Service-account API key (tfk_test_/tfk_live_).

Query Parameters

status

enum<string> | null

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

corridor

string | null

Keep only counterparties eligible to quote this corridor slug, e.g. optimism-base.
