; login returns a 1-hour JWT.
- The trade path (quote, confirm, bind) is authorized by EIP-712 Terms signatures, not a session.
