# Direct image (no auth needed for free tier)
curl "https://snap.i2dev.com/v1/screenshot?url=https%3A%2F%2Fgithub.com" > github.webp
# JSON API (with API key)
curl -X POST https://snap.i2dev.com/v1/screenshots \
-H "Authorization: Bearer YOUR_KEY" \
-d '{"url": "https://example.com"}'Embed directly in HTML — no JavaScript required:
<!-- Display only -->
<img src="https://snap.i2dev.com/v1/screenshot?url=https%3A%2F%2Fexample.com&width=1280" />
<!-- CORS mode: JavaScript/canvas can read the pixels -->
<img crossorigin="anonymous" src="https://snap.i2dev.com/v1/screenshot?url=https%3A%2F%2Fexample.com&width=1280" />The CORS-enabled form is public and sends no credentials. Use it when your page needs canvas or JavaScript pixel access.

Frequently asked questions
Do I need an account to use the screenshot API?
No. The anonymous GET /v1/screenshot endpoint works with no signup and no API key — up to 30 screenshots a day per IP.
What's the daily limit, exactly?
30 screenshots per day per IP, resetting at midnight UTC. Each network also shares a much higher 10,000-attempt daily ceiling, which exists to stop rotating cloud or proxy egress from bypassing the per-IP limit — it's not meant to constrain a single visitor. Cache hits never count against either daily quota. A repeat request for the exact same canonical options is usually served from the CDN edge and doesn't touch the per-minute rate limit at all; the rate limit only applies to requests that reach the origin, including any cache hit served from storage rather than the edge.
What happens when I hit a limit?
Rate-limit and quota responses return HTTP 429 with a Retry-After header and a scope header identifying which limit was hit. Other capture failures return HTTP 200 with a placeholder image, so existing <img> embeds keep rendering instead of breaking.
What image formats and sizes are supported?
WebP (default), JPEG, or PNG, at widths from 1–1920px and heights from 1–1080px, plus an optional full-page capture mode that captures the whole scrollable page.
Can I use the screenshot directly in an <img> tag?
Yes — the default response sends no credentials, so it works in a plain <img src="...">. Add crossorigin="anonymous" if your page needs canvas or JavaScript pixel access to the image.
Testing UIs, not just capturing them?
Snap's Hosted Visual CI adds centralized baselines, PR diffs, and a review dashboard on top of this same engine. Comparing hosted visual regression tools? See the Percy vs Chromatic vs Argos pricing comparison.
