Screenshot Sizes JSON API

The endpoint

curl https://snapmonk.com/tools/screenshot-sizes.json

Returns both stores with per-device specs: pixel dimensions, aspect ratio, whether the slot is required, file rules, upload count rules, and extras like the Google Play feature graphic. Responses are cached for a day and carry a lastReviewed date (currently 2026-07-03) so you can see data freshness.

Use it in a script or CI check

A common use: validate your exported screenshots against current store requirements before upload, so a spec change fails your build instead of your App Store submission.

const res = await fetch('https://snapmonk.com/tools/screenshot-sizes.json')
const { stores, lastReviewed } = await res.json()

const appStore = stores.find((s) => s.id === 'app-store')
for (const spec of appStore.specs) {
  console.log(spec.device, `${spec.width}x${spec.height}`, spec.required ? 'required' : 'optional')
}

Stability promise

• The URL never moves.
• The response shape only ever gains fields. Existing fields are never renamed, removed, or retyped.
• CORS stays open (Access-Control-Allow-Origin: *).
• Free with attribution: link to snapmonk.com wherever you use the data.
