# Most Accurate Forecast Model share image

`GET /api/og/leaderboard/most-accurate-model`

## Request

- Base URL: `https://www.snowsure.ai`
- URL: `https://www.snowsure.ai/api/og/leaderboard/most-accurate-model`
- Auth: none required

PNG ranking weather models by error against measured snowfall this season.

**Auth:** none.

**Caching:** `Cache-Control: public, max-age=3600, s-maxage=3600, stale-while-revalidate=7200, no-transform`. Matches the leaderboard's hourly refresh. Never `immutable`, so browsers, social scrapers and the CDN fetch a fresh render once the window passes. A changing query parameter (e.g. `&d=2026-09-15`) still forces a fresh render; unknown parameters are ignored.

## Query parameters

- `scope` 'overall' | 'day_1_3' | 'day_4_7' | 'day_8_14'
- `format` 'og' | 'square' | 'story'
- `units` 'metric' | 'imperial'

## Response `200`
