The demo turns these fields into a short answer, keeping screens and charging separate. Each screen option includes its check result and cable plan. Each charging result names the required power supply. Your site can display the same facts in its own wording.
Search by model or manufacturer part number. This works for computers, docks, monitors, chargers, cables and adapters.

To start from an accessory, filter the downloaded matches by dock_id or accessory_id and use the corresponding host_id values. Keep the status, screen setup and requirements with each match. The API’s ready-made lists currently start from a computer; there is no separate accessory-to-computers endpoint.
You can inspect the sample in a spreadsheet. Using the data automatically on your website requires a developer or a compatible import tool.
Full downloads currently use JSON. The CSV contains selected examples. Update frequency and delivery terms for the paid service are still being finalized.
Each answer checks screens, charging and connections separately. Check all three before recommending a complete setup.
The data comes from manufacturer documentation. We have not physically tested every combination. Check optional ports, included accessories and any requirements in the answer.
