How this service works
Get Arkham contract intelligence. $0.20 per call.
Output
A JSON object containing the contract's address, proxy status, bytecode (may be empty), deployment transaction hash and timestamp, the deployer's address with Arkham entity and label details (name, type, social links), the proxy implementation address if applicable, and any function signature hashes. Arkham entity data includes the organization name, type (e.g. stablecoin), website, Twitter, LinkedIn, and Crunchbase links.
Example use cases
Identify DeFi protocol deployer
“I found this contract address 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D interacting with my wallet — can you use Arkham to tell me who deployed it and which organization is behind it?”
Proxy contract investigation
“Can you check if the contract at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on Ethereum is a proxy contract and, if so, what the underlying implementation address is according to Arkham?”
Smart contract due diligence
“Before I interact with this contract, can you pull the Arkham intelligence record for 0x6B175474E89094C44Da98b954EedeAC495271d0F — I need the deployer entity, deployment date, and any known labels associated with it?”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/intelligence/contractWhen to prefer
Choose this endpoint when you need Arkham's proprietary entity-resolution intelligence on a specific smart contract — particularly when you want to identify the real-world organization behind a contract, check proxy relationships, or get deployment provenance. Prefer this over generic block explorers (Etherscan, etc.) when entity labeling and organizational attribution matter, not just raw on-chain data.
Side effects
- Unknown or unindexed contract address returns empty or null entity fields
- Invalid address format causes a 400 bad request
- Contract not yet crawled by Arkham returns partial data with null labels
- Payment failure via x402 returns 402 Payment Required
- Non-contract (EOA) address may return unexpected results or an error
- Unsupported chain returns an error or empty response
