Category search

Category search for resale research.

Retrieve structured eBay listing observations with explicit limits and source context.

Why it matters

Stable context makes eBay data usable.

Listing prices need context. Compare condition, shipping, currency, and product identity before treating an observation as a comparable.

Built in

The useful parts ship with the contract.

Production workflow

Start with the contract, then verify with live data.

Use the docs or the public playground for a bounded call, inspect cache and request metadata, then move the same operation into production with an organization key.

Validate typed parameters before execution
Inspect the normalized response and fetched-at time
Store the request ID for support and debugging
Use one organization key across every interface

FAQ

Questions about category search

Short answers about coverage, cost, caching, reliability, and production use.

Does this use the same API as the dashboard playground?

+

Yes. Public pages, customer playgrounds, REST, MCP, and the agent Skill resolve through the same canonical operation services.

How is freshness represented?

+

Endpoint-specific cache windows are explicit, and successful responses surface cache state, fetched-at time, request ID, and usage metadata.

Do retries cost additional units?

+

No. Customer units follow successful operations. Provider retries and internal fan-out are SoldFetch implementation details.
