Tools: vehicle_risk compare_vehicles listing_changes recall_changes
vehicle_risk | 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 confide params: make*, model*, year* |
compare_vehicles | 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 params: vehicles* |
listing_changes | 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 wi params: make, model, year, vin, event_type, since, until, limit, cursor |
recall_changes | 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, no params: make, model, year, type, since, until, limit, cursor |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
