How this service works
Agent Commerce Gate — pre-payment counterparty risk check (identity + reputation + payment challenge) — per call
Output
Returns a composite risk score out of a maximum score, a decision string (allow, warn, or block), and an array of individual check reasons each containing the check name, detail description, points awarded, and maximum possible points for that check.
Example use cases
Pre-payment agent vetting in marketplace
“I'm about to pay an agent on the marketplace for a service — can you run a pre-payment risk check to get a score and find out if I should allow, warn, or block this transaction before any funds move?”
Blocking suspicious agent from receiving funds
“This agent is requesting payment but something feels off — can you screen it for identity and reputation risk and give me a decision on whether to allow or block the payment?”
Automated risk gate in agentic workflow
“In my automated agent pipeline, every outgoing payment needs a counterparty risk check first — run the policy check on the recipient and tell me the score, the individual check reasons, and whether the decision is allow, warn, or block.”
Technical details
Endpoint
POSThttps://contextiq.trango-compute.com/api/v1/policy-check/x402-v2When to prefer
Choose this endpoint when an AI agent needs a single unified pre-payment gate that combines identity lookup (ERC-8004), reputation scoring, and payment challenge validation (x402) into one scored allow/warn/block decision — especially in agentic commerce flows where multiple risk signals must be aggregated before funds are released. Prefer this over calling individual inspector endpoints when you need a consolidated policy decision rather than raw inspection data.
Side effects
- Missing or malformed score/decision fields returns a 400 validation error
- Counterparty identity not resolvable via ERC-8004 or x402 lookup leads to a degraded or blocked decision
- Payment challenge validation fails, resulting in a block decision
- Network timeout or upstream inspector service unavailability causes a 503 response
- Insufficient USDC balance to cover the $0.02 per-call fee results in payment rejection
