a2a-agent
BlockRun is the routing and payment layer for AI. One OpenAI-compatible endpoint routes to 87 LLMs plus image, video, music and speech generation, web search, prediction-market and on-chain data, and multi-chain RPC. Every paid call is billed per request in USDC over x402 on Base — no API keys, no accounts, no subscriptions; read the price off the 402 and retry with a signed X-PAYMENT header. 7 open-weight chat models are free and need no wallet.
