An id appears here only after the counterparty clears the workspace's eligibility gates (onboarding, compliance, corridor coverage); `status` then says whether it is pricing right now. An empty eligible roster for a pair is exactly what surfaces as a typed productUnavailable answer on POST /quotes. ## OpenAPI ````yaml /api-reference/specs/rfq-api.json get /solvers openapi: 3.1.0 info: title: TetraFi RFQ API version: '1' description: >- Firm, escrow-backed quotes from competing solvers and LPs. Every quote is a signed commitment priced from the counterparty's own inventory - executable exactly as returned, with no re-pricing and no last look - and every order settles through a delivery-or-refund escrow: the output is delivered or the input comes back, never limbo. servers: - url: https://api.tetrafi.io/api/v1/rfq description: >- RFQ namespace base URL.
