How It Works

1

Agent requests a URL

Any AI agent sends a GET request with the target URL. If the page is cached and fresh, the SOM representation is returned instantly.

2

Cache miss triggers a crawl

On a miss, the cache fetches the page via a headless browser, converts it to SOM using Plasmate, and stores the result with a category-based TTL.

3

All agents benefit

Subsequent requests for the same URL are served from cache. No redundant crawls, no wasted tokens, no duplicate browser sessions.
