Fetch one crypto deposit by id
The deposit in its current state, including a FAILED record, which is reported as the object rather than as an error. This is the fetch half of the thin crypto_deposit.credited webhook payload. The id is stable across replays of the same on-chain transfer.

Every recorded arrival at your deposit addresses, newest first — credited deposits and FAILED records alike. A deposit appears here the moment it is recorded; there is no POST, because a crypto deposit is initiated on-chain and the transfer itself is the request.
Convert one currency you hold into another POST
Sells an exact amount of fromCurrency for toCurrency between two accounts you already hold, executed by TCB's trading pipeline. It is a stage in its own right, not something the deposit or withdrawal endpoints do for you: convert first, read the rate you got, then deposit or withdraw. An idempotency key is MANDATORY: send it as the Idempotency-Key header or as the idempotencyKey body field. Replaying a key returns the original result without re-executing; reusing one with different parameters is rejected with IDEMPOTENCY_KEY_REUSED. The rate comes only from an external venue that prices independently of TCB. When no such venue can price the pair, the request is refused with 503 PRICING_UNAVAILABLE and nothing is converted — TCB never prices a conversion from an internal table instead. READ rate.pricingModel ON EVERY RESPONSE: MARKET means a venue quoted it; any other value (SIMULATED appears only on conversions settled before 2026-09-06) is not a market rate and must never be presented or reported as one. Every response also carries the pilot disclosure. Converting into a currency and straight back out is priced twice. A shared trading risk check limits order rate, size and daily volume, scoped to your client principal — every sub-account shares one bucket. A refusal is 400 CONVERSION_RISK_REJECTED with details.reasons listing the failed checks. Name toAccountId to end the conversion in another account of your tree: one of your own fiat accounts in toCurrency, or a sub-client's. Into a sub-client's account the converted amount lands in your own account first and moves on in the same step that settles the conversion; transferId names that move. A key naming toAccountId needs transfer:execute as well as trade:execute. To see the rate and the commission before you convert, quote the conversion first (POST /conversions/quote) and name the quoteId here: the conversion then executes at that quote and is never re-quoted. Every response states the commission charged (commission) and networkFee, which is always null: TCB covers any network cost.
