Steps
Once connected (see setup above), use the Marketplace Search tool:
- Describe the item, including any model variants or regional naming differences you know about.
- Run `source_coverage` to identify active marketplaces, then `search_listings` across all available sources.
- Have ChatGPT summarize the results with a focus on authenticity indicators, condition, and which sources are worth rechecking later.
Example Prompt
Try this with ChatGPT using the Marketplace Search tool
Use marketplace-search to find a Technics SL-1200 MK2 turntable in Europe. Check source coverage, search all available sources, and summarize the best matches with notes on whether they appear to be original units or reissues.
Tips
- Ask ChatGPT to flag listings with vague photos or generic descriptions as lower-confidence matches.
- Request a follow-up search plan with alternative terms if the first pass returns few results.
