How this service works
Address Fingerprint: agent-usable x402 brief at 0.02 USDC on Base. Base address balance/activity/contract check.
Output
Returns a JSON object containing: a boolean success flag, a numeric risk score, a human-readable summary, a confidence string (e.g. 'high'/'medium'/'low'), an evidence object with supporting on-chain data, an array of strengths, an array of risk factors, and an ISO-8601 generatedAt timestamp. Also includes payment metadata indicating transaction details.
Example use cases
Pre-payment wallet safety check
“I want to pay this address 0x4fB7a8C9...Dd on Base — can you quickly check if it looks safe, give me a risk score, and tell me if it's a contract or a regular wallet?”
DeFi counterparty due diligence
“Before I approve this DeFi transaction with 0x9eA2...F3c, run a fingerprint on that Base address and let me know its activity level, any red flags, and how confident you are in the assessment.”
New user wallet vetting
“A new user just signed up and gave us their Base wallet 0xD1F8...99a — can you score and summarize their address to see if there's anything suspicious in their on-chain history?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/address-fingerprintWhen to prefer
Choose this endpoint when you need a quick, structured risk profile of a Base blockchain address before executing a payment, onboarding a user, or interacting with an unknown counterparty. It is particularly useful for x402 payment agents that need to pre-screen recipient addresses. Prefer this over generic blockchain explorers when you need a scored, agent-consumable output rather than raw transaction data.
Side effects
- Missing or invalid 'address' query parameter returns an error response
- Non-Base or malformed address strings may return low-confidence or error results
- Payment failure or insufficient USDC balance blocks access to paid response
- Rate limiting or upstream Base RPC unavailability may cause timeouts
- Newly created addresses with no history may return minimal evidence and low confidence scores
