How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output

Example use cases
Used electronics price check
“Search eBay for used MacBook Air M2 laptops and tell me what prices people are currently listing them for.”
Collectibles marketplace search
“Look up eBay listings for vintage 1980s Star Wars action figures — I want to see what's available and how much they're going for.”
Reseller inventory scouting
“Search eBay for Nike Air Jordan 1 Retro sneakers in size 10 and pull back the current listings so I can compare prices.”

Endpoint
POSThttps://quanta-roan.vercel.app/api/service/serp-ebay?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live eBay marketplace search results and want to pay per call with USDC via the x402 protocol rather than managing a traditional API key subscription. Ideal for agents that perform occasional or bursty eBay lookups without committing to a monthly API plan.
Side effects
- Payment failure if insufficient USDC balance — returns 402 Payment Required
- Invalid or malformed query parameters result in empty or error response
- eBay upstream API rate limiting or downtime causes 502/503 passthrough errors
- Missing required path or query fields return a generic proxy error
- Network timeout from upstream eBay service
