# Accept RFQ quote

Accept a previously requested RFQ quote and place the RFQ order.

:::note[Availability]
RFQ trading is available to UK customers with passed KYC/KYB.
Additionally, UK retail clients must be categorised as High Net Worth investors.
:::

Pass the `signature` token from the [Request RFQ quote](https://developer.revolut.com/docs/api/revolut-x-crypto-exchange#request-rfq-quote) response.
The quote's terms (pair, side, size, and price) are taken from the signed token — they cannot be modified.

The signed token is bound to your account.
Treat it as single-use: once the downstream order has been submitted, retrying it does not create a second order.
If acceptance fails before submission, request a new quote rather than relying on replay.
- Tokens that are invalid or tampered with are rejected with `400`.
- Tokens that have expired are rejected with `422`.
- Tokens issued to a different account are rejected with `403`.

If immediate execution or the fincrime decision rejects the order, the endpoint returns `status: rejected` with a `reason`.
Insufficient balance and other processing failures are returned as HTTP errors instead.

#### Rate limits

| :--- | ---: | :--- | :--- |
| **Per-second limit** | 5 | 5 tokens / second | 1 token / request |

For retry guidance, see the `429 Rate Limit Exceeded` response below. The `Retry-After` header specifies the delay in milliseconds.
