Features

The complete webpage intelligence stack

Every tool you need to see, understand, and monitor any website — from one API.

🔍

Page Intelligence

Structured understanding of any page — page type, primary CTA, nav, forms, technologies, word count, and load time. DOM-based, no AI cost.

📸

Visual Snapshots

Pixel-perfect captures in under 2 seconds. PNG, JPEG, WebP. 30-minute intelligent cache. Full-page, dark mode, custom viewport.

🔔

Structural Monitors

Scheduled captures with visual diff AND structural diff. Detect CTA changes, page type shifts, and technology swaps — not just pixels.

🧠

Metadata Extraction

Title, OG tags, favicon, canonical, headings, and links — standalone or bundled into the analyze call. No extra browser session.

📄

PDF Generation

Convert any URL to a PDF in one call. A4, Letter, Legal, landscape, custom margins, background colors. No headless browser to manage.

🖼

HTML → Image

POST raw HTML, get back a pixel-perfect PNG. Generate OG cards, email previews, and dashboard exports on the fly.

🛡

Clean Captures

Built-in ad blocker, cookie consent dismissal, and 9 device presets — iPhone, Pixel, iPad, desktop. One parameter, clean results.

Use cases

Built for automation, built for intelligence

Every workflow that needs to see, understand, or monitor a webpage.

AI Agents

Give your agent eyes and understanding. One call returns what the page is, what it wants the user to do, and a snapshot — structured, not raw HTML.

Competitive Intelligence

Monitor competitor pricing pages, CTAs, and tech stacks. Get a webhook the moment something structural changes.

SEO & Content Audits

Extract H1s, word counts, page types, and OG metadata at scale. No browser setup, no parsing.

Visual Regression Testing

Capture snapshots before and after every deploy. Pixel diff + structural diff in CI/CD.

Link Previews

Rich previews for chat apps, CMSs, and social platforms. OG image, title, description — one call.

Automation Workflows

Plug into n8n, Zapier, Make, or any HTTP workflow. Zero dependencies, works from any stack.

Built for every stack

Applications don't just need to access webpages anymore — they need to understand them.
SnapAPI is the infrastructure layer that makes that possible.

AI agent pipelines Monitoring tools SEO platforms Automation workflows Competitive intelligence Link preview services Visual regression testing Content auditing

Works with curl, Node.js, Python, Go, or any HTTP client. No SDK required.
