}API Reference
Solver Roster
Lists the solvers and LPs your workspace can reach - the counterparties every quote request fans out to. 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.

Query Parameters
Keep only counterparties in this roster state. Roster state of a solver/LP. active - pricing now and included in quote fan-out; standby - eligible but temporarily not pricing (maintenance or inventory rebalancing); offline - unreachable or disabled, excluded from fan-out. Eligibility itself is decided upstream of this status: only counterparties that cleared the workspace's onboarding and compliance gates appear in the roster at all.
Available options:
active, standby, offline Keep only counterparties eligible to quote this corridor slug, e.g. optimism-base.
Response
Successful Response
The workspace's counterparty roster - every solver and LP that quote requests can reach.
