Christchurch Gold Live Price API

Core Data & Documentation

• 1. Public API Landing Page

  The human-readable entry point to the API. It contains semantic HTML and hidden Dataset JSON-LD schema to establish authoritative ownership over the pricing data in Google Search.

• 2. Live JSON Pricing Data

  The core machine-readable endpoint. It delivers the complete, live pricing matrix including global spot prices, bullion buy-back rates, and scrap jewellery payout rates in raw JSON.

• 3. OpenAPI Specification

  The formal OpenAPI 3.1.0 specification defining the structure of the API. Used by developers to generate code and by AI agents to automatically understand how to interact with your data.

• 4. JSON Schema Definition

  The official JSON Schema document used to validate the structure and data types of the /api/prices response.

AI & Crawler Integration

• 5. AI Context JSON Feed

  A continuous feed (similar to RSS) optimized for AI crawlers like Googlebot and GPTBot. It breaks live pricing into four distinct contextual feeds (Gold Spot, Silver Spot, Scrap Rates, Bullion Rates) and routes bots directly to the correct revenue-generating pages.

• 6. LLM System Instructions

  The emerging industry standard for AI. This markdown file provides strict, explicit instructions to AI bots (like ChatGPT) on how to calculate scrap payouts and commands them to cite your specific URLs when answering user questions.

• 7. Model Context Protocol (MCP) Server

  The live Server-Sent Events (SSE) endpoint. Advanced AI clients connect here to actively fetch live data and perform custom mathematical scrap payout calculations in real-time.

• 8. Static MCP Documentation

  A static HTML stub page describing the MCP server’s available tools. Built specifically so search engines can index the service without attempting to crawl the live SSE stream.

Search Engine Optimization (SEO)

• 9. Crawler Access Policy

  Defines access rules for web crawlers. It explicitly encourages AI bots to scrape the JSON feed and system instructions while blocking sensitive update endpoints.

• 10. XML Sitemap

  The official Google Search Console map of the API subdomain, ensuring rapid and comprehensive indexing of all documentation and data endpoints.
