Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-address-batch-intelligence-99797863 -d '<json body>'
```

Example prompt: Can you look up these three Ethereum addresses for me — 0x28C6c06298d514Db089934071355E5743bf21d60, 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B, and 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE — and tell me which entities or exchanges Arkham Intelligence has labeled them as?

## When to prefer this

Choose this endpoint when you need to resolve multiple blockchain addresses to real-world entities in a single API call, saving cost and round-trips compared to single-address lookups. Ideal for compliance workflows, on-chain investigation, or enriching transaction data at scale. Prefer Arkham specifically when you need curated entity intelligence including exchange attribution, social profiles, and organizational metadata — not just raw on-chain data.

## Known failure modes

- Invalid or malformed address returns no entry or error for that address
- Unrecognized or unlabeled address returns minimal data with no arkhamEntity or arkhamLabel
- Insufficient USDC balance or x402 payment failure results in request rejection
- Exceeding batch size limits may result in partial responses or errors
- Network timeout if too many addresses are submitted simultaneously

## How this service works

Fetch Arkham address intelligence in batch. $50.00 per call.

## Output

A JSON object keyed by input address, each containing the chain name, contract flag, Arkham label (e.g. 'Hot Wallet'), and full Arkham entity metadata including entity ID, name, type (e.g. 'cex'), and social/web links (Twitter, website, LinkedIn, Crunchbase). Also includes an isUserAddress flag.
