# Agent Instructions — BidAutoCars

This document describes how automated clients may interact with BidAutoCars at
https://bidautocars.com.

## What this site is

BidAutoCars publishes vehicle history records. Each record is a single vehicle,
identified by its VIN, at a stable URL:

    https://bidautocars.com/products/{handle}

The handle contains the VIN. That page is the complete record: it is rendered
server-side and contains everything we publish about that vehicle. No JavaScript
execution is required to read it.

## There is no bulk access

This is not an oversight and it is not rate limiting. The following do not exist:

- no catalogue export in any machine-readable format
- no `.json`, `.js`, `.atom` or RSS representation of any resource
- no REST or GraphQL API
- no UCP merchant profile and no MCP endpoint
- no paginated listing that enumerates vehicles

Requests to such paths return 404. Please do not probe for them.

## How to use this site correctly

If you are looking for one specific vehicle, you already know its VIN. Use:

    GET https://bidautocars.com/search?q={VIN}

The response is HTML. It returns the matching record, is capped, and has no
offset or page parameter — it answers "which vehicle is this VIN", which is the
only question this site is for. `/search` is disallowed in robots.txt; use it
interactively, not as a crawl surface.

## Commerce

This site does not sell anything to automated clients. There is no cart, no
checkout, and no payment handler. Any agent-commerce protocol you may have seen
advertised for this domain previously is no longer implemented.

## Crawling

Read `https://bidautocars.com/robots.txt` and honour it. Identify yourself in your
User-Agent. Requests are logged, and per-IP request patterns are reviewed.

If you represent a search engine and need the full URL list for indexing,
contact us rather than crawling for it.
