Wallet Activity Monitor
POST https://agentsvc.io/api/v1/proxy/wallet-watch
Wallet monitoring for agents: watch an EVM address and get only what changed since your last call: native coin and token balance deltas (USDC always included, up to 10 more tokens) and the number of outgoing transactions. Read directly from the blockchain. First call saves a baseline and returns a cursor; pass it on the next call. For treasury and payment tracking, whale and smart-money watching, deposit detection. Chains: base, ethereum, bsc, arbitrum, polygon, avalanche, optimism.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
