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.
Example use cases
Identify unknown wallet owner
“I just received a large transaction from 0x00000029fF545c86524Ade7cAF132527707948C4 — can you search Arkham to find out who owns this address and what entity it's associated with?”
Entity on-chain footprint research
“Search Arkham for all on-chain information about FTX — I want their labeled bitcoin and ethereum addresses, any associated tokens, and their CEX service profile.”
Token market data and pool lookup
“Look up the token 'beth' on Arkham and get me its current price, 24-hour price change, contract addresses across chains, and any liquidity pools it's trading in.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/searchWhen to prefer
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.
Side effects
- 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
