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-snapshot?utm_source=zero.xyz

When 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
