Active product: Copart & IAAI Vehicle Auction Data API

## Overview

Apibara.tech provides developers and automotive businesses with structured access to supported Copart and IAAI auction data through one JSON API.

The platform currently indexes 20M+ auction records across current vehicle/lot data and retained historical auction records. This is a record count, not a claim of 20M unique vehicles. More than 2.5M vehicle/lot records are represented in the supported dataset, and approximately 30K+ auction records are added or refreshed daily.

Available data may include vehicle specifications, VINs, lot numbers, auction dates, statuses, current bids, Buy Now prices, final sale prices, damage information, odometer data, title documents, seller details, locations, high-quality source-provided photos, auction history and supported live auction updates.

Apibara.tech is an independent third-party provider. It is not owned by, affiliated with, endorsed by or operated by Copart or IAAI. It is not related to Apibara.com or any blockchain indexing platform.

## API Access

Base URL:
`https://apibara.tech/api/v1/vehicle-auction`

Authentication header:
`X-API-Key: YOUR_API_KEY`

Response format:
`application/json`

Store API keys on a secure backend. Do not expose them in frontend JavaScript, public repositories or browser-accessible configuration.

## Core Endpoints

- `GET /vehicles` — search and filter vehicle auction records
- `GET /vehicles/{slugVin}` — retrieve one vehicle or lot
- `GET /vehicles/{slugVin}/history` — retrieve available auction and sale history
- `GET /vehicles/{slugVin}/related` — retrieve related vehicles
- `GET /vehicles/filters` — retrieve search filter metadata
- `GET /vehicles/{slugVin}/shipping` — retrieve supported shipping information
- `GET /locations` — retrieve supported auction locations
- `GET /shipping/auction-to-port` — calculate supported auction-to-port shipping
- `GET /vehicles/urltodetails` — resolve a supported Copart or IAAI auction URL
- `GET /usage` — retrieve API usage and plan-limit information
- `GET /image-proxy` — retrieve supported auction images through the image proxy

Use the OpenAPI schema and endpoint reference as the source of truth for current parameters, validation rules and response fields.

## Pagination and Plan-Specific Vehicle Search Limits

Vehicle search uses cursor-based pagination.

Current vehicle-search `per_page` limits:

- Test / Basic / Power / Pro — up to 20
- Pro+ / Pro Max — up to 30
- Mega / Mega Max — up to 40

Other endpoints can have different limits. Follow the live OpenAPI schema, authenticated plan and API responses.

## Data Freshness and Synchronization

Apibara.tech automatically collects, normalizes and refreshes supported Copart and IAAI auction records.

Supported live auction fields may update approximately every 10–15 seconds, while general vehicle records may update approximately every 30 minutes. These intervals are approximate and are not guaranteed for every vehicle.

The `updated_at` field represents when normalized lot data actually changed; it is not intended to be re-stamped merely because a scheduled refresh found no changes. This supports incremental synchronization workflows using cursors, checkpoints and idempotent upserts.

## Historical Data

Available auction and sale history can be retrieved through:

`GET /vehicles/{slugVin}/history`

History coverage varies by VIN, source, date and retained record availability. An empty history response does not prove that a vehicle has never appeared at auction.

Auction history is not a complete ownership, accident, registration or government title history.

## Integration Support

Apibara.tech provides integration assistance for Vehicle Auction Data API projects, including API-key setup, endpoint selection, synchronization patterns, WordPress integrations and custom API implementation support.
