Report Missing Functionality Tool

report_missing_functionality_tool

Full Description

This tool should be called ONLY if the user requests a CARFAX-specific feature that the server does not yet implement. Do NOT call this tool for generic requests unrelated to CARFAX or car shopping. The request will be logged and used for review to add future enhancements.

Parameters (1 required)

Required

requeststring

A brief description of the feature the user is requesting. Do NOT include any PII.

Search Multiple Makes Models For Sale

search_multiple_makes_models_for_sale

Full Description

Widen a vehicle search by including multiple makes/models or geographic areas.

Use this tool to broaden results when the user would consider several similar vehicles, wants to search across multiple locations, or both. Up to 5 searches per call. Returns up to 25 vehicles total across all searches.

Note, you must NOT mix used and new vehicles in the searches. If you do, the server will only return used vehicles, and you will get an indication in the return message.

Examples:

"best deal on a Civic, Corolla, or Mazda 3 near 22030" → 3 entries, same zip, different make/model
"Subaru WRX near St. Louis and Kansas City" → 2 entries, same make/model, different zip_code
"find me a WRX or GTI along my road trip route" → entries with different make/model AND zip_code

Each entry accepts the same fields as the single-search tool (zip_code, radius, make, model, etc.). When a sort order is specified, results are ranked across all searches by that criteria. Otherwise, results are interleaved round-robin from each search.

Returns: dict: Combined search results from all searches.

Parameters (1 required)

Required

searchesarray

List of search parameter sets. Each entry is an independent search with its own make, model, zip_code, radius, and filters. Use multiple entries to compare different vehicles OR to search the same vehicle across different locations.
