# CatalogAPI > Global rewards and gift card API. Browse a catalog of over two million gift cards, prepaid cards, and merchandise across 120+ countries, build a cart, place an order, and track fulfillment through one integration. Every page below serves markdown to a request that sends `Accept: text/markdown`. ## Start here - [API documentation](https://api.catalogapi.com/api/docs): Every endpoint, parameter, and model, across catalogs, carts, orders, and fulfillment. Ask for markdown and this index links a separate page per endpoint, model, and guide, so you can fetch the one operation you need instead of the whole API. - [Authentication](https://api.catalogapi.com/auth.md): API keys, not OAuth. A person creates the key; an agent cannot mint one. - [AI agent integration guide](https://api.catalogapi.com/developers/ai-agents): First call in minutes: copy-paste curl, and a prompt that scaffolds an integration. - [Pricing](https://api.catalogapi.com/pricing): Pay on redemption. No monthly fee and no long-term commitment. ## Ask us directly An assistant can query the live catalog instead of reading about it. - [MCP server card](https://api.catalogapi.com/.well-known/mcp/server-card.json): Read-only MCP server at /mcp (streamable-http, no API key). Tools: check_coverage, search_rewards, get_reward_details, how_it_works.
