Requesting a quote moves no funds: it returns the provider's price and the `executionSteps` your user's wallet signs to accept it. The deposit must land onchain by the quote's `expiresAt`, 180 seconds after it's priced. `quotes` holds one quote per provider that can fill the request, so compare `fees` and `executionSteps` before picking one.Send exactly one of `senderAmount` or `receiverAmount`; the other side comes back computed on the quote. One side must be AUSD, both sides must be on the same chain, and USDT is offered on Ethereum only (see [Support](/api/guides/convert-stablecoins/overview#support)).We screen both wallets before quoting, and a request that fails for any reason stores nothing:- `400 chain_unsupported`: `sender` and `receiver` are on different chains. - `400 currency_unsupported`: the pair doesn't have AUSD on exactly one side, or the chain doesn't offer the currency (USDT on Monad). - `403 wallet_blocked`: the sender or receiver wallet failed screening. - `503 service_unavailable`: no provider can quote right now. Retry later with a new request.Next, follow [Executing a quote](/api/endpoints/quotes/overview#executing-a-quote) to run `executionSteps`, then poll `transactionId` through [`GET /v0/transactions/{txnId}`](/api/endpoints/transactions/getbyid) as described in [Tracking execution](/api/guides/convert-stablecoins/overview#tracking-execution). [Fees](/api/endpoints/quotes/overview#fees) explains the `fees` breakdown.Legal noticeThe Via API, including the /v0/quotes and /v0/transactions endpoints, is offered solely by Agora Blue Limited, a business company incorporated in the British Virgin Islands.

Reference: https://docs.agora.finance/api/endpoints/quotes/create ## Authentication - `Authorization` header (bearer token, required) — Session JWT from `POST /v0/auth/token`, sent as `Authorization: Bearer `. See [Authentication](/api/authentication) for more details. ## Request ### Body (application/json) This endpoint expects an object. - `sender` (V0QuotesPostRequestBodyContentApplicationJsonSchemaSender, required) - `receiver` (V0QuotesPostRequestBodyContentApplicationJsonSchemaReceiver, required) - `senderAmount` (string, optional) — Fixes the input side.
