# Arkham Intelligence: Full Address Profile

> Arkham Intelligence: Full Address Profile is a paid API for AI agents from api.arkm.com, paid per call via x402, $0.4/call, status unknown (last checked 2026-09-14).

Returns comprehensive on-chain intelligence for a blockchain address, including entity identification, labels, chain type, and contract status via Arkham's wallet intelligence database.

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-full-address-profile-04748b87 -d '<json body>'
```

Example prompt: Look up 0x28C6c06298d514Db089934071355E5743bf21d60 on Arkham — tell me what entity owns it, whether it's a contract, and any social or exchange links associated with it.

## When to prefer this

Use this endpoint when you need the richest available on-chain identity profile for a single address — entity classification, social links, and Arkham labels all in one call. Prefer this over simpler ENS or block-explorer lookups when you need to know whether an address belongs to an institution (exchange, fund, protocol) rather than just resolving a name. Best for compliance checks, due diligence, transaction monitoring enrichment, and investigative blockchain research.

## Known failure modes

- Address not found in Arkham database — entity and label fields may be null or absent
- Invalid or malformed blockchain address returns an error response
- Payment failure via x402 if USDC balance is insufficient
- Unsupported chain type may return no data for that chain key
- Rate limiting if many requests are made in rapid succession

## How this service works

Get Arkham intelligence for an address across all chains. $0.40 per call.

## Output

A JSON object keyed by chain name containing: the address, a boolean contract flag, an Arkham label object (human-readable name and chain type), and an Arkham entity object with the entity's ID, name, type (e.g. 'cex', 'fund'), note, Twitter, website, LinkedIn, and Crunchbase URLs. Also includes an isUserAddress flag.
