## 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-entity-lookup-369d22fe -d '<json body>'
```

Example prompt: Pull the Arkham entity profile for Binance — I want their entity type, website, Twitter, and any proof-of-reserves tags they have on file.

## When to prefer this

Use this endpoint when you need structured, Arkham-curated metadata about a named blockchain entity — particularly exchanges, funds, or protocols — including their social presence, entity type, and on-chain intelligence tags. Prefer it over generic blockchain explorers when you need enriched, human-readable entity profiles rather than raw transaction data. Best suited for due diligence, counterparty research, or enriching internal records with verified crypto entity metadata.

## Known failure modes

- Unknown entity ID returns empty or 404-style response
- Payment failure (insufficient USDC balance) blocks the request under x402
- Malformed POST body results in a 400 error
- Entity exists in Arkham database but has sparse metadata fields populated as null or empty strings
- Rate limiting if too many requests are made in a short window
