Build your integration
The menu above is organised by what you are building. Most of it is capability — trading, market data, getting accounts in front of traders. Two of them are not, and they apply to all the rest: API Standards is the contract’s cross-cutting rules, read once; Conformance is how you prove your integration follows them before it touches a live account.Connect venues / Create venues
The two ways a trader gets an account: connect a venue you already run, or have us create the
accounts on ours. Whose venue it is turns out to be the only thing that really differs.
API Standards
Keys, authentication, errors, rate limits, idempotency, paging, streaming.
Conformance
The checks an integration passes, the evidence, and how to submit it.
