- Paginated bid history for supported live and completed auctions.

- MCP access for ChatGPT, Claude, Cursor, Claude Code, Windsurf, and other compatible clients.
Who this is for
This page is for developers and operators who want a structured data feed rather than another browsing destination. Old Cars Data is designed for products that need to answer questions like what a car sold for, what comparable sales look like, whether a live auction is under market, and which trims or years are moving.
Common integration paths
| Workflow | Recommended surface | Why |
|---|---|---|
| Backend pricing engine | REST API | Predictable JSON, pagination, filters, and server-side auth |
| AI assistant or agent | MCP | Tool calls let the model query current collector-car data directly |
| Internal research dashboard | REST API | Good fit for filtering, sorting, and storing normalized records |
| Appraisal workflow | REST API or MCP | Comparable sales and market stats can support human review |
