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 with the Base network identifier (eip155:8453), the product name, and an assessment object containing a risk_level string (e.g. 'low', 'medium', 'high'), a numeric risk_score, and an array of flags describing any detected risk signals. May also include activity, identity, and provenance objects with additional context about the token.
Example use cases
Pre-purchase agent safety check
“Before the agent spends any funds on that new Base API listing, run an exit risk check on the token address 0x4200000000000000000000000000000000000006 — I need to know the risk level and any flags before approving the transaction.”
DeFi token rug pull screening
“Can you evaluate the exit risk for this Base ERC-20 token 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA? I want to see if it has a low, medium, or high risk score before I let any automated agent interact with it.”
Automated x402 purchase governance
“My agent is about to use x402 to pay for a dataset, but first check the exit risk on the payment token at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base and tell me if there are any risk flags I should know about.”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/base/token-exit-riskWhen to prefer
Use this endpoint when an AI agent needs a lightweight, fast preflight risk check on a Base ERC-20 token before executing an x402 micropayment or purchase. Prefer it over generic token screeners when operating within the Base/x402 ecosystem and needing a structured risk_level and flags output suitable for automated governance decisions.
Side effects
- Invalid or malformed token address (not matching 0x[40 hex chars] pattern) returns an error
- Token address not found on Base network returns unknown or empty assessment
- Network timeout from Cloudflare Workers returns a 5xx error
- Token with no on-chain history may return empty flags but indeterminate risk level
