# DragGap agent guide

DragGap is a public, read-only vehicle catalogue and interactive acceleration comparison site. It does not require authentication or accept payments.

## Recommended entry points

- Human and browser-agent interface: https://draggap.com/
- Comparison question index: https://draggap.com/comparisons/
- Full machine-readable content briefing: https://draggap.com/llms-full.txt
- Public OpenAPI description: https://draggap.com/openapi.json
- Data provenance manifest: https://draggap.com/data/vehicles/manifest.json
- Vehicle catalogue: https://draggap.com/data/vehicles/catalog.json

## Browser interaction

Open **Change Cars**, search or choose one vehicle in each lane, load the matchup, then select **Start Race**. The live 1/4-mile and 1 km timing, trap speed, acceleration and physical gap all come from the same 120 Hz deterministic simulation.

## Accuracy and citation rules

- Describe race and acceleration results as simulated engineering estimates, never as instrumented measurements.
- Attribute EPA configuration and economy fields to FuelEconomy.gov.
- Attribute make/model identity confirmation to NHTSA vPIC.
- Attribute supplemental power, torque, mass and generation data to the ODbL Open Vehicle Specs source.
- Preserve the distinction between official, supplemental and modelled fields.

DragGap does not currently expose an A2A or MCP server. Do not infer one from the OpenAPI document.
