Decode vehicle identification numbers into year, make, model, trim, engine, drivetrain, safety equipment and the matching catalog entry. action=decode takes `vin` (and optionally `year` to override the model year). action=batch takes `vins`, at most 50, and returns one result per VIN in order. A wrong check digit is not an error: the result has valid=false and a warning. action=overview takes `vin

Look up vehicles by year, make, model, submodel and engine. Actions: years; makes (optional `year`); models (`make`, optional `year`); submodels (`make`, `model`, `year`); engines (`make`, `model`, `year`, optional `submodel`); search (`query`, such as "2019 civic si" or "chevy 1500"); entry (`id`, such as "2019_honda_civic_si"); overview (`id`: everything held for that model year in one answer, w

Recall campaigns from NHTSA (United States) and Transport Canada that may apply to a vehicle. A campaign lists a year, a make and a model, so every answer has may_apply: true. It may apply; confirm by VIN with the manufacturer, or at the addresses in `lookup`. This is never a lookup by VIN. action=vehicle takes `id`, a vehicle id such as "2018_ford_f-150". action=vin takes `vin` (and optionally `y

Manufacturer communications NHTSA publishes: service bulletins, service campaigns, warranty extensions and over-the-air updates. Each has NHTSA's summary, the manufacturer's own document number, and `document`, the address NHTSA's copy of the document is expected at (not confirmed; null for old ones). The document itself is the manufacturer's and is not returned. A bulletin lists model years: it i

Generic OBD-II trouble codes, described in Wenmar Open's own words: a title, what the code means, common causes, first checks, the components it concerns and related codes. Only codes every maker uses the same way are described (P0, P2, P3400 and up, B0, C0, U0, U3). Manufacturer-specific codes are not described. action=get takes `code`, such as "P0420", and gives its description. action=search li

Wenmar's own estimates of the hours a repair job takes: written by people who do the work and later measured from repair orders, never from a labour guide. An estimate, not a quote. Rust, seized fasteners and added equipment change the time. action=jobs lists the jobs an estimate can be about; with `job` it gives one job: what it includes, what it excludes, and its typical hours by class of vehicl
