# golfx402 — Frequently Asked Questions ## What is golfx402? golfx402 is an agent-native API and MCP server for booking and paying for golf tee times. AI agents and personal AI assistants use it to search availability, reserve a tee time, and pay automatically with the x402 payment protocol, powered by the TeeWire tee-time network. ## What is the x402 protocol? x402 is an open payment protocol built on the HTTP 402 "Payment Required" status code. A server responds with a 402 and machine-readable payment terms; an AI agent pays — typically with a stablecoin such as USDC — and retries the request to receive the result, with no human checkout. It was originated by Coinbase and is supported at the edge by Cloudflare and AWS. ## What is the Model Context Protocol (MCP)? MCP is an open standard, introduced by Anthropic, that lets AI assistants discover and call external tools and data in a consistent way. golfx402 runs an MCP server so any MCP-capable assistant can find and use its tee-time booking tools. ## How does an AI agent book a golf tee time? The agent calls golfx402 to search available tee times, chooses one, and requests a booking. golfx402 returns HTTP 402 with payment terms; the agent pays via x402 using a stablecoin wallet and instantly receives a confirmed reservation and booking reference. ## Do I need cryptocurrency to use golfx402? The x402 rail settles in stablecoins such as USDC, held in the agent's or app's wallet. End golfers using an AI assistant don't manage crypto directly — the app or agent handles settlement for them. Fiat on-ramps and alternative settlement options can be layered on by integrators. ## Who is golfx402 for? Three groups: AI app and agent developers who want tee-time booking in their product; golf courses and tee-time platforms that want their inventory bookable by agents; and golfers whose personal AI assistants book rounds for them. ## How much does golfx402 cost? golfx402 uses usage-based pricing: a per-booking fee settled through x402, or a metered plan for higher-volume partners. Because payment is native to the protocol, there's no invoicing or stored card to manage. ## Can third-party apps and personal AI assistants use it? Yes. golfx402 is API-first and MCP-native, designed for third-party golf booking apps, AI concierge products, and golfers' own personal AI assistants to integrate and pay per booking or via a usage plan. ## Does golfx402 work with platforms other than TeeWire? golfx402 launches on the TeeWire network and is designed as an open rail. Where it makes commercial sense, it can license agent-native access to other courses and competing tee-time platforms that want their inventory bookable and payable by AI agents. ## Is golfx402 the same as x402golf.com? Yes. golfx402.com is the primary site; x402golf.com points to the same product. --- *Home — · How it works — · Developers — · Courses — *
