Rye Universal Checkout

Rye's Universal Checkout API turns any product URL into a completed purchase. You provide a product URL and buyer info — Rye handles pricing, tax, shipping, and order placement across merchants (Shopify, Amazon, and thousands more).

The Product Data API complements checkout by letting you look up product details (price, availability, images, description) from any URL before committing to a purchase.

When to use this skill

Two primary use cases:

1. Integrate (B2B/Developer) — A developer wants to add purchasing capabilities to their app (marketplace, shopping assistant, dropshipping tool, gifting platform, etc.)
2. Buy (Agent Commerce) — An AI agent needs to programmatically purchase a product on behalf of a user
