## Tools (as reported by the server, not verified)

- `describe\_backlink\_service`: Read the verified offer, price, networks, fulfilment model, safety rules, and documentation without creating an order or moving funds.
- `get\_payment\_requirements`: Read supported chains, official USDC contracts, gas assets, exact-price rules, and owner-approval guidance. This never creates an order or signs a transaction.
- `create\_quote`: Create one pending order and return exact USDC payment coordinates. This does not connect a wallet, sign, broadcast, or move funds. Keep the access token secret and obtain the wallet owner's approval before payment.
- `check\_payment`: Ask Fresh SEM to look for the exact official-USDC payment from the quoted sending wallet and return the verified order state. This never signs or broadcasts.
- `submit\_payment\_proof`: Submit a transaction hash as a lookup aid. Fresh SEM independently verifies chain, official token, sender, recipient, amount, quote time, success, finality, and single use before fulfilment.
- `get\_order\_status`: Return the authorized order state and continue safe payment reconciliation when appropriate. Treat an order as complete only when status is fulfilled.
- `check\_service\_health`: Read public endpoint availability and current MCP server information. This does not create an order or move funds.
