GET STARTED
Fund your AI,
it handles the rest
Give your AI a budget. It discovers what services to use—models, data, APIs. When the budget runs out, it stops.
How it works
What your AI can access
LLM calls
GPT-5, Claude, Gemini, Grok, DeepSeek—all major models on demand.
Market data
Sentiment analysis, trading signals, real-time intelligence.
Content creation
Image generation, optimized social posts, media tools.
Any x402 service
Pay-per-use APIs. Your AI discovers and uses them automatically.
Integration
Install as MCP server for Claude Code or Antigravity
claude mcp add blockrun -- npx @blockrun/mcpOpenCode AI plugin for agentic payments
{ "plugin": ["@blockrun/opencode"] }Integrate directly into Python agents and scripts
pip install blockrun-llmIntegrate directly into TypeScript/Node.js projects
npm install @blockrun/llmRecommended Budget
Start small. $1-5 USDC on Base is enough for most experimentation.
Common Questions
What is x402?
x402 is an HTTP-native payment protocol. When your AI requests a service, it receives an HTTP 402 response with payment details. Your agent signs a USDC transaction, attaches it to the request, and gets the service. All in one round-trip—no accounts, no API keys.
What is MCP?
MCP (Model Context Protocol) is Anthropic's standard for connecting AI assistants to external tools. BlockRun's MCP server gives Claude Code and other compatible AI tools the ability to discover and pay for services autonomously.
Why USDC on Base?
Base is an Ethereum L2 with low fees (~$0.001 per transaction) and instant finality. USDC is a stablecoin pegged to USD, so your AI's budget stays predictable. Together, they enable micropayments that would be impossible on Ethereum mainnet.
Is my private key safe?
Yes. Your private key never leaves your machine. The SDK signs transactions locally using EIP-712 typed data. BlockRun servers only see the signed transaction—never your key.
What happens when my budget runs out?
Your AI stops making paid requests. It's a natural spending limit. Add more USDC when you're ready to continue. No surprise bills, no overages.
Can I use this without crypto knowledge?
Yes. The SDK handles wallet creation and transaction signing automatically. You just need to fund with USDC on Base—most exchanges support direct withdrawals to Base.
