What is Ecommerce Data API?
Amazon product, keyword, market, sales estimate, review, traffic, and trademark data flow through Ecommerce Data API using REST endpoints and a remote Model Context Protocol server. Developers building research workflows or connecting AI agents query the system using authentication headers such as X-API-Key or Authorization: Bearer. Requests accept JSON payloads specifying marketplace regions and target ASINs, returning structured attributes like pricing, categories, BSR ranks, star ratings, seller counts, and historical snapshots.
Endpoint groups and research filters
The 46 available endpoints divide into specialized groups covering product searches, ASIN details, category nodes, price history, paginated reviews, BSR sales predictions, coupon activity, and competitor records. Keyword endpoints handle search demand, reverse lookups, traffic statistics, and weekly or monthly Amazon Brand Analytics metrics. Additional routes provide market analysis for category concentration, traffic source flows, global trademark records, and optical character recognition for images. Each route supplies response JSON schemas alongside request examples for languages and libraries like LangChain and the OpenAI Responses API.
Authentication, MCP, and usage limits
New accounts receive five free test calls valid for three days after email verification. Beyond the trial, users select from one-time credit packs valid for 60 days or monthly subscription tiers including Starter, Pro, and Business plans. The dashboard manages API key generation, revocation, and real-time usage monitoring. The remote MCP server integrates directly into coding assistants and chat interfaces using OAuth 2.1 with PKCE authentication.
