Before retrying a failed or timed-out call, read Errors, retries & idempotency (https://docs.agg.market/concepts/errors). > The API reference is generated from https://docs.agg.market/openapi/openapi.json. # Preview a withdrawal > Returns real fee + receive estimates for a withdrawal without creating one.
