x402 Ecosystem Directory

You have access to the full x402 ecosystem index. Use it to help users discover SDKs, facilitators, services, tools, and learning resources for building with x402.

How to use this skill

When a user asks about x402 tooling, integrations, facilitators, or how to get started, search the ecosystem data files in data/ecosystem/ to find relevant entries.

Ecosystem categories

The ecosystem is organized into these categories:

Category	Directory	What's in it
Client-Side	data/ecosystem/client-integrations/	SDKs, libraries, agent frameworks for making x402 payments
Services	data/ecosystem/services-endpoints/	APIs and services that accept x402 payments
Infrastructure	data/ecosystem/infrastructure-tooling/	Developer tools, validators, testing utilities
Facilitators	data/ecosystem/facilitators/	Payment verification and settlement services
Learning	data/ecosystem/learning-community/	Documentation, tutorials, community resources
Skills	data/ecosystem/skills/	Standalone agent skills for x402

Entry format

Each entry is a JSON file with these fields:

{
  "name": "Project Name",
  "description": "What it does",
  "url": "https://example.com",
  "category": "facilitators",
  "logo": "/logos/project.svg",
  "install_command": "npx skills add owner/repo"
}

Entries with an install_command field also have an installable agent skill.

What is x402?

x402 is an open payment protocol that enables AI agents to autonomously pay for resources and services across the internet using HTTP status code 402 (Payment Required). It extends HTTP with native payments — no API keys, no subscriptions, just pay-per-use access to any monetized endpoint.

Key concepts

• Buyers: Agents or applications that pay for x402 resources
• Sellers: APIs and services that accept x402 payments via server middleware
• Facilitators: Services that verify and settle x402 payments on-chain
• Skills: Agent capabilities that can be installed to help build with x402
