Price: 10 credits

List the VIN deciphering guides and manufacturer identification filings manufacturers submitted to NHTSA, newest first, with a link to each document.

How to use it

Use it to get a manufacturer's own VIN decoding guide when nhtsa/vins cannot decode a VIN, or to see when a manufacturer registered with NHTSA. `url` opens the filed document.

Parameters

• access-token string required

Request body

• timeout integer — Max scrapping execution timeout (in seconds) (default: 300; min: 20; max: 1500)
• part_type string required — vin_decoding for VIN deciphering guides (49 CFR 565), manufacturer_identification for manufacturer identification filings (49 CFR 566) (one of: "vin_decoding", "manufacturer_identification"; examples: "vin_decoding")
• from_date string nullable — Keep filings dated on or after this day (format: date; examples: "2015-01-01")
• to_date string nullable — Keep filings dated on or before this day (format: date; examples: "2015-12-31")
• manufacturer string nullable — Keep filings of manufacturers whose name contains this text (examples: "honda"; minLength: 1)
• count integer required — Max number of results (min: 1)

Response

• @type string (default: "NhtsaPart")
• id string required
• part_type string nullable (one of: "vin_decoding", "manufacturer_identification")
• letter_date string nullable
• manufacturer_id string nullable
• manufacturer_name string nullable
• model_year_from integer nullable
• model_year_to integer nullable
• url string nullable
• cover_letter_url 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 — The entity was not found, or a precondition failed 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.
