BlockRun AI Gateway

Other
BlockRun is the routing and payment layer for AI. One OpenAI-compatible endpoint routes to 71 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, batched through Circle Gateway and settled on Polygon, Arbitrum One, OP Mainnet, Unichain, Avalanche, Sonic, Sei Network, World Chain, HyperEVM, Ethereum, Arc — no API keys, no accounts, no subscriptions; read the price off the 402 and retry with a signed X-PAYMENT header. 4 open-weight chat models are free and need no wallet. **Discovery probes:** every paid endpoint accepts the header `X-402-Discovery: 1` (or query `?discover=1`), which short-circuits straight to the canonical 402 challenge with default pricing — no body parse, no schema validation. Use this from registries / aggregators to fetch the exact 402 shape without sending a valid request body.
