How this service works
Get enriched Arkham intelligence for an address. $0.40 per call.
Output
Returns a JSON object containing: the chain and address, a boolean indicating if it's a smart contract, an arkhamLabel with a human-readable name, an arkhamEntity object with entity ID, name, type (e.g. 'cex'), and social/web links, a flag for whether it's a user address, and an array of populatedTags with IDs, ranks, chain, label text, and display parameters.
Example use cases
Identify unknown wallet counterparty
“I just received funds from 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe on Ethereum — can you use Arkham to tell me what entity or exchange this address belongs to and whether it's flagged with any known labels?”
Compliance screening for crypto transfers
“Before I process this withdrawal, can you check if the destination address 0xA090e606E30bD747d4E6245a1517EbE430F0057e on Ethereum is associated with a known exchange, sanctioned entity, or flagged with any Arkham tags?”
Research CEX proof-of-reserves addresses
“I'm building a report on Binance's on-chain reserves — can you pull the Arkham enriched data for address 0x28C6c06298d514Db089934071355E5743bf21d60 on Ethereum and show me its entity info, labels, and any proof-of-reserves tags?”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/intelligence/address-enrichedWhen to prefer
Choose this endpoint when you need Arkham's proprietary entity attribution and labeling for a specific blockchain address — particularly when you need to identify whether an address belongs to a known exchange (like Binance), DeFi protocol, or other labeled entity, and when Arkham's proof-of-reserves tags and social profile links are valuable. Prefer this over generic block explorers when entity intelligence and categorization matter, not just raw transaction data.
Side effects
- Invalid or malformed address returns an error response
- Unsupported chain identifier results in a lookup failure
- Address not found in Arkham database returns empty entity/label fields
- Rate limiting or payment failure via x402 protocol returns 402 or 429
- Network timeout on Arkham API side
