Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Query Parameters

source

string

required

Who calls it this

source_symbol

string

required

That source's spelling

Response

The instrument the spelling names

One instrument as the catalogue holds it.

The identity itself is [Instrument] from rust_types, unchanged - the same sum type the adapters and the order path work in, so a caller does not have to reassemble a futures contract from a bag of nullable fields to discover it has a multiplier. Everything outside instrument is catalogue bookkeeping rather than a property of the thing traded, which is why it sits beside it rather than inside it.

created_at

string<date-time>

required

When the platform first learned of this instrument.

instrument

object

required

What is traded, and the facts that make its price mean something.

Tagged by asset_class, so a consumer reads the class once and gets only the fields that class actually has.

Show child attributes

instrument_id

string<uuid>

required

This platform's id for the instrument. Stable across a venue renaming the symbol, which is why the API pages and links on it rather than on the symbol.

last_seen_at

string<date-time>

required

When a venue refresh last confirmed the instrument still exists.

The staleness signal: a venue that stops listing a contract usually says nothing at all, so the only evidence is a row the sync stopped touching.

status

enum<string>

required

Whether an instrument can be traded now.

Rows are never deleted from the catalogue. A future that expired last quarter is still the instrument last quarter's fills refer to, so retirement is a status change and this is what carries it.

Available options:

ACTIVE,

INACTIVE,

EXPIRED,

DELISTED

updated_at

string<date-time>

required
