The request

One request in. A store-ready set out.

Describe the whole listing in one JSON body: a named preset, set-wide theme tokens, and a slide per screenshot. appscreenshotapi designs, frames, captions, and lints the set, then returns CDN-hosted PNGs in one round trip.

Yes. appscreenshotapi is an API-first store screenshot designer. You POST one JSON request to /v1/renders (a style preset, set-wide theme tokens, and a slide per screenshot) and get back CDN-hosted, store-ready PNGs plus a compliance lint report in the same round trip. It's designed to run from GitHub Actions, Bitrise, Xcode Cloud, or any shell, including an AI coding agent's tool calls.

No. The render engine is deterministic: your real UI screenshots are composited pixel-exact and are never regenerated or "enhanced" by a model, which keeps sets guideline-safe by construction under Apple's 2.3.3 accuracy rule. Same input, same pixels, every time. The only AI surface is the optional POST /v1/briefs assist, which turns a one-sentence brief into an editable design spec that the deterministic engine then renders.

Every response includes a lint array covering headline contrast ratios, thumbnail legibility at store-card size, Google Play's 20% text-area rule, banned phrases like "#1", duplicate caption keywords, and exact Apple/Play dimension validation. Each rule is tagged OFFICIAL (a written store rule) or HEURISTIC (a best-practice check), so humans and agents can decide what to fix before submission.

Canvas presets cover the current App Store Connect classes (iPhone 6.9" at 1290×2796, 1260×2736, or 1320×2868, iPhone 6.5", and iPad 13") plus Google Play phone at 1080×1920 portrait or 1920×1080 landscape. Slides can mix devices too: dual-phone, phone + iPad, real, clay, or flat frames, caption-top or caption-bottom. Locales fan out through output.locales in the same request.

Renders come back as CDN image URLs by default, and the CLI or GitHub Action can arrange them into the locale folder structure deliver expects. Call the API from a lane or workflow step, point deliver at the output folder, and your designed screenshots upload to App Store Connect with no extra glue code.

Small sets render synchronously in one round trip. For big locale matrices, send "async": true to get a 202 with a polling URL, plus an optional webhook_url callback, then fetch GET /v1/renders/{id} when it completes. Requests accept an Idempotency-Key header, so retries in CI are safe.
