# ProofKit > ProofKit is a pay-per-GB VPN on TON: no monthly plan, a non-custodial escrow people withdraw from, and one link that carries five transports (VLESS Reality, Hysteria2, XHTTP, WebTunnel and olcRTC, shaped like a video call). Anyone can run a node and be paid for it. This file is a map of the site for assistants: the pages for operators, partners and users, and the two MCP servers. ## Operators - [Run a node](https://proofkit.org/operators): what running a ProofKit node involves, where the network needs nodes, what an operator earns, and the path from sign-up to the first payout. - [Operator docs](https://proofkit.org/operator-docs): the quick start, connecting an AI agent, the API reference, what each node check means, and how payouts work. - [Operator API explorer](https://proofkit.org/operator-api): every endpoint of the Operator API (OpenAPI 3.1) with its parameters, answers and error codes, and a console to call them with an operator key. - [Operator MCP server](https://proofkit.org/mcp/operator): manage your nodes from ChatGPT, Claude, Claude Code, Cursor, Codex or VS Code: sign in to connect, or send an operator key (Authorization: Bearer pko_...) from a script. - [Nodes wanted](https://proofkit.org/api/v1/operator/wanted): where the network needs nodes right now, as JSON; public, no key. ## Partners - [Partner program](https://proofkit.org/partners): resell ProofKit's VPN under your own brand, with a subscription link for each subscriber and prices per GB prepaid in TON. - [Partner docs](https://proofkit.org/partner-docs): the quick start, the API reference, paying in TON, the dashboard without code, and AI assistants. - [Partner API explorer](https://proofkit.org/partner-api): every endpoint of the Partner API (OpenAPI 3.1) with its parameters, answers and error codes, and a console to call them with a partner key. - [Partner MCP server](https://proofkit.org/mcp/partner): manage a partner account from an AI assistant: sign in to connect. ## Users - [ProofKit](https://proofkit.org/): a pay-per-GB VPN on TON with five transports in one link for heavy blocking, WebTunnel and one shaped like a video call among them; no monthly plan. Top up with TON from a wallet of your own and withdraw what you don't use. - [Help center](https://proofkit.org/help): connecting a client, choosing a transport, deposits, per-GB billing, withdrawals, and running a paid node. - [Network](https://proofkit.org/network): a live map of the network: where the nodes are, the traffic between them, exit countries and route prices.
