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.
Example use cases
Identify unknown whale wallet
“I've been tracking a large Ethereum wallet — 0xabc123... — that keeps moving millions around. Can you look it up on Arkham and tell me who or what entity is behind it, and whether it's linked to any known exchange or fund?”
Due diligence on counterparty address
“Before we send funds, can you check if 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE is a known entity on Arkham? I need to know if it's a CEX hot wallet, a contract, or something else.”
Enrich transaction alert with entity context
“We just got an alert that 0xDA9dfA130Df4dE4673b89022EE50ff26f6EA73Cf sent a huge transfer — can you pull the Arkham label and entity info for that address so I know if it's a market maker, exchange, or unknown actor?”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/intelligence/address-allWhen to prefer
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.
Side effects
- 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
