How to Verify a Record Before You Buy with Claude
Use Claude and ToolRouter to verify a record before buying. Confirm the edition, check market prices, and compare listings.
Tool
Confirm the exact edition, check current market depth, and compare sale listings before you commit to a collector-priced record. Start with `search_releases`, `identify_pressing`, `release_details`, `price_guide`, and `market_search` to get the raw material. Claude is strongest when the first pass needs collector judgment: which identifier actually matters, whether the edition looks right, and whether the current asking prices make sense.

Steps
Once connected (see setup above), use the Record Collector tool:
- State every clue you already have before the first run: set the artist, title, format, country, year, and any barcode, catalog number, or matrix text from the listing.
- Use `record-collector` to run `search_releases`, `identify_pressing`, `release_details`, `price_guide`, and `market_search` for the candidate edition.
- Ask Claude to compare the evidence and tell you whether the record is really the edition you think it is. Focus on identifiers, country and year, collector demand, copies for sale, and whether the current listings look overpriced or unusually weak.
- Turn the result into a buy or pass recommendation, price target, or collector note.
Example Prompt
Try this with Claude using the Record Collector tool
Use record-collector to verify a Blue Note copy I am considering. The seller says it is an original pressing and the sleeve shows catalog number BST 84159. Search the likely releases, identify the most plausible pressing, open the full release details, check the current price guide, and search the market for comparable copies. Tell me whether this is probably the right edition, what price range looks reasonable, and what clue I should ask the seller to confirm next.
Tips
- Use the catalog number or matrix text whenever possible because title and artist alone are rarely enough for collector decisions.
- Treat asking prices as market signals, not truth; low supply and bad seller metadata can distort the surface price picture.
- Ask Claude to separate hard identifier evidence from softer market interpretation before you commit to the buy.
