Price: 20 credits

List the plants registered with NHTSA to make tires, brake hoses, glazing or retreaded tires, with their DOT plant code, address and status.

How to use it

Use it to find which factory a DOT code on a tire, hose or window belongs to, or to track plants that opened, changed or closed in a year. Take report_type all for the whole register; one DOT code can appear on more than one plant row for brake hoses, glazing and retread.

Parameters

• access-token string required

Request body

• timeout integer — Max scrapping execution timeout (in seconds) (default: 300; min: 20; max: 1500)
• equipment_type string required — Kind of equipment the plant makes (one of: "tires", "brake_hoses", "glazing", "retread"; examples: "tires")
• report_type string required — Plants registered new, updated or closed in the given year, or the whole register (one of: "new", "updated", "closed", "all"; examples: "new")
• year integer required — Year of the registration change; with report_type all the whole register is returned (examples: 2024; min: 1900; max: 2100)
• count integer required — Max number of results (min: 1)

Response

• @type string (default: "NhtsaEquipmentPlant")
• dot_code string required
• old_dot_code string nullable
• name string nullable
• address string nullable
• city string nullable
• state_province string nullable
• postal_code string nullable
• country string nullable
• status 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.
