## 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 arkham-intelligence-contract-lookup-62459628 -d '<json body>'
```

Example prompt: Can you look up the Arkham intelligence profile for the contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — I want to know who deployed it, whether it's a proxy, and what entity is behind it?

## When to prefer this

Choose this endpoint when you need Arkham's proprietary entity-resolution intelligence on a specific smart contract — particularly when you want to identify the real-world organization behind a contract, check proxy relationships, or get deployment provenance. Prefer this over generic block explorers (Etherscan, etc.) when entity labeling and organizational attribution matter, not just raw on-chain data.

## Known failure modes

- Unknown or unindexed contract address returns empty or null entity fields
- Invalid address format causes a 400 bad request
- Contract not yet crawled by Arkham returns partial data with null labels
- Payment failure via x402 returns 402 Payment Required
- Non-contract (EOA) address may return unexpected results or an error
- Unsupported chain returns an error or empty response

## How this service works

Get Arkham contract intelligence. $0.20 per call.

## Output

A JSON object containing the contract's address, proxy status, bytecode (may be empty), deployment transaction hash and timestamp, the deployer's address with Arkham entity and label details (name, type, social links), the proxy implementation address if applicable, and any function signature hashes. Arkham entity data includes the organization name, type (e.g. stablecoin), website, Twitter, LinkedIn, and Crunchbase links.
