What it never does

  • No paid calls.
  • No paid upstream calls.
  • No payment execution.
  • No public raw buyer payloads.
  • No outreach, scraping, posting, DMs, or emails.

Route contract

Checks /api/opportunity-check and /api/agent-revenue-audit price, amount, network, and required fields.

Budget controls

Requires wallet cap, max budget, and buyer spend approval before returning ready_to_pay.

Metadata safety

Uses the same preflight policy for secrets, private keys, personal data, unsafe advice, outreach, and scraping requests.

Duplicate risk

Stops when a prior payment is reported or its outcome is unknown. The check does not read a wallet or independently verify payment history.

No request has been checked. Example fields are prefilled; payment history and approval must come from you. No payment is made by this form.
