    post:
      summary: Convert Auto Confirm
      description: >
        The endpoint requests a conversion quote and accepts it in a single
        call. No separate confirm step and no expiry window apply, so the
        10-second quote lifetime that governs [Convert
        Estimate](/api-reference/convert/convert-estimate) followed by [Convert
        Confirm](/api-reference/convert/convert-confirm) cannot elapse mid-flow.
        The spot balance funds the conversion and receives the converted amount,
        matching the two-step flow.


        The endpoint reports a conversion as executed only when the quote is
        filled and the converted amount is non-zero.


        `idempotencyKey` makes a retry safe. The key is scoped to the
        authenticated account and is claimed before anything is funded or
        executed. The first request claims the key and converts; a repeat
        returns the recorded conversion without converting again; a duplicate
        that arrives while the claim is held waits for the original and receives
        the same reply. A request that fails before anything was executed frees
        the key, so a retry converts. Without a key, a retry converts a second
        time.


        The key is bound to the request that first executed it. Reuse with
        different parameters returns `409`
        (`frontendServerSide.converter.idempotencyKeyReused`) instead of
        replaying the earlier conversion.


        The `id` returned on success is the quote ID of the executed conversion
        and is accepted as the `quoteId` filter on [Convert
        History](/api-reference/convert/convert-history).


        **Rate limit:** 10,000 requests / 10 sec per IP address — the default
        for all endpoints. See [Rate limits](/api-reference/rate-limits).


        <Warning>

        The idempotency claim is held for a few seconds and is configurable. The
        claim is taken once and is never renewed, and execution can outlast it.
        A retry sent after the claim lapses but before the original request
        finishes converts a second time.

        </Warning>


        <Note>

        For errors forwarded from the conversion service — `409` and `502` — the
        top-level `code` field is `0` and the top-level `message` field is the
        generic value `api.httpErrors.invalidRequest`. The specific condition
        appears in `errors.<field>[0]`. Branch on the HTTP status code rather
        than on `code`.

        </Note>


        <Warning>

        Do not retry a `502`, with the same key or a new one — contact support
        to reconcile. A retry with the same key returns the same `502`.

        </Warning>


        <Note>

        Error `message` values may be returned as translation keys (for example
        `validation.balance`) rather than finalized English strings. Treat the
        `code` and the field name under `errors` as the stable contract.

            The conversion service returned no usable verdict. The conversion
            may have executed. Two states produce a `502` and the response does
            not distinguish between the two: a transfer may still be
            outstanding, or the conversion was delivered and only the
            idempotency record failed to persist.
