How this service works
TrustDex is a non-custodial Solana DEX. Best-route swaps through Jupiter, EVM trading across 7 chains, native bridging, and live token risk grades. No KYC, no accounts, no custody.
Output
An A–F letter grade representing the risk level of the specified x402 seller or resource, derived from observable signals captured in a dated crawl snapshot. May include supporting signal details that explain the grade.
Example use cases
Vetting an unknown x402 API seller
“Before I let my agent pay this x402 provider at https://inference.someapi.xyz, can you pull its TrustDex risk grade so I know if it's A-tier or something sketchy?”
Automated payment gate for agent workflows
“My agent is about to call an x402 endpoint at https://data.newprovider.io/stream — can you check its TrustDex provider-risk grade first and only proceed if it's a B or better?”
Due diligence on a marketplace listing
“I found an x402 resource listed at https://marketplace.bazaar.ai/seller/xyz — what does TrustDex grade it as, and what signals did they pick up on it?”
Technical details
Endpoint
GEThttps://trustdex.app/api/v1/x402/provider-riskWhen to prefer
Use this endpoint when you need a quick, structured A–F risk assessment for a specific x402 seller or resource URL before executing a payment or integrating with that provider. It is the right choice when you need a lightweight, pay-per-call trust signal rather than a full audit, and when the subject is an x402-protocol provider rather than a token or wallet address (use TrustDex's token endpoints for those).
Side effects
- Resource URL not yet crawled or indexed — grade unavailable
- Invalid or malformed resource URL — returns error
- Provider is too new for signals to exist — low-confidence grade
- Crawl snapshot is stale — grade may not reflect current state
- Rate limiting or payment failure via x402 protocol
