How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream response from the Arkham Intelligence API, passed through after successful x402 micropayment verification. Typically includes entity labels, wallet attribution data, on-chain transaction history, or DeFi intelligence depending on the queried path.
Example use cases
Wallet entity attribution research
“Who owns the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045? Pull the entity labels and attribution data from Arkham for me.”
DeFi protocol treasury tracking
“I need to look up the on-chain holdings and recent transactions for the Uniswap treasury address on Arkham — can you fetch that data?”
Suspicious address investigation
“This address 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B just sent funds to my exchange — can you query Arkham to find out if it's linked to any known entities or flagged actors?”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/arkham?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-demand access to Arkham Intelligence blockchain analytics data without a direct Arkham subscription, and you want to pay per-query via the x402 USDC micropayment protocol. Ideal for agents that need occasional wallet attribution or entity lookups rather than high-volume continuous access.
Side effects
- Insufficient USDC balance causes payment failure and 402 response
- Invalid or unsupported Arkham API path returns 404 or upstream error
- Malformed JSON body results in upstream 400 bad request
- Arkham API rate limits triggered on the upstream side return 429
- x402 facilitator unavailable causes payment processing failure
- Missing or invalid query parameters produce empty or error responses from Arkham
