    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Look up the recorded risk facts for one make, model and model year: NHTSA complaint counts by system and subsystem, recalls, investigations, manufacturer communications, an optional verified complaints-per-100k-sold rate and source coverage. Separately labeled Jev model tags (model years 2012 and newer; about 43 percent of all complaints are tagged) carry per-label counts, shares and model confidence, which is not accuracy. Spellings and aliases resolve to the stored vehicle. A zero is confirmed only when coverage_complete is true. These are observed records, not a prediction, safety rating, verdict, repair advice or an individual vehicle history.

  • compare_vehiclesCompare recorded facts for several vehicles side by side, with factual orderings by complaints, recalls and available verified complaints-per-100k-sold rates.No findings

    Why it is in this group

    • The name "compare_vehicles" says "compare": a word for reading.
    Description, as the server wrote it
    Compare recorded facts for several vehicles side by side, with factual orderings by complaints, recalls and available verified complaints-per-100k-sold rates. Unknown vehicles come back with database suggestions and unrated vehicles stay explicitly unrated. Counts reflect source coverage; no recommendation, verdict or safety ranking. The free tier compares up to 2 vehicles per call, paid plans up to 5.

    Annotations the server declares

    • title: Compare vehicles
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • listing_changesList observed dealer listing changes (new, price drop, relisted, delisted) with VIN, price, mileage, dates, source and link, filtered by vehicle, event type or date.No findings

    Why it is in this group

    • The description's first verb is "list": a word for reading.
    Description, as the server wrote it
    List observed dealer listing changes (new, price drop, relisted, delisted) with VIN, price, mileage, dates, source and link, filtered by vehicle, event type or date. Collector status separates an inactive feed from observed events. No photos or dealer-written text; delisted only means the listing was no longer observed, not that a sale completed. The free tier returns at most 10 events per call with no paging, paid plans up to 200 with cursors.

    Why it is in this group

    • The description's first verb is "list": a word for reading.
    Description, as the server wrote it
    List new and updated NHTSA recalls, investigations and complaint-count changes that this service recorded from the daily NHTSA bulk-file comparison, newest first, filtered by make, model, model year, type (recall, investigation, complaint_count) or observed date. Each change has the NHTSA campaign or action number, the record date, a short summary and a source link. These are published records, not a prediction, safety rating or advice. The free tier returns at most 10 changes per call with no paging, paid plans up to 200 with cursors and a vehicle watchlist.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
