README

BlockRun LLM SDK (Python)

**blockrun-llm** is a Python SDK for accessing 80+ large language models (GPT-5.x, Claude 4.x, Gemini 3.x, DeepSeek, Grok 4.x, GLM, MiniMax, Moonshot and more) plus image / video / music generation, Grok Live Search, prediction-market data (Predexon), Exa neural web search, and Pyth-backed market data. Every call is paid per request — no subscription, no seats, no minimum. Built for AI agents that need to operate autonomously.

**Two ways to pay, same SDK, same catalogue.** Sign up at **[user.blockrun.ai](https://user.blockrun.ai)** for an API key and prepaid credit (top up with a card), or hold USDC in your own wallet and let each request settle itself over x402 — on **Solana or Base**. Every client takes either credential in the same first argument.

🆓 **Includes 8 fully-free NVIDIA-hosted models** — DeepSeek V4 Flash (1M context), Nemotron Nano Omni (vision), Qwen3 Next + Coder, Llama 4 Maverick, Mistral Small 4, plus `gpt-oss-120b/20b` (hidden from `/v1/models` but direct calls still work). Zero USDC, no rate-limit gimmicks. Use `routing_profile="free"` or call any `nvidia/*` model directly.

**BlockRun assumes Claude Code as the agent runtime.**
