How it works
The web, in the format agents were made for.
Mark crawls the web, strips away everything an agent doesn't need — navigation, ads, JavaScript, layout — and serves the content as clean, structured markdown through a simple REST API.
- Structured markdown with frontmatter metadata
- Vector-indexed for semantic search
- Fresh by contract — content is kept current
- License-aware — we respect robots.txt and content rights
// GET /r/{domain}
{
"title": "What's New in Rails 8.1",
"source": "railsblog.com",
"words": 2847,
"fresh": "2026-08-19T10:30:00Z",
"markdown": "# What's New in Rails 8.1\n\n..."
}
For agents
Clean input, reliable output.
When your agent reads from Mark, it gets exactly what it needs: the content, structured and clean. No parsing HTML tables, no guessing which div contains the article, no wasted tokens on cookie banners and sidebar widgets.
- 90% fewer tokens vs. raw HTML scraping
- Consistent structure across millions of sites
- Built-in vector search for semantic queries
- Sub-millisecond API response times
// Before Mark: scraping raw HTML
tokens: 47,200
signal: 12% (actual content)
// After Mark: clean markdown
tokens: 4,200
signal: 98% (all content)
// Same page. 90% less waste.
For builders
Simple API, powerful primitives.
One endpoint. One format. Build agents that read the web without worrying about the mess underneath. Mark handles the crawling, parsing, indexing, and freshness — you just call the API.
- RESTful API with JSON responses
- Search by URL, topic, or semantic query
- Batch processing for large-scale ingestion
- Webhook notifications for content updates
// Search for content
GET /v1/search?q=ruby+rails+performance

1. "Rails 8.1 Performance Guide" (score: 0.94)
2. "Optimizing ActiveRecord" (score: 0.91)
3. "Turbo Streams Deep Dive" (score: 0.88)
