{"name":"BlockRun","description":"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 Solana (Solana) — no API keys, no accounts, no subscriptions; read the price off the 402 and retry with a signed X-PAYMENT header. Open-weight chat models are free and need no wallet.","url":"https://sol.blockrun.ai/api/v1","provider":{"organization":"BlockRun, Inc.","url":"https://sol.blockrun.ai"},"version":"1.0.0","protocolVersion":"0.3.0","documentationUrl":"https://sol.blockrun.ai/llms.txt","capabilities":{"streaming":true,"pushNotifications":false,"stateTransitionHistory":false},"defaultInputModes":["application/json"],"defaultOutputModes":["application/json","text/event-stream"],"securitySchemes":{"x402":{"type":"apiKey","in":"header","name":"X-PAYMENT","description":"x402 payment signature; see the 402 response for requirements."}},"security":[{"x402":[]}],"skills":[{"id":"chat","name":"Chat & LLM routing","description":"OpenAI-, Anthropic-, Gemini- and Responses-compatible chat across frontier and open-weight models.","tags":["llm","chat","routing"],"examples":[]},{"id":"media","name":"Image, video, music, speech","description":"Generation endpoints priced per call.","tags":["image","video","audio","tts"],"examples":[]},{"id":"search","name":"Web & neural search","description":"Live web/X search and Exa neural search + page extraction.","tags":["search","exa"],"examples":[]},{"id":"markets","name":"Prediction & crypto markets","description":"Prediction-market data, on-chain and price feeds.","tags":["polymarket","kalshi","crypto"],"examples":[]},{"id":"rpc","name":"Multi-chain RPC","description":"JSON-RPC for 40 chains through one paid endpoint.","tags":["rpc","ethereum","solana"],"examples":[]},{"id":"payments","name":"Pay per call in USDC on Solana","description":"x402: 402 challenge → signed exact USDC authorization → retry.
