Endpoint
POSThttps://blackbobs-ai.vercel.app/api/ebay-average-selling-priceWhen to prefer
Choose this endpoint when you need real-time eBay-specific average selling prices based on completed transactions. Prefer this over general product search APIs when you need actual transaction data rather than listed asking prices, and when the use case is resale pricing, arbitrage research, or competitive benchmarking on the eBay marketplace specifically.
Side effects
- Product not found or no recent completed listings available
- Ambiguous or too-generic query returns unreliable averages
- Rate limiting or API quota exceeded
- Payment failure via x402 prevents request from being fulfilled
- Schema mismatch if query structure is not properly formed
