## What it does

Balance of any EVM address on Base, Ethereum, Arbitrum, Optimism or Polygon \(or all 5\): native coin and native USDC \(atomic + decimal\), transaction count \(nonce\), whether it is a contract or an EIP-7702 delegated EOA, explorer link. Live from public RPC. Returns the full, untrimmed result as JSON. A free public MCP at https\://orbit-chain.orbit-builder.workers.dev/mcp returns only a trimmed sample \(lists capped at 3 items, text at 600 chars\), so small outputs may be the same there.

## How to buy

```text
PAID ($0.001/call): call_service({ id: "svc_353e80a4-755f-4ced-8727-35a9662331a2", args }) — the 402 lists ONE x402 payment = the FULL price straight to the seller (FiatDock takes 0% of this listing's calls right now); the fiatdock-mcp npm package (AGENT_PRIVATE_KEY) pays it automatically. This remote /mcp returns the 402 challenge. You are charged only if the seller actually answers. To learn what to put in arguments, call get_service({ id: "svc_353e80a4-755f-4ced-8727-35a9662331a2", includeSchemas: true }) first — it returns toolSchemas (argument names and types). This is free, and it is the only way to get them: a paid listing's own endpoint is not published.
