Sign `safe_tx` and relay it through `POST /account/wallet/relay` with this `quote_id` before `expires_at` (5 minutes); a quote can be used once. `fee` is ours, `max_cctp_fee` the most Circle may keep, `receive` the minimum you receive. `destination` must be a checksummed address other than your wallet; a wallet (not passkey) account can withdraw only to its linked wallet. Refusals are 422 with `code`: `below_minimum`, `withdrawals_disabled`, `chain_inactive`, `receive_not_positive`, `no_safe`, `no_wallet`, `destination_is_safe`, `destination_not_linked_wallet`. Rate limited to 10 per minute. ## OpenAPI ````yaml /api-reference/openapi/calibri.yaml get /api/v2/atlas/account/bridge/withdraw/quote openapi: 3.1.0 info: title: Calibri API version: 1.0.0 description: >- The Calibri API.
