## 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-updates-2fa3dd27 -d '<json body>'
```

Example prompt: Pull the latest Arkham address label updates on Arbitrum One — give me newly labeled wallets and entity names that have changed since January 1, 2025, starting from the beginning of the feed.

## When to prefer this

Choose this endpoint when you need to incrementally sync or monitor Arkham's address intelligence database — specifically to detect newly labeled wallets, updated entity attributions, or new token/DEX tags across chains. Prefer it over static lookups when your use case requires staying current with Arkham's labeling as it evolves, or when building a local mirror of Arkham's address data. It is paginated and cursor-driven, making it suitable for bulk ingestion pipelines.

## Known failure modes

- Invalid or expired pageToken returns an error or resets pagination
- Missing or invalid API key / x402 payment returns 402 or 401
- Requesting an unsupported chain returns empty results or an error
- Payment of less than $20 USDC rejected by x402 facilitator
- Rate limiting if too many requests are sent in quick succession
- Network timeout on large paginated result sets
