# Heurist Mesh – ChainbaseAddressLabelAgent

> Heurist Mesh – ChainbaseAddressLabelAgent is a paid API for AI agents from mesh.heurist.xyz, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Retrieves all available labels for an Ethereum or Base blockchain address, including owner identity, smart contract names, wallet behavior patterns, and ENS/Base name resolution.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 heurist-mesh-chainbaseaddresslabelagent-b186fe1f -d '<json body>'
```

Example prompt: Can you look up all the labels and identity info for the Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — tell me who owns it, whether it's a smart contract, any ENS names, and any wallet behavior tags?

## When to prefer this

Choose this endpoint when you need to enrich or identify an Ethereum or Base blockchain address with human-readable labels, owner identity, contract metadata, or behavioral tags — especially when ENS/Base name resolution is also needed in the same call. Prefer over raw block explorers when you need structured, agent-consumable label data rather than raw transaction history.

## Known failure modes

- Address not found or no labels available returns an empty label set
- Invalid 0x address format causes a request validation error
- Address exists but has no on-chain history or labels returns minimal or null results
- Network or Chainbase data source unavailability causes a timeout or 5xx error
- Payment failure via x402 protocol blocks request execution

## How this service works

Get all available labels for an ETH or Base 0x address. Labels may describe owner identity, smart contract name, wallet behavior patterns and other properties. Also resolves ENS and Base names if available.

## Output

A set of labels for the queried address, which may include the owner's identity (e.g. exchange name, known individual, DAO), the smart contract name and protocol if applicable, wallet behavior tags (e.g. high-frequency trader, mixer usage), and resolved ENS or Base name if one exists.
