# Arkham x402 Search

> Arkham x402 Search is a paid API for AI agents from api.arkm.com, paid per call via x402, $6/call, status down (last checked 2026-09-16).

Search Arkham's blockchain intelligence database to resolve entities, wallets, tokens, ENS names, and market data in one call

## Facts

- Endpoint: POST https://api.arkm.com/x402/search
- Price: $6/call
- Payment: x402
- Status: down
- Last checked: 2026-09-16
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/arkham-x402-search-125374ef
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ekmZhr0qO6wGbfmA9eK-v

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-x402-search-125374ef -d '<json body>'
```

Example prompt: Search Arkham for everything known about 'Binance' — give me their labeled wallet addresses, token prices, associated ENS names, and any linked Twitter or OpenSea accounts.

## When to prefer this

Choose this endpoint when you need a single unified lookup that resolves a name, address, or token across Arkham's full intelligence graph — covering entity labels, wallet addresses, token prices, ENS, OpenSea, and Twitter simultaneously. Prefer it over on-chain RPC calls when you need human-readable entity attribution, or over CoinGecko/CMC when you need both market data AND wallet identity in one call. Best suited for blockchain investigators, DeFi researchers, and compliance agents that need to enrich an address or entity name with maximum context.

## Known failure modes

- Ambiguous query returns matches across many unrelated entities requiring further filtering
- Unknown entity or address returns empty arrays for all categories
- Payment failure via x402 protocol results in 402 response before any data is returned
- Rate limiting or quota exceeded returns an error response
- Query for a very new token or address not yet indexed returns no results

## How this service works

Search Arkham addresses, entities, tokens, pools, and names. $6.00 per call.

## Output

A JSON object containing matched results across multiple categories: arkhamEntities (named entities like exchanges with type and Twitter), arkhamAddresses (labeled wallet addresses with chain and label), ENS records, token price data (current price, 24h ago price, deployments per chain), DeFi pool data (price, liquidity, market cap, volume), OpenSea profiles, and Twitter accounts — all keyed to the search query.
