Returns the registered owner(s) (name and identification number), the vehicle characteristics (brand, line, model year, class, body, color, VIN, engine/chassis/serial numbers), the traffic-license and import records, SOAT and técnico-mecánica (RTM) history, any accident on record, recent and pending procedures (trámites), and guarantee/lien and ownership-limitation summaries. `found: false` when the plate has no record. Supports async delivery: set `Prefer: wait=N` for an inline result, pass `callback_url` to receive a POST when ready, or poll `GET /jobs/{id}`. ## OpenAPI ````yaml /api-reference/openapi.json post /co/runt/vehicle-history-by-plate/v1 openapi: 3.1.0 info: title: Croma Marketplace API version: 1.0.0 description: >- Government-data APIs for Colombia, Peru, Mexico, United States, Brazil, El Salvador, Bolivia, and Japan, plus global web search. Croma normalizes public-sector data into structured JSON for product teams and AI agents. Every operation is a POST with a JSON body and an organization API key as a bearer token; every operation is an idempotent lookup and accepts an optional `Idempotency-Key` header. Paths carry their major version (`/v1`); the versioning and deprecation policy, including the `Deprecation` and `Sunset` headers a retiring endpoint sends, is at https://docs.usecroma.com/versioning. Rate limits are per organization and reported on every response (`RateLimit-Policy`, `X-RateLimit-*`): https://docs.usecroma.com/rate-limits. termsOfService: https://usecroma.com/en/terms contact: name: Croma support url: https://usecroma.com/en/support email: support@usecroma.com servers: - url: https://api.croma.run security: [] paths: /co/runt/vehicle-history-by-plate/v1: post: tags: - Colombia - RUNT summary: RUNT Vehicle History by Plate description: >- Look up a Colombian vehicle's history in RUNT (Registro Único Nacional de Tránsito) by plate alone, without the owner's document.

Every Croma operation is an idempotent lookup: repeating a request with the same body returns the same result and creates nothing, so retrying after a timeout or network failure is always safe. The key is echoed back in the `Idempotency-Key` response header so you can correlate a retry with its first attempt. Each attempt that reaches the API counts against the rate limit. schema: type: string maxLength: 255 example: 0f8e9a42-6b7c-4d1e-9a3f-2c5d7e8f9a0b Prefer: name: Prefer in: header required: false description: >- Set `wait=N` to hold the connection up to N seconds for an inline result.
