Endpoint
POSThttps://serp402.com/api/v1/amazon-autocomplete?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, structured Amazon keyword autocomplete data without managing API keys, subscriptions, or accounts. It is ideal for keyword research, Amazon SEO, PPC campaign building, and competitive analysis across multiple Amazon international domains and departments. Prefer this over general web scraping when you specifically need Amazon's own autocomplete signal.
Side effects
- Invalid or unsupported Amazon domain returns an error or empty result
- Unsupported department code returns an error or falls back to all departments
- Empty or very short keyword string may return no suggestions
- Payment failure (insufficient USDC balance) blocks the request
- Rate limiting or Amazon-side blocking may cause transient failures
