Endpoint
POSThttps://quanta-roan.vercel.app/api/service/serp-ebay-productWhen to prefer
Use this endpoint when you need programmatic access to eBay product search results with per-call micropayment billing via x402 and no subscription required. Ideal for agents that need occasional or bursty eBay search queries without a full API key setup, or for web3-native workflows that prefer on-chain micropayments.

- Upstream eBay SERP service unavailable or rate-limited
- Invalid or missing query parameters resulting in empty results
- Malformed JSON body causing request parsing errors
- No results found for the given search query
- Gateway timeout if the upstream search provider is slow
