Etsy Open API v3, B (63.4)\n\nEtsy's Open API v3 is a REST API for the Etsy marketplace. Any approved app can search active listings across all shops with an API key, while OAuth covers seller shop, listing and order management. Public OpenAPI 3.0 contract and keyed listing search across all Etsy shops, with price, keyword, category and location filters and documented 429 handling. It is search only. No cart, checkout, buyer order or return endpoints exist, so a person buys on etsy.com, and cross-shop use needs a reviewed Personal App.\n\n- Page: https://www.anchorterminal.com/tools/etsy · Markdown: https://www.anchorterminal.com/tools/etsy.md · JSON: https://www.anchorterminal.com/api/v1/tools/etsy.json\n- Capabilities: shopping.search, shopping.prices · endpoint: `https://api.etsy.com/v3`\n\n### 862.

Read-only product search and lookup across 22 Amazon stores, with field selection, typed error reasons and documented rate limits.

It also finds nearby retailers by postal code. Two compact MCP tools and a small REST API with structured errors let an agent turn a list into an Instacart cart link.
