Output
A JSON object containing the address risk verdict (safe/risky/unknown), risk score, contract vs EOA classification, transaction count, ETH balance, flags for brand-new or dormant wallets, proxy contract detection, and on-chain behavioral signals — all cryptographically signed with Ed25519 for independent verification.
Example use cases
Example prompt
“Before I send 500 USDC to 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD, can you run a risk check on that address — I want to know if it's a contract or regular wallet, how active it is, and whether it's flagged as high risk?”
Technical details
Endpoint
POSThttps://obol-x402.fly.dev/v1/evm/address/:addressWhen to prefer
Choose this endpoint when an AI agent needs to assess counterparty risk before executing a payment or approving a transaction on Base — especially when you want on-chain behavioral signals (activity level, contract type, dormancy, proxy detection) combined into a single risk verdict. Prefer this over generic blockchain explorers when you need a machine-readable safety score rather than raw blockchain data.
Side effects
- Invalid or malformed EVM address returns a 400 error
- Address not found or never used on Base may return minimal data or a new-wallet flag
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Network or RPC issues fetching on-chain data may result in a 503 or timeout
- Ed25519 signature verification failure if the response was tampered in transit
