Body

application/json

Quotes lock an FX rate (or a 1:1 spot for same-asset) for a short window and are required by every operation creation endpoint. A quote is bound to a specific account and can be consumed by exactly one operation on that account.

Provide exactly one of sourceAmount or targetAmount:

• sourceAmount — fix the amount you'll spend; the target side is computed.
• targetAmount — fix the amount the beneficiary receives; the source side is computed.

Same-asset quotes (sourceAsset == targetAsset) are valid and return a 1:1 spot with zero spread.

accountId · string<uuid> · required

Account the quote is bound to. The consuming operation must reference the same account.

Example:

"a1b2c3d4-5e6f-7890-abcd-ef1234567890"

sourceAsset · enum<string> · required

ISO 4217 currency code or stablecoin ticker. The maximum decimal scale of an AmountValue paired with this asset depends on the asset:

USD	2	NZD	2
BRL	2	CHF	2
EUR	2	NOK	2
CAD	2	DKK	2
AUD	2	PLN	2
GBP	2	SEK	2
MXN	2	USDC	6
HKD	2	USDT	6
SGD	2	EURC	6
PHP	2	BRLT	6

Available options: USD, BRL, EUR, CAD, AUD, GBP, MXN, HKD, SGD, PHP, NZD, CHF, NOK, DKK, PLN, SEK, USDC, USDT, EURC, BRLT

Pattern: ^-?\d+(\.\d+)?$

Example:

"500.00"

targetAmount · string

Decimal monetary amount in the associated asset. The number of fractional digits must not exceed the asset's precision — see Asset for the per-asset table. Exceeding the precision fails with INVALID_AMOUNT_PRECISION.
