}Preview — Vehicle Model Detection
Tool to identify the make, the model and the version of a vehicle from a photo.
- Allows you to recognize the make and the model of a vehicle from its silhouette and its badging.
- Proposes to narrow the result down to the generation and the body style.
- Offers the possibility of returning several candidate models with a confidence index.
Visual identification only. Where the VIN or the registration document is legible, read it — this endpoint is for the case where neither is available, or for checking that the car in the photos is the car on the paperwork.

}Authorizations
Organisation API key, sent as Authorization: Bearer chk_live_….
chk_live_…— production inference, live credits,livemode: true,is_staging: false.chk_stg_…— real inference classified as staging, the same live credits,livemode: true,is_staging: true.chk_test_…— identical pipeline against the fixture backend, test credits,livemode: false.
Keys are stored hashed; only the prefix (chk_live_a1b2…) is ever displayed again. A key
may be scoped to a subset of endpoint families — calling outside its scopes is a 403.
Headers
Client-generated key (a UUID is ideal) making this POST safe to retry. The first request
is executed and its response stored for 24 h; any replay with the same key returns that
stored response with Idempotent-Replayed: true and bills nothing. Reusing a key with a
different payload is a 409 idempotency_key_reuse.
8 - 255Steers the fixture backend. Ignored by live keys, 400 test_scenario_not_supported if the
scenario is unknown to the endpoint. Common catalogue:
| Scenario | Effect |
|---|---|
| (absent) | Deterministic success — the endpoint's default fixture. |
empty_result | Success with nothing detected: empty lists, null readings. |
low_confidence | Success with every confidence below 0.5. |
model_error | Job settles failed; the reservation is released. |
slow | Completion after ~30 s — makes wait=true time out. |
insufficient_credits | 402 at admission, no job created. |
Some endpoints add their own scenarios; unsupported common scenarios (for example
empty_result on a generation endpoint) are rejected rather than silently ignored.

Query Parameters
Hold the connection until the job settles and answer 200 with the completed job instead
of 202 with a queued one. Available on fast endpoints only; the ceiling is 30 s, after
which the job keeps running and the call answers 202 as usual.
Body
JPEG, PNG or WebP, 10 MB maximum. Larger files must go through /v1/uploads.
1 <= x <= 100 <= x <= 1ISO 3166-1 alpha-2 market whose model catalogue to prefer — the same shape is badged differently across regions.
"FR"
Response
Job completed synchronously (wait=true).
The unit of work of the API. Every inference call creates one, and every result is read
back from one — synchronously through wait=true, or later through GET /v1/jobs/{id}
or a webhook.
result is populated only in succeeded, error only in failed / expired.
Staging classification. Requires live mode and uses the organisation's shared live credits.
Job identifier — job_ followed by a base58 string.
^job_[1-9A-HJ-NP-Za-km-z]{8,32}$"job_3ZxK9pQr7TnW"
"job"Dotted slug of a CarHub endpoint, the identifier used for jobs and usage.

Every state after processing is terminal.
queued, processing, succeeded, partial, failed, expired, canceled false when the job was created with a chk_test_ key: fixture result, test credits.
Epoch seconds, UTC.
1755300000
When the job left the queue. Null while queued.
1755300000
When the job settled. Null until then.
1755300000
Exact model build that produced the result, as <model>@<release date>. Null until the job starts. Pin your regression tests to it.
"plate-reader@2026-08-27"
Credit accounting for the job. One thousand credits equal one USD. reserved is held at
admission and charged is the real cost after settlement; unused credits are released.
