Arkham labels blockchain addresses with the entities behind them and exposes holders, counterparties, transfers and portfolio data through its Intel API. Since 5 August 2026 the API accepts x402: an agent pays per request in USDC at request time, with no account or key (https://info.arkm.com/announcements/x402-on-arkham). Per-call prices vary by endpoint and are set in the 402 challenge. The x402 routes are on api.arkm.com and appear in the Coinbase x402 Bazaar. Listed in the curated x402 catalog of Coinbase for Agents (https://docs.cdp.coinbase.com/coinbase-for-agents/overview), so an agent connected to a Coinbase account can pay for it from its USDC balance. Label coverage is as reported by Arkham.
