Agent Souk – Web Page Change Detector

Choose this endpoint when you need a deterministic, reproducible diff of a webpage or HTTP response over time without any LLM interpretation — ideal for price monitoring, changelog tracking, API response drift detection, or any workflow where exact text changes matter and hallucination risk must be zero. Prefer it over LLM-based summarization tools when you need to know precisely what bytes changed, not a paraphrase of the change.

• URL is not publicly accessible or returns a non-200 status — endpoint cannot fetch the page
• URL exceeds 2048 characters — request rejected
• URL points to a page requiring authentication — fetch fails silently or returns a login page diff
• First call for a URL establishes the baseline and returns no diff — subsequent calls show changes
• Glob patterns in ignore array are malformed — may not suppress intended lines
• reset:true wipes the stored snapshot, so the next call returns no diff and starts a new baseline
