How this service works
3-node swarm that scores x402 Payment Required calls and returns a GO/NO-GO credit recommendation.
Output
Returns a JSON object with a final_creditability_score (integer), final_recommendation (GO or NO-GO), trust_level string, an array of node_reports from three independent analysis nodes, aggregated_flags listing detected risk signals, and agentcash_intel with additional on-chain context. Optionally includes a caller_id for AgentMail alert routing.
Example use cases
Pre-payment safety check for autonomous agent
“My agent just hit a 402 on https://data.vendor.io/feed with payTo 0xDEADBEEF and a request for 1000 sats — run it through the swarm and tell me if I should let it pay.”
Vendor due diligence before onboarding
“Before I whitelist this x402 vendor at https://api.newvendor.io/query — vendor ID vendor_42, dispute ratio 0.03, fulfillment rate 0.94 — can you get me a creditability score and recommendation?”
Real-time fraud detection in agent payment loop
“My payment agent is about to settle a 200-sat USDC request on Base from endpoint https://feeds.unknown-service.xyz/live — check if that endpoint and payTo address 0x1234ABCD look legitimate before it goes through.”
Technical details
Endpoint
POSThttps://x402-crediting-swarm.vercel.app/api/swarm?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a structured GO/NO-GO decision before settling an x402 micropayment on Base mainnet — especially when vendor history, payTo address legitimacy, or endpoint reputation are unknown. Prefer this over simple on-chain lookups when you need multi-node consensus scoring and aggregated fraud flags rather than a single data point.
Side effects
- HTTP 402 with PAYMENT-REQUIRED body if the $0.05 USDC x402 payment is not included or fails to settle
- HTTP 400 if the request body is missing the required payload object
- HTTP 402 if payment settlement via the CDP facilitator fails after submission
- Malformed or incomplete vendor metadata may degrade scoring accuracy without returning an error
