How this service works
EOA vs contract, ETH + USDC balance, transaction count and activity level — straight from Base RPC. Useful for counterparty and wallet checks. Paid via x402: $0.01 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.
Output
Returns a structured profile of the queried Base address including: whether it is an EOA or smart contract, current ETH balance, current USDC balance, total transaction count, and an activity level indicator — all sourced directly from Base RPC.
Example use cases
Example prompt
“Can you check the on-chain profile for Base address 0xAbC123...? I want to know if it's an EOA or contract, its ETH and USDC balances, and how active it's been.”

Endpoint
POSThttps://api.relai.fi/relay/1782567677091/api/x402/address-intelWhen to prefer
Use this endpoint when you need a quick counterparty check on a Base wallet — specifically to distinguish EOA from contract, verify ETH/USDC holdings, or gauge wallet activity level before a transaction or integration. Prefer this over full blockchain explorers when you need a lightweight, programmatic, single-call summary rather than full transaction history.
Side effects
- 402 Payment Required — must pay $0.01 USDC on Base to 0x973a31858f4d2125f48c880542da11a2796f12d6 and retry
- Invalid address format — address does not conform to EIP-55 checksummed format
- Address not found / zero activity — valid address with no on-chain history returns zeroed fields
- RPC timeout — Base RPC node unavailable or slow, resulting in a 503 or timeout error
- Rate limiting — too many requests without valid payment headers
