# AiFinPay > Payment infrastructure for autonomous AI agents — pay for services, charge for your API, over x402. ## Docs - [AiFinPay — Payment Infrastructure for AI Agents](https://docs.aifinpay.io/introduction.md): Stripe for autonomous AI agents. One line of code settles a real on-chain payment over HTTP, then returns the gated response. Non-custodial, multichain, token-free. - [Quickstart](https://docs.aifinpay.io/quickstart.md): From a clean machine to your first paid API call in under a minute. - [Node / TypeScript Quickstart](https://docs.aifinpay.io/pay/node.md): Build an AI agent that pays for APIs with @aifinpay/agent — generate a wallet, pay a URL, or let the SDK pick the best provider for a capability. - [Python quickstart](https://docs.aifinpay.io/pay/python.md): Build an AI agent that pays for gated APIs in Python with aifinpay-agent — generate a keypair, fund it, and call agent.pay(). - [Use AiFinPay from Claude (MCP)](https://docs.aifinpay.io/pay/mcp.md): Install the @aifinpay/mcp server so Claude can pay for AI services autonomously over x402 — no payment code required. - [x402 by hand](https://docs.aifinpay.io/pay/manual-flow.md): Implement the AiFinPay x402 payment flow without the SDK — the raw 402 challenge, the on-chain split payment, and the Ed25519 identity gate, step by step. - [Hosted Gateway — zero code](https://docs.aifinpay.io/charge/gateway.md): Put a payment gate in front of your existing API in about five minutes, entirely from the dashboard. No SDK, no bridge to host, no code changes. - [Self-serve dashboard](https://docs.aifinpay.io/charge/dashboard.md): Sign up, create a service, and start charging AI agents for your API in a few minutes — no bridge to run, no marketplace registry entry to file. - [Become a provider](https://docs.aifinpay.io/charge/onboarding.md): Charge AI agents per call by putting a config-only x402 bridge in front of your API — non-custodial, no contract to sign. - [Get discovered — Marketplace](https://docs.aifinpay.io/charge/marketplace.md): List your paid API in the AiFinPay catalog so agents you've never met can find it and pay. Publishing is separate from monetizing — your gate already works without it. - [Pricing, units and limits](https://docs.aifinpay.io/reference/pricing-and-limits.md): What a billing unit is, how tiers price a call, how free allowances and daily caps are counted, and what a receipt does and does not prove. - [Supported networks](https://docs.aifinpay.io/reference/networks.md): AiFinPay is live across 12 networks — 7 with the full smart-contract stack, plus splitter settlement on Optimism, BOT Chain, XRPL EVM, NEAR and Aptos. - [MCP Tools Reference](https://docs.aifinpay.io/reference/mcp-tools.md): The 7 tools exposed by @aifinpay/mcp — the agent payment + identity surface. (A read-only directory toolset is on the roadmap.)
