Amazon price tracker API
Watch prices without a browser extension. Track Amazon products on a schedule and build a price history with the lowest, highest and average price, stock, seller and price-drop alerts — then compare every seller's offer on Google Shopping and research the Amazon keywords shoppers type.
From $0.01 per product check · no API key · failed calls refunded
What you get
- Current Amazon price, list price, stock and seller
- Lowest, highest and average price over time

Which Amazon marketplaces are supported?+
Set the marketplace on each call — Amazon US, UK, Germany and the other major storefronts.
How is the price history built?+
Each scheduled check is stored, so the lowest, highest and average prices grow more useful the longer you track a product.
Do I need a E-commerce API key or developer account?+
No. Sourcelane runs the connectors for you. You top up a balance with a card, create an agent key, and your agent calls the connector — there is no E-commerce app review, OAuth setup or rate-limit juggling on your side.
Which AI tools can use it?+
Anything that speaks MCP (Claude Desktop, Claude Code, Cursor, VS Code, Windsurf) can connect to the Sourcelane MCP server with one config block. ChatGPT can use it through a Custom GPT Action, and any agent framework can call the REST endpoint directly.
Can I stop an agent from overspending?+
Yes. Every agent key has its own per-call cap, daily and monthly limits, an optional lifetime budget, an allowlist of connectors, and a kill switch.
