# How golfx402 works > golfx402 combines three open standards: **MCP** for discovery, a **tee-time API** for inventory, and **x402** for payment. Together they turn "find me a tee time" into a completed, paid reservation with no human checkout. ## The agent booking flow, step by step 1. **Discover the MCP server.** An AI assistant that speaks the Model Context Protocol (MCP) finds golfx402 in the MCP registry and loads its tools — `search_tee_times`, `hold`, `book`, `cancel`. This makes golfx402 usable by any MCP-capable assistant without custom glue code. 2. **Search live inventory.** The agent queries the golfx402 tee-time API for real availability across the TeeWire network — filtering by course, date, number of players, and price. 3. **Request a booking.** The agent requests a reservation on the golfer's behalf. golfx402 responds with **HTTP 402 Payment Required**, describing the amount due and the accepted stablecoin — the machine-readable equivalent of a checkout page. 4. **Pay via x402.** The agent settles with a stablecoin wallet using the x402 protocol and automatically retries the request with proof of payment. No card entry, no redirect, no human. 5. **Receive confirmation.** golfx402 confirms the tee time and returns a booking reference the assistant can show the golfer. Done in one automated round-trip. ## Why x402 and MCP together? **MCP** solves discovery and interface — it's how an AI assistant knows golfx402 exists and how to call it. **x402** solves settlement — it's how the agent pays for a booking in the same HTTP round-trip, with no human. Neither alone is enough for autonomous commerce; together they turn "find me a tee time" into a completed, paid reservation. This is the same pattern the broader agentic-commerce ecosystem is converging on, now that Cloudflare and AWS support x402 payments at the edge. | Standard | Role | |----------|------| | **MCP** | Discovery & interface. An open standard from Anthropic. Any MCP-capable assistant can find golfx402 and call its booking tools with no per-integration wiring. | | **x402** | Payment & settlement. An open protocol on HTTP 402. The agent pays in stablecoins in the same request cycle — no invoicing, no stored card, no checkout page. | --- *Next: developer integration — · Full FAQ — *
