Search & Discovery

Search tools go beyond basic page content. Use semantic embeddings for similarity search across cached content, discover API endpoints from network traffic patterns, and resolve domains via DNS-over-HTTPS. These tools help your agent build understanding across browsing sessions.

Tools

Tool	Description	Key Parameters
`embedding_search`	Semantic similarity search across cached content	`text` (required), `top_k`
`embedding_upsert`	Store a text embedding for semantic search	`source_id` (required), `content` (required)
`network_discover`	Discover API endpoints from captured network traffic	(none)
`dns_resolve`	Resolve a domain to IP addresses via DNS-over-HTTPS	`domain` (required)
`page_diff`	Compare current page to cached version	`url`

Examples

Semantic search across browsing history

{
  "tool": "embedding_search",
  "arguments": {
    "text": "companies hiring Rust engineers remotely",
    "top_k": 10
  }
}

Finds cached content that is semantically similar to the query, even if the exact words do not match. Store custom embeddings with embedding_upsert to build a searchable knowledge base.

Discover API endpoints

{
  "tool": "network_discover",
  "arguments": {}
}

Analyzes captured network traffic patterns from browsing and returns detected API endpoints: URL templates, HTTP methods, auth types, and request/response schemas. Useful for understanding how a site's frontend communicates with its backend.

Detect page changes

{
  "tool": "page_diff",
  "arguments": {
    "url": "https://example.com/jobs"
  }
}

Compares the live page content against the cached version to show what has changed. Useful for monitoring job listings, price changes, or any content that updates over time.
