How to Build an Agent Marketplace: The Technical Architecture

Описание и применение

Архитектура полностью автоматизированного рынка агентов: машинно‑читаемые листинги, программные платежи через x402, доверие через цепочки доказательств и мгновенное расчёт в USDC на Base.

Задача

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

Результат

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

Рабочий процесс

• 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.
