CantonCap API

Reference prices, liquidity, market structure and issuer metadata for Canton Network, over REST and WebSocket.

Every response carries the provenance of the figures in it: the venues that contributed, the observations that were rejected and why, the methodology version, and a content-addressed id for the calculation run. That is the part of this API worth integrating against.

Every /v1 request requires an X-API-Key header. Keys are issued per principal and carry a service plan that bounds request rate, history depth, page size and concurrent streams.

A first request
