# Get Validation Summary

`GET /api/validation/summary`

## Request

- Base URL: `https://epw.tools`
- URL: `https://epw.tools/api/validation/summary`
- Auth: none declared

Return MAE/RMSE/bias of EPW.tools design conditions vs published ASHRAE.

Reads the JSON written by `backend/generate_validation_report.py`. If the
file is missing we attempt to regenerate it on the fly from the per-edition
CSVs so the first request after a fresh deploy still works.

## Response `200`

Successful Response

- unknown
