eBay API solution questions
What can I actually build with an eBay data API?
The five recipes on this page cover the workflows SoldFetch customers build today: price monitoring, product research, listing quality, seller intelligence, and bounded tools for AI agents. Each page maps the job to the relevant SoldFetch operations, parameters, and production considerations.
Do I need a different API key for each eBay marketplace?
No. One SoldFetch key covers all 3 data operations across enabled marketplaces. Pass the documented marketplace code so currency, locale, eBay host, and delivery context stay explicit on every request.
Are these separate products with separate pricing?
No. They are the same SoldFetch described by customer job. A successful normalized operation consumes one unit, while provider retries and failed operations do not silently add usage.
How do I pick between a solution page and an API page?
Start from a solution when you know the outcome you need, and from the API directory when you already know the exact operation. Solution cards link to their operation set, and every detailed solution includes an implementation path.
Can one product combine several of these solutions?
Yes. Production workflows often combine sold search, category search, and item details. Shared authentication, response metadata, errors, and normalized contracts keep the downstream integration consistent.
Can AI agents use the same SoldFetch operations?
Yes. REST, MCP tools, and the installable ebay-data Skill resolve through the same 3 bounded operations, validation rules, quotas, and authorization model.
