x402 Foundation Members & Ecosystem Map

By Cleared · Updated August 2026 · 6 min read

The x402 Foundation launched under the Linux Foundation in April 2026. By July, 40+ organizations had joined — spanning payments, cloud infrastructure, AI, crypto, and traditional finance. This is the most comprehensive map of who's building the agent payment layer and where trust verification fits.

The Missing Layer: Trust & Verification

Look at the ecosystem above. You have protocol governance (Foundation), settlement (Coinbase, Circle, Stripe), infrastructure (AWS, Cloudflare, Vercel), identity (World), and agent frameworks (Anthropic MCP). But there's a gap:

Who verifies that an endpoint is safe to pay before the agent sends money?

That's Cleared Index. We're the trust layer that sits between discovery and payment. Agents call our API, get a deterministic trust score, and decide whether to proceed. Think of it as the SSL certificate for x402 endpoints — you don't pay a website that doesn't have one, and agents shouldn't pay endpoints that haven't been verified.

For Foundation Members & Ecosystem Builders

If you're building on x402 — whether you're a facilitator, an agent framework, a wallet provider, or a service operator — here's how Cleared fits your stack:

Facilitators

Pre-verify endpoints before settling payments. Reduce failed settlements and chargebacks.

Agent frameworks

Add a trust gate to your agent's payment flow. 3 lines of code. Under 200ms.

Wallet providers

Show trust scores before spending. Protect users from unverified endpoints.

Service operators

Get listed, get verified, get discovered. Agents find you via Cleared before they pay.

Integrate Cleared Into Your Stack

Free API. Public methodology. Under 200ms response. Works with any x402 implementation.
