Overview

Quicknode provides tools for AI agents, coding assistants, and LLM-powered applications to interact with blockchain infrastructure. These tools include wallet-authenticated endpoint access, natural language infrastructure management, coding agent skills, and machine-readable documentation indexes.

x402 Payments

x402 Payments enables autonomous agents and developers to access Quicknode's blockchain infrastructure without an account or API keys. Any client that holds a wallet with USDC can authenticate via the x402 protocol and start making requests across all supported networks immediately.

The payment model works on a credit system: authenticate with your wallet, pay USDC to receive a credit bundle, then consume those credits across requests. When credits run out, the next request triggers another payment automatically, keeping agent workflows uninterrupted.

Quicknode MCP

Quicknode MCP (Model Context Protocol) lets you manage your Quicknode infrastructure through natural language. Instead of navigating the dashboard, you can create endpoints, monitor usage, configure security settings, and manage your account through any MCP-compatible AI assistant, including Claude Code, Codex, Claude Desktop, and Cursor.

Blockchain Skills

Blockchain Skills gives AI coding agents accurate, up-to-date knowledge of Quicknode's product suite. Without it, agents may generate incorrect API parameters, use outdated method names, or miss Quicknode-specific patterns.

Adding Skills to your agent takes a single command and provides the right endpoints, correct parameters, and current best practices without bloating the context window.

LLM-Optimized Docs

Quicknode publishes LLM-optimized docs (llms.txt files) indexes across multiple parts of the platform. These give LLMs a structured way to discover the right content for any blockchain development question, from RPC methods and infrastructure guides to sample apps and courses.
