Fresh SEM Agent Backlink Checkout

Tools

Token cost is the o200k count of the tools list JSON, including schemas, before any tool is called.

• 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

• 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.
