Response schema

#/definitions/carmax.VehicleResponse

Overview

Returns a normalized CarMax vehicle listing: full vehicle spec (make, model, trim, mileage, colors, engine, transmission, fuel economy, pricing), equipment features, labeled specifications, warranty coverage, accident/owner history, and CarMax's return guarantee terms. Credential-free public data sourced primarily from CarMax's own mobile-app API, backfilled with the website's server-rendered page for accident/owner history and warranty terms the mobile API doesn't expose. Developers commonly use this endpoint for data enrichment, monitoring, research dashboards, internal automation, and agent-native workflows that need repeatable structured public web data. Authentication uses the documented Crawlora headers, and usage is metered with the credit cost shown on this page.

Infrastructure behavior

This endpoint is executed through Crawlora's managed scraping infrastructure.

• Proxy strategy: managed automatically where needed
• Browser rendering: enabled for supported targets that require rendered HTML or JavaScript execution
• Browser cluster: supported dynamic workloads can be routed through distributed browser instances
• Retry behavior: automatic retry/fallback may be used depending on endpoint type
• Challenge handling: challenged pages or unusable upstream HTML are detected and surfaced clearly when they cannot be used
• Billing: credits are charged only for successful 2xx responses
• Observability: responses include request context where available

Browser cluster behavior

Some targets require real browser execution because the data is loaded through JavaScript, dynamic rendering, or interaction-like browser behavior.

For supported endpoints, Crawlora can route requests through a managed browser cluster. This allows Crawlora to execute JavaScript, load dynamic content, apply browser-level request behavior, and normalize the rendered result into JSON.

You do not need to operate your own Playwright, Puppeteer, Chrome, proxy, queue, or retry infrastructure.

Response behavior

- `stock_number` must be numeric; a non-numeric value returns `400` before any upstream request is made. - A stock number that is well-formed but no longer exists (sold, removed, or never existed) returns `404`. - **Hybrid sourcing**: most fields come from CarMax's mobile-app API. Three things it doesn't expose are backfilled from the website's own page instead — `history` (accident/owner counts), `warranties` (structured coverage terms), and `body`/`fuel.type`. If that backfill fetch fails for any reason, the response is still returned successfully with everything the mobile API provided; `history` is **omitted entirely** in that case (not present as `null` or a zero-valued object) rather than showing a misleading `accident_count: 0`/`owner_count: 0` that would read as "verified clean" when it's actually "unknown". `warranties` similarly comes back as an empty list, and `body`/`fuel.type` as empty strings, in that scenario. - `vehicle_guarantee` (CarMax's return-policy terms) and exact `horsepower`/`cylinders`/`engine_torque_lb_ft` figures are only available via the mobile API and have no website-scrape equivalent to fall back to. - `specs` entries from the mobile API don't carry a `category` (CarMax's mobile response is a flat name/value list, unlike the website's categorized spec groups) — `category` is empty in that case.

Error behavior

Crawlora does not silently return bad data when the upstream page cannot be used.

When possible, Crawlora returns structured error context so your integration can retry, back off, or inspect the request.
