## 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-search-api-bfcd1ccc -d '<json body>'
```

Example prompt: Search Arkham for the entity or address '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045' and tell me which named entity or label it belongs to.

## When to prefer this

Choose this endpoint when you need to resolve or identify blockchain addresses, entities, tokens, or pools using Arkham Intelligence's proprietary labeled dataset. It is especially useful for on-chain attribution — finding out who controls a wallet — or discovering all addresses associated with a named entity like an exchange or protocol. Prefer this over generic block explorers when entity-level labeling and intelligence context matters.

## Known failure modes

- Empty results if the address or entity name is not indexed in Arkham
- Payment failure if $6 USDC is not available or x402 payment protocol fails
- Malformed request if required body fields are missing or incorrectly formatted
- Rate limiting or access denial if the endpoint quota is exceeded

## How this service works

Search Arkham addresses, entities, tokens, pools, and names

## Output

Returns a list of matching results from Arkham's intelligence database, which may include blockchain addresses with entity labels, token metadata, liquidity pool details, and named wallet identifiers associated with the search query.
