URL to Screenshot API

SnapAPI's entire API is a single endpoint:

GET https://apisnap.dev/api/screenshot?url=https://example.com

Add your API key to the Authorization header, and you get back a PNG image. No SDKs, no webhooks, no multi-step workflows, no WebSocket connections. Just a plain HTTP GET request that returns a binary image.

This works with curl, fetch, requests, HttpClient, or any HTTP client in any programming language.

Required:

• url — Target URL to screenshot (URL-encoded)

Format & Quality:

• format — png (default), jpeg, or pdf
• quality — JPEG quality 1-100 (default: 80)

Viewport:

• width — 320-3840 (default: 1280)
• height — 200-2160 (default: 800)
• deviceScaleFactor — 1-3 (default: 1, use 2 for retina)

Rendering:

• full_page — true/false, capture entire scrollable page
• dark_mode — true/false, emulate dark color scheme
• delay — 0-10000ms, wait after page load
• selector — CSS selector for element-specific capture

Response headers:

• X-Usage-Remaining — Monthly screenshots remaining
• X-Screenshot-Width / X-Screenshot-Height — Rendered dimensions
