Price Lock

External Buy Quote

Generate a price-locked quote for an External Buy onramp transaction (crypto withdrawn to an external wallet). Pass the returned quote id as quote_id when creating the transaction to lock the price.

Onramp Price Lock

An External Buy transaction is price-locked only when it is created from a quote. Call this endpoint first, then pass the returned quote id as quote_id when creating the External Buy transaction.

Authentication uses the same HMAC client auth as the other client endpoints.

Request rules

Provide exactly one of from_amount or to_amount — not both, not neither.
network is required because the crypto withdrawal leg sends funds to an external wallet.

Response fields

Field	Meaning
`id`	Quote id. Pass this as `quote_id` when creating the transaction.
`network`	Network the locked quote applies to.
`expiry`	Price-lock expiry. The quote must be used to create a transaction before this time.
`settlement_expiry`	Deadline by which the transaction must be completed (deposit settled).
`final_price`	Locked price used for the transaction.
`min_crypto_amount`	Minimum crypto amount that can be withdrawn on this network.
`fee_breakup` keys	`platform_fee`, `network_fee`, `client_fee`, `discount`, `tax_on_fee`, `tds`

A quote is single-use and tied to the client that created it.
