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.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden.
Last 30 days — to 2026-11-07, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
