How this service works
Total transaction count, first & last activity timestamps, and wallet age in days for any Base address. Built for sybil/rug screening and counterparty trust checks. Paid via x402: $0.01 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.
Output
A JSON object containing the total number of transactions the wallet has made, the timestamp of its first on-chain activity, the timestamp of its most recent on-chain activity, and the wallet's age expressed in days — all sourced from the Base blockchain.
Example use cases
Example prompt
“Can you pull the wallet summary for 0xAbC123...def on Base — I want to know how old it is, how many transactions it's made, and when it was last active so I can decide if it's safe to deal with?”

Use this endpoint when you need a quick, cheap ($0.01) sybil/trust check on a specific Base (eip155:8453) wallet address and want structured age, transaction count, and activity window data — especially useful before executing a DeFi transaction or airdrop eligibility check where counterparty trust matters.
Side effects

- Invalid or malformed Base address returns an error
- Address has no on-chain activity — may return zeros or nulls for timestamps
- Network or relay timeout on api.relai.fi
