# Arkham Intelligence Batch Address Enrichment

> Arkham Intelligence Batch Address Enrichment is a paid API for AI agents from api.arkm.com, paid per call via x402, $200/call, status unknown (last checked 2026-09-14).

Batch-enriches multiple blockchain wallet addresses with Arkham intelligence, returning entity labels, CEX/DEX attribution, contract flags, and tagged metadata for each address.

## Facts

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-intelligence-batch-address-enrichment-27f6cadd -d '<json body>'
```

Example prompt: Can you look up these Ethereum addresses — 0x28C6c06298d514Db089934071355E5743bf21d60, 0xabc123... — and tell me what entities own them, whether they're contracts, and any exchange or proof-of-reserves tags Arkham has on them?

## When to prefer this

Use this endpoint when you need to enrich a batch of blockchain addresses simultaneously with Arkham's proprietary entity intelligence — particularly when you need CEX attribution, entity names, contract classification, and wallet tags in a single call. Prefer this over single-address lookups when processing multiple addresses at once to save on per-call costs. Ideal for compliance workflows, on-chain investigation, or portfolio counterparty analysis where entity identity is needed at scale.

## Known failure modes

- Invalid or malformed Ethereum address returns no entry or error for that address
- Rate limiting or payment failure if x402 payment of $200 USDC is not properly attached
- Unrecognized address with no Arkham coverage returns minimal metadata (no entity or label)
- Batch too large may result in timeout or partial response
- Network errors from the Arkham API backend

## How this service works

Programmatic access to Arkham wallet intelligence and market data — via API keys and x402 pay-per-request.

## Output

A JSON object keyed by input address, where each value contains: chain metadata, a boolean contract flag, an Arkham label (wallet-level name), an Arkham entity object (org name, type like 'cex', social/website links), an isUserAddress flag, and an array of populated tags (e.g. proof-of-reserves) with rank and chain context.
