Get an RFQ
Returns one RFQ visible to the caller’s member by its exchange id — one the member raised, or one soliciting quotes from it.

objectrequester_idobjectThe pseudonymous participant identifier of the user who raised this RFQ. Stable across that user's RFQs so makers can correlate repeat requesters; on your own RFQs it equals your `rfq_participant_id` from `GET /users/me`.
Show propertiesHide properties
objectclient_rfq_idobjectThe requester's correlation id for this RFQ. Present only on RFQs raised by the caller's member; it is the requester's private correlation id on RFQs soliciting the caller.

objectlegsRfqLeg[]requiredThe component legs of the RFQ.

objectstatusRfqStatusrequiredAn RFQ's status. `open` is still soliciting quotes; `rejected` was rejected by the exchange; `closed` is otherwise terminal (the RFQ was accepted, expired, canceled, or otherwise concluded without a trade).
Allowed:
openclosedrejectedcreated_atstring<date-time>When the RFQ was created. UDX timestamps use RFC 3339; requests require an explicit UTC offset and zero to six fractional digits; responses use UTC with exactly six fractional digits.
max length 40
expires_atstring<date-time>When the RFQ stops soliciting quotes. A quote must be submitted, accepted, and confirmed within this deadline. UDX timestamps use RFC 3339; responses use UTC with exactly six fractional digits.

401No valid credential was provided.
typestring<uri-reference>A stable URI identifying the error's general category. Usually absent (equivalent to "about:blank" per the RFC); documented rate controls use closed URN values so callers can distinguish same-status retry causes without parsing localized prose.
max length 2048
titlestringrequiredA localized, human-readable summary of the error category. Stable for a given status code and resolved language — clients must not use it as a machine-readable discriminator.
max length 40
statusintegerrequiredThe HTTP status code, repeated from the response itself.
detailstringA localized, human-readable explanation specific to this occurrence. Clients must not parse it for machine-readable information.
max length 500
instancestring<uri-reference>An identifier for this specific occurrence, so it can be correlated with server-side logs if you need to report it.
