# Build with AI Documentation
> Entry point for building with AI on Quicknode. Routes each goal to a tool: Build Web3 plugin for coding agents, Quicknode MCP for live blockchain data and account management, CLI and SDK for account management, x402 and MPP for keyless access, Agent Subscriptions for agent-created accounts, and llms.txt for documentation discovery. Explains the three access models: API key, agentic payments, and agent subscriptions.

- [Build with AI](https://www.quicknode.com/docs/build-with-ai.md): Entry point for building with AI on Quicknode. Routes each goal to a tool: Build Web3 plugin for coding agents, Quicknode MCP for live blockchain data and account management, CLI and SDK for account management, x402 and MPP for keyless access, Agent Subscriptions for agent-created accounts, and llms.txt for documentation discovery. Explains the three access models: API key, agentic payments, and agent subscriptions.
- [Agent Subscriptions](https://www.quicknode.com/docs/build-with-ai/agent-subscriptions.md): Create a Quicknode account and subscription programmatically using x402 or MPP payments. Receive a full platform API key and provision RPC endpoints without human signup.
- [Agentic Payments](https://www.quicknode.com/docs/build-with-ai/agentic-payments.md): Quicknode supports two wallet-based payment protocols, x402 and MPP, for one-shot RPC calls or to programmatically create a Quicknode account via Agent Subscriptions.
- [Build Web3 Plugin](https://www.quicknode.com/docs/build-with-ai/build-web3-plugin.md): Agent plugin for AI coding assistants. One install adds the build-web3 skill and the Quicknode MCP server, which reads live blockchain data and manages the account. The skill plans, builds, and repairs Web3 apps on EVM, Solana, and Hyperliquid. It covers use cases, architectures, chains, stacks, starter code, and security. It contains a reference file for each Quicknode product (Streams, SQL Explorer, RPC, Webhooks, Solana gRPC, Hypercore, IPFS, Key-Value Store, Admin API, SDK, CLI, x402, MPP, Agent Subscriptions). Install commands for Claude Code, Codex, Cursor, and other agents.
- [LLM-Optimized Docs](https://www.quicknode.com/docs/build-with-ai/llms-txt.md): Quicknode publishes llms.txt indexes so AI tools and LLMs can discover and reason about Quicknode's full developer resource library, including RPC methods, developer tooling, guides, sample apps, and ecosystem documentation.
- [MPP Payments](https://www.quicknode.com/docs/build-with-ai/mpp-payments.md): Access Quicknode's blockchain infrastructure with pay-per-request stablecoin payments using the MPP protocol. No account or API keys required.
- [Quicknode APIs](https://www.quicknode.com/docs/build-with-ai/quicknode-apis.md): Quicknode's blockchain APIs are standard HTTP endpoints that any AI agent or LLM-powered application can call directly for RPC, data pipelines, storage, and account management.
- [Quicknode MCP](https://www.quicknode.com/docs/build-with-ai/quicknode-mcp.md): Query live blockchain data and manage Quicknode infrastructure through natural language, using the official MCP server with any compatible AI assistant.
- [x402 Payments](https://www.quicknode.com/docs/build-with-ai/x402-payments.md): Access Quicknode's blockchain infrastructure with wallet-authenticated, pay-per-request stablecoin payments using the x402 protocol. No account or API keys required.
