Returns a JSON object with an 'ok' boolean, 'kind' field (e.g. 'provider'), a letter grade (e.g. 'B'), a numeric score (0-100), and a 'reasons' array listing specific risk factors detected.
Example use cases
Pre-payment x402 safety check
“I'm about to call an x402 endpoint at https://api.example.com/v1/data — can you grade its provider risk and let me know the score and any red flags before I authorize the payment?”
Automated agent payment gating
“Before my agent pays any x402 resource, run a risk check on https://rpc.newprovider.com/api/v1/endpoint and only proceed if the grade is B or better.”
Vetting a new DeFi API vendor
“I found a new pay-per-call API at https://defitools.xyz/api/prices — can you check its x402 provider risk grade so I know whether to trust it with micropayments?”
Technical details
Endpoint
GEThttps://rpc.hostdefi.com/api/v1/x402/provider-risk?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to verify the safety and trustworthiness of an x402 pay-per-call resource before authorizing a micropayment. It is the right choice when you want a letter-grade risk signal (A-F) plus a numeric score for x402 providers specifically, particularly in automated agent workflows that need a gate before spending USDC.
Side effects
- Missing or invalid 'resource' query parameter returns an error response
- Unknown or unreachable provider URL may return low score or grade F
- Network timeout if the target resource is offline
- Malformed URL input may cause validation failure
- Provider not indexed in risk database may return limited data
