How this service works
Machine-payable trust and payment-safety APIs for autonomous agents: rank counterparties before delegation, screen wallets before USDC settlement, buy signed AGD-1/AGPD-1 decisions, seal authenticated machine messages, and retain offline-verifiable evidence. Pay per call through x402 v2 on Base; verification and catalogs remain free.
Output
Returns a JSON object with: trust tier ('deep'), a policy object including decision (allow/block) and reasons, a history object with observation count and drift indicators, a corroboration object with independent sources, and an index_status string (e.g. 'recently_reachable'). Also includes a top-level verdict ('pass'/'fail'), lists of checks performed, failed checks, and unknowns.
Example use cases
Pre-delegation safety check for agent
“I'm about to let my AI agent call out to a third-party fulfillment agent at api.fulfillment-agent.xyz — can you run a deep trust preflight on that endpoint first and tell me if the policy decision is allow or block?”
USDC settlement counterparty screening
“Before my agent sends 50 USDC to this counterparty endpoint, do a deep trust check on it and show me its behavioral history and how many independent corroboration sources back it up.”
Behavioral drift detection for recurring agent
“We've been using a partner agent endpoint weekly — run a deep preflight check on it now so I can see if there's any behavioral drift or new policy flags I should know about before this week's run.”
Technical details
Endpoint
GEThttps://agent-guild-5d5r.onrender.com/preflight/deepWhen to prefer
Choose this deep preflight endpoint when you need the most comprehensive trust assessment before delegating to or paying an autonomous agent counterparty — especially when behavioral drift, independent corroboration, and a signed policy decision are all required. Use it over lighter-weight trust checks when the stakes (financial settlement, sensitive data, irreversible actions) are high enough to justify the $0.02 per-call cost and slightly higher latency compared to shallow preflight variants.
Side effects
- Endpoint not indexed — index_status may indicate 'unknown' or 'unreachable', limiting history and corroboration data
- Insufficient corroboration sources — fewer than 2 independent sources reduces confidence in verdict
- Payment failure via x402 — if USDC payment of $0.02 is not accepted, the call is rejected before assessment
- Target endpoint unreachable — history and reachability checks may fail if the subject URL is down
- Schema mismatch — missing required 'type' or 'method' fields in input returns a 400-level error
