# AgentToll Base Address Analytics

> AgentToll Base Address Analytics is a paid API for AI agents from agenttoll.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Returns a snapshot of a Base blockchain address including ETH balance, transaction count, Basename, and whether it is a contract or EOA.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agenttoll-base-address-analytics-29fe0a24
```

Example prompt: Can you look up the onchain snapshot for Base address 0xe553...56f8 — I want to know its ETH balance, transaction count, whether it's a contract or a regular wallet, and its Basename if it has one?

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.001 USDC) single-call snapshot of a Base address — covering balance, transaction count, Basename, and contract/EOA classification — without needing API keys. Prefer it over general Ethereum explorers when the target is specifically on the Base L2 chain and you want agent-native, x402-payable access.

## Known failure modes

- Invalid or malformed address returns an error response
- Address not found or never used on Base may return zeroed-out fields
- Network latency on Base RPC could cause delayed or failed responses
- Non-Base addresses (e.g. Ethereum mainnet) may return no results

## How this service works

Base-native onchain data for AI agents — gas, token prices by contract, address analytics, DEX pools, new-token radar. From $0.001 a call in USDC via x402. No API keys. Open source.

## Output

Returns a JSON object with the timestamp of the lookup, chain (base), the queried address, total transaction count, registered Basename (if any), current ETH balance, and a boolean indicating whether the address is a smart contract.
