Overview
World AgentKit, announced March 2026 in partnership with Coinbase, is a developer SDK (in limited beta) that lets an AI agent present a zero-knowledge proof derived from its owner's World ID, confirming a unique verified human delegated authority without revealing personal data. It pairs identity with the x402 stablecoin micropayment protocol and integrates server-side as middleware for Hono, Express, and Next.js, exposing OpenAI- and Anthropic-tool-compatible functions. Payment rails run on Base.

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. 49 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. Rates spanning that date mix two definitions. Since then: 100%.

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.
