How to Build an Agent Marketplace: The Technical Architecture

说明与用途

完整自动化的代理市场架构：机器可读列表、x402 程序化支付、通过证明链实现信任以及在 Base 上即时 USDC 结算。

问题

Traditional marketplaces assume human buyers, but agent marketplaces require machine‑readable listings, programmatic payments, automated verification, and instant settlement.

结果

The architecture enables a fully automated agent marketplace with discoverable services, programmatic payments, trust via proof chains, and instant crypto settlement.

工作流

• 1. Publish a registry of services as agents.json with schema.org ItemList and offer details.
• 2. Providers register via /registry/register, supplying name, description, endpoint, price, and capabilities; the system validates the endpoint, generates llms.txt and agents.json, and indexes the service.
• 3. Each provider receives x402 middleware that intercepts requests, verifies receipts, tracks usage for commissions, proxies to the provider’s endpoint, and logs a proof chain entry.
• 4. Proof chains are appended for every transaction, enabling agents to verify provider integrity before paying.
• 5. Agents crawl the registry, query services, and use the x402 payment flow to transact automatically.
• 6. Settlement occurs instantly in USDC on Base, eliminating net‑30 delays.

证据

Agents don’t browse. They crawl.
