Decode a World Manufacturer Identifier into its manufacturer, make and vehicle type.

How to use it

Use it to tell who built a vehicle from the first characters of its VIN when a full VIN decode is not needed. Pass 3 characters for most manufacturers; a manufacturer building fewer than 1,000 vehicles a year is identified by 6.

Parameters

• access-token string required

Request body

• timeout integer — Max scrapping execution timeout (in seconds) (default: 300; min: 20; max: 1500)
• wmi string required — World Manufacturer Identifier: the first 3 VIN characters, or 6 for small manufacturers (examples: "1HG")

Response

• @type string (default: "NhtsaWmi")
• wmi string required
• manufacturer_id string nullable
• manufacturer_name string nullable
• common_name string nullable
• parent_company_name string nullable
• make string nullable
• vehicle_type string nullable
• country string nullable
• url string nullable
• created_date string nullable
• updated_date string nullable
• public_date string nullable

Errors

• 422 — The request body did not validate Check the fields against this schema. A URN with the wrong prefix is the most common cause.
• 408 — The request ran past its time limit Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.
• 412 — No manufacturer is registered for this WMI Retrying will not help: either the entity does not exist, or the input points at a different one.
• 429 — Too many requests: a rate limit or a usage window is exhausted When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.
• 500 — Something broke on our side Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.
• 529 — Rate limit reached, or the endpoint is overloaded Wait at least 30 seconds, then retry.

Response headers

• X-Error — Error message text (present only on error)
• X-Request-ID — Unique request identifier
• X-Execution-Time — Execution time in seconds
• X-Result-Count — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.
• X-Total-Available-Results — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.
• X-Warning — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.
• X-Retry-After — Seconds to wait before retrying. Present only on 429.
