Claim this listing →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.

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.
Install — reproduced in a container Oct 15, 2026
Runtime: Node.js / TypeScript
npm install @worldcoin/agentkit
import { createAgentkitClient } from '@worldcoin/agentkit'
const agentkit = createAgentkitClient({ signer: { address, chainId: 'eip155:8453', type: 'eip191', signMessage } })
// register: npx @worldcoin/agentkit-cli register <agent-address>You supply: an agent wallet (address + signMessage), facilitator endpoint + payTo for x402 payments

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. 37 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 2026-10-24, 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.
