## 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-address-enriched-lookup-1468919d -d '<json body>'
```

Example prompt: Can you look up the Ethereum address 0x28C6c06298d514Db089934071355E5743bf21d60 on Arkham and tell me what entity owns it, whether it's a contract, and any labels or tags associated with it?

## When to prefer this

Choose this endpoint when you need Arkham's proprietary entity attribution and labeling for a specific blockchain address — particularly when you need to identify whether an address belongs to a known exchange (like Binance), DeFi protocol, or other labeled entity, and when Arkham's proof-of-reserves tags and social profile links are valuable. Prefer this over generic block explorers when entity intelligence and categorization matter, not just raw transaction data.

## Known failure modes

- Invalid or malformed address returns an error response
- Unsupported chain identifier results in a lookup failure
- Address not found in Arkham database returns empty entity/label fields
- Rate limiting or payment failure via x402 protocol returns 402 or 429
- Network timeout on Arkham API side

## How this service works

Get enriched Arkham intelligence for an address. $0.40 per call.

## Output

Returns a JSON object containing: the chain and address, a boolean indicating if it's a smart contract, an arkhamLabel with a human-readable name, an arkhamEntity object with entity ID, name, type (e.g. 'cex'), and social/web links, a flag for whether it's a user address, and an array of populatedTags with IDs, ranks, chain, label text, and display parameters.
