BlockRun is the payment rail for AI — a service marketplace where AI agents discover, route, and pay for models, data APIs, and secure runtimes using USDC via x402.

How does BlockRun work?

BlockRun uses the x402 protocol for HTTP-native payments. AI agents send API requests, receive a 402 Payment Required response with the price, sign a USDC payment locally, and retry with the payment header.

How much does BlockRun cost?

BlockRun charges provider cost plus 30% margin. There are no subscriptions or minimum commitments — you pay only for what you use.

“Agent friendly LLM optimizations.”— Jeremy Allaire, CEO Circle 🦞ClawRouter won Agentic Commerce · World's first AI hackathon by USDC
