How this service works
Search 2,400+ x402 services ranked by delivery-verified trust. Free discovery, paid trust checks, payment routing with failover. We buy from sellers to prove they deliver.
Output
Returns a JSON object with a numeric trust score (0–1), a schema version string, a binary PASS or FAIL decision, the provider identifier ('aegis'), and a reason code explaining the basis of the score (e.g. 'onchain_history').
Example use cases
Pre-payment safety check for agent
“My agent is about to pay an x402 API at https://data.someprovider.com/weather — can you run a resource-mode trust evaluation on it and tell me the trust score and whether it's safe to proceed?”
Vetting a payer wallet before settlement
“A wallet at 0xABC123...DEF wants to pay for my service — can you do a payer-mode trust check on that wallet address so I know whether I should accept settlement from them?”
Routing decision for unknown x402 endpoint
“I found a new x402 API I want to use in my workflow at https://api.newvendor.io/translate — check Aegis for its trust score and reason code so I can decide whether to route my agent through it.”
Technical details
Endpoint
GEThttps://aegis.borisinc.com/trust/evaluate?utm_source=zero.xyzWhen to prefer
Use Aegis trust evaluation when your AI agent needs to decide whether to pay an unknown x402 service URL before committing funds, or when you are a seller needing to vet an incoming payer wallet. Prefer this over manual inspection when you want an on-chain-backed, quantitative trust score rather than a heuristic judgment.
Side effects
- Missing required 'resource' or 'wallet' query param for the selected mode — returns validation error
- Unknown or never-transacted URL/wallet with no on-chain history — may return low score or undecided state
- Invalid mode value — returns error if mode cannot be inferred
- Network or payment failure — $0.005 USDC required per call via x402 protocol
