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
A JSON object containing the network identifier (eip155:8453), product name (base-token-alpha-snapshot), and an assessment object with a numeric risk_score, a risk_level string (e.g. 'low'), and an array of flags indicating any detected issues with the token.
Example use cases
Example prompt
“Before my agent sends payment, can you run a risk snapshot on the Base token at address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA and tell me if it's flagged or what its risk score is?”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/base/token-alpha-snapshotWhen to prefer
Use this endpoint when an AI agent needs a fast, pre-payment risk check on a specific ERC-20 token on the Base network before executing a transaction. Prefer this over generic block explorers when you need a structured, machine-readable risk score and flag set specifically designed for autonomous agent payment workflows.
Side effects
- Missing or malformed token address (not a valid 0x... 40-hex-char address) results in a 400 or validation error
- Token address not found or not indexed on Base returns empty or default assessment
- Payment not provided or x402 payment rejected returns 402 Payment Required
- Rate limiting or worker timeout returns 429 or 5xx
- Token exists but has no on-chain activity, resulting in minimal signal and a zero risk score with empty flags
