Agent Wallet Watch

A pay-per-call API that gives any autonomous agent a real-time snapshot of any Base wallet:

• ERC-20 token balances (USDC and more; capped per product)
• Transaction direction labels (in / out / self)
• Explicit partial/provider-limited metadata when upstream data exceeds a cap or has additional pages
• No signup, no API key, no KYC — x402 micro-payment to agent wallet

Products

1 USDC Wallet Watch snapshot — up to 20 ERC-20 token balances and at most 10 recent transactions for one address.

5 USDC Wallet Watch Pro — up to 200 ERC-20 token balances and at most 100 recent transactions for one address.

Successful complete responses expose the address, network, fetch time, token balances, and transactions. Native coin balances are not included. If a provider returns more tokens, more transaction records, or another transaction page, the response includes partial: true, complete: false, provider_limited: true where applicable, field-level completeness flags, and sources/provider_errors.
