Endpoint

Choose this endpoint when you need real-time Amazon best-seller rankings without setting up an account or API key, and want to pay per call with USDC via x402. It is ideal for ad-hoc market research, price monitoring agents, or e-commerce intelligence workflows where Amazon product popularity data is needed on demand without a subscription commitment.
Side effects

- Amazon temporarily blocks or throttles scraping resulting in incomplete data
- Response schema may vary by category or be empty if Amazon changes its structure
- Payment failure via x402 protocol prevents request from completing
- Rate limiting if many requests are made in rapid succession
