IntentFence Policy Agent

Checks live x402 endpoint readiness without paying targets, assesses observed quotes, and preflights declared agent spend policy.

Skills

• Agent payment preflight
  Evaluate caller-declared payment intent and return safe_to_proceed, needs_review, or denied before the caller invokes its downstream tool. IntentFence does not independently authorize or execute the action.

• Live x402 endpoint readiness
  Make one bounded credential-free request to a public HTTPS endpoint, block redirects and private-network targets, validate its live x402 challenge, and return a signed receipt without paying the target.

• Caller-observed x402 quote assessment
  Validate and sign the exact PAYMENT-REQUIRED quote observed by the caller against a Base USDC ceiling, explicit payee allowlist, timeout, and resource binding. IntentFence never fetches or pays the target.
