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 detected address kind (wallet or token), a numeric risk_score (0-100), a risk_level label (e.g. 'low'), an alpha_score indicating opportunity, a trade_bias recommendation (e.g. 'watch'), a next_action guidance string, machine-readable tags, and for tokens: symbol, 24h volume, and liquidity in USD — all scoped to the Base (EIP-155:8453) network.
Example use cases
Example prompt
“Before my agent sends any USDC, can you run an alpha risk score on this Base address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — auto-detect whether it's a wallet or token and tell me the risk level, alpha score, and what action to take next?”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/base/alpha-riskWhen to prefer
Use this endpoint when an AI agent needs to pre-screen a Base network wallet or ERC-20 token address for risk before executing an autonomous payment or DeFi interaction. Prefer this over generic blockchain explorers when you need a structured risk score, alpha signal, and actionable trade bias in a single call scoped specifically to the Base L2 network.
Side effects
- Invalid or malformed address (not matching 0x[40 hex chars] pattern) returns a 400 validation error
- Address not found or insufficient on-chain data may return incomplete scores or an error
- Rate limiting or budget exhaustion may return 402 Payment Required
- Cloudflare Worker timeout if upstream data sources are slow
- Token with very low liquidity may produce unreliable alpha_score
