How this service works
Change watch for extract download links as json: runs the check, compares it with the result from your previous call for the same url (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.
Output
Returns the current set of download links as JSON, a boolean 'changed' flag indicating whether they differ from the previous call, a diff object listing which fields changed with before/after values, and the timestamp of when the page was last seen. Results are compared against a snapshot stored for up to 90 days.
Example use cases
Track software release download links
“Watch the downloads page at https://myapp.io/releases and alert me whenever new download links appear or existing ones change — I want to know the moment a new version is published.”
Monitor open-data portal for new datasets
“Check https://data.gov/datasets/export and tell me if any of the download links have changed since the last time you looked, including which links were added or removed.”
Detect firmware file updates on manufacturer page
“Keep monitoring https://router-brand.com/support/firmware-downloads and tell me true or false whether the download links changed, and if so, show me exactly what was before versus what's there now.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/watch/page/download-links/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect changes to download links on a specific web page over time rather than just extracting them once. It is ideal for scheduled monitoring workflows where you want diff-aware alerting (added/removed/changed links) without building your own comparison logic. Prefer it over a plain extraction endpoint when the 'has anything changed?' question is more important than the raw current state.
Side effects
- Target URL is unreachable or returns a non-200 status — check will fail or return no links
- No previous snapshot exists (first call) — 'changed' will be null or false with no diff
- Page has download links behind authentication or JavaScript rendering — may not be extracted
- Snapshot has expired (older than 90 days) — no before/after comparison available, treated as first call
- Rate limit or payment failure (x402) — request rejected before check runs
