How this service works
Compare a company page's live content against a saved snapshot.
Output
Returns an array of added text lines, an array of removed text lines, and a natural-language change_summary describing what shifted between the snapshot and the live page.
Example use cases
Competitor pricing page monitoring
“Has anything changed on Stripe's pricing page at https://stripe.com/pricing since it was last snapshotted? Show me what was added or removed and give me a quick summary.”
Tracking competitor team changes
“Check the team page at https://linearapp.com/about for any changes — I want to know if they've added or removed any team members since the last snapshot.”
Monitoring SaaS feature announcements
“Run a change check on https://notion.so/product — did they add or remove any features or product messaging since the snapshot was taken?”
Technical details
Endpoint
POSThttps://agents.bytemine.ai/functions/v1/api-gateway/company/intel/changes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect what specifically changed on a known company webpage between two points in time, particularly for competitive intelligence tasks like pricing shifts, product updates, team changes, or messaging pivots. Prefer this over a full page analysis when you already have a snapshot baseline and want a diff rather than a full extraction.
Side effects
- No snapshot exists for the given URL yet — the system may return an empty diff or an error indicating no baseline
- URL is inaccessible or returns a non-200 response — the comparison cannot be completed
- Page content is JavaScript-rendered and may not be fully captured — diff may be incomplete
- No meaningful changes detected — added and removed arrays return empty with a summary stating no changes
- Malformed or invalid URL input — returns a validation error
