Claim this listing →Overview
Chainbase markets itself as a 'Hyperdata Network' that turns onchain signals into structured, AI-ready data, reporting coverage of 200+ blockchains. It exposes data to AI agents via API, a CLI, an MCP integration, and packaged Agent Skills, with x402 support. Coverage figures and 'verifiable' claims are self-reported by Chainbase; Chainbase also has an associated token.

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. 38 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
Last 30 days — to 2026-10-23, 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.
