How this service works
Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.
Output
Returns a JSON object containing the network identifier (e.g. eip155:8453), the product name (e.g. quicknode-rpc-health), and an assessment object with a risk_level (e.g. 'low'), a numeric risk_score, and an array of flags indicating any governance concerns. Optionally includes identity, activity, and provenance sub-objects.
Example use cases
Pre-purchase risk screen for RPC tool
“I want to buy the QuickNode RPC health API via x402, but first check whether my agent is cleared to purchase it and what the risk level comes back as.”
Governance gate for autonomous agent spending
“My AI agent is about to spend USDC on an x402 API — run a preflight to verify the buyer identity fits the product category and price sensitivity before it goes through.”
Compliance check on Base network product
“Check the purchase governance for the QuickNode RPC health product on eip155:8453 — I need to see the risk score and any flags before approving the transaction.”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/quicknode/rpc-healthWhen to prefer
Use this endpoint when an AI agent needs to perform a pre-purchase governance check specifically for the QuickNode RPC health product on the Base (eip155:8453) network before committing an x402 USDC micropayment. Prefer it over generic identity or payment endpoints when you need a structured risk score and policy-flag assessment tied to a specific x402 product category and buyer role.
Side effects
- Missing or malformed endpoint_url query parameter returns a validation error
- endpoint_url does not match https?:// pattern causes schema rejection
- Product or endpoint not recognized in x402 catalog may return unknown product error
- Network unreachable or Cloudflare Worker timeout returns 5xx
- Buyer identity not resolvable may yield elevated risk_score or flags without blocking
