## 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-entity-intelligence-summary-7069c88b -d '<json body>'
```

Example prompt: Pull the Arkham entity summary for Binance — I want to see their total on-chain balance, cumulative volume, number of addresses, and when their first and last transactions were.

## When to prefer this

Choose this endpoint when you need a quick aggregate snapshot of a known named blockchain entity (exchange, fund, protocol, whale) — covering balance, volume, address count, and activity timestamps — without needing individual transaction-level detail. Ideal for due diligence, counterparty research, or competitive analysis where the entity is already labeled in Arkham's intelligence database. Prefer this over raw blockchain explorers when you need enriched, entity-level aggregation rather than raw address data.

## Known failure modes

- Unknown or unrecognized entity ID returns an error or empty result
- Payment failure due to insufficient USDC balance causes request rejection
- Malformed entity ID string results in a 400 bad request
- Rate limiting or quota exceeded returns a 429 error
- Entity exists but has no indexed data returns zeroed fields
