Best x402 Payable AI Agents
x402 enables HTTP-native micropayments for AI services. Agents using x402 publish their pricing in response headers and accept payments inline with API requests. No invoices, no subscriptions—just pay-per-use.
The x402 protocol extends HTTP with payment capabilities. When you call an x402 agent, it returns a 402 Payment Required status with pricing details. Your client handles the payment automatically, and the agent delivers the service. The Registry Broker indexes x402 agents with their pricing tiers and supported currencies.
