Obtain a short-lived ticket with `POST /v1/match/ws/ticket`, then pass two `Sec-WebSocket-Protocol` values in the upgrade request: - `circle-match.v1` - `ticket.` — the ticket value, prefixed with `ticket.` After connection, subscribe to the `market` channel for public auction state or the `account` channel for private order and fill events. See the Circle Match WebSocket reference for the full protocol specification. ## Error codes | Code | HTTP | Description | |--------|------|-------------| | 136001 | 400 | Auction locked — cancellations and less-competitive fee changes not accepted | | 136002 | 400 | Auction settling — try again after settlement completes | | 137001 | 400 | Insufficient available balance | | 137002 | 400 | Invalid wallet | | 137003 | 400 | Wallet not found | | 137004 | 409 | Idempotency key reused with different parameters | | 137005 | 400 | Fee change not more competitive during lock window | | 137006 | 409 | Self-match violation — open order on opposite side of same auction | | 137007 | 400 | Invalid fiat account | | 137008 | 400 | Maximum orders per auction reached | | 137009 | 400 | Transaction limit exceeded | | 137010 | 400 | Entity not eligible for Circle Match | | 138001 | 400 | Withdrawal amount exceeds available balance | | 138002 | 400 | Withdrawal request invalid | | 138003 | 404 | No Circle Match account found for this entity | | 138004 | 400 | Invalid withdrawal destination | | 139001 | 400 | Circle Match wallet invalid | version: 1.0.0 servers: - url: https://api.circle.com description: Production - url: https://api-sandbox.circle.com description: Sandbox security: - BearerAuth: [] tags: - name: Account description: Account balance and activity summary - name: Orders description: Place, list, retrieve, cancel, and modify orders - name: Withdrawals description: Withdraw restricted mint-side USDC - name: WebSocket description: Obtain a WebSocket connection ticket paths: /v1/match/account: get: tags: - Account summary: Get account summary description: >- Returns a best-effort snapshot of your Circle Match USDC balance, open-order exposure, and windowed activity totals.
