# BlockRun

> BlockRun is the payment rail for AI — a service marketplace where AI agents discover, route, and pay for APIs using USDC via the x402 protocol. No API keys required.

BlockRun provides pay-per-request access to 30+ large language models (GPT-5, Claude, Gemini, Grok, DeepSeek, Kimi, Llama, Mistral, and more), image generation APIs, and real-time data services including neural web search (Exa), X/Twitter intelligence, and prediction markets (Predexon). AI agents pay with USDC on Base or Solana — no subscriptions, no API keys, no vendor lock-in.

## Key Products

- [ClawRouter](https://blockrun.ai/clawrouter): Smart LLM router that cuts API costs up to 78% via 7-layer compression, intelligent model routing, and response caching. Open source, MIT licensed.
- [AI Model Gateway](https://blockrun.ai/models): Access 30+ LLMs from OpenAI, Anthropic, Google, xAI, DeepSeek, Moonshot, Meta, Mistral, Cohere, Alibaba via a single OpenAI-compatible endpoint.
- [Data Marketplace](https://blockrun.ai/partners): Neural web search (Exa), real-time X/Twitter data, prediction markets (Predexon), and more — AI agents buy data the same way they buy compute.
- [Claude Code Plugin](https://blockrun.ai/claude-code-plugin): Use BlockRun services directly from Claude Code.

## For Developers

- Python SDK: `pip install blockrun-llm`
- TypeScript SDK: `npm install @blockrun/llm`
- Go SDK: `go get github.com/blockrunai/blockrun-llm-go`
- MCP Server: `claude mcp add blockrun --transport http https://mcp.blockrun.ai/mcp`

## How It Works

BlockRun uses the x402 protocol — an HTTP-native payment standard. When an AI agent makes an API request, BlockRun returns a 402 Payment Required response with the price. The agent signs a USDC payment locally (private key never leaves the agent's machine), retries the request with the payment header, and receives the response. Settlement is non-custodial and instant.
