How this service works
Track changes in public JSON, CSV, XML or text datasets with deterministic normalization and hashes.
Output
Returns a structured change report including a deterministic hash of the current dataset, normalized before/after evidence of any changed fields or records, a diff summary highlighting additions/removals/modifications, and a timestamp of when the check was performed.
Example use cases
Government data change alert
“Monitor this public CSV at https://opendata.cityofchicago.org/permits.csv and tell me if any rows have been added or removed compared to yesterday's snapshot — include the before/after diff and a hash.”
Financial data integrity check
“Has this public JSON feed at https://api.fiscaldata.treasury.gov/services/api/v1/debt changed at all? Run a normalized comparison and give me the cryptographic hash of the current state so I can verify integrity.”
Open data pipeline freshness check
“I need to know if this XML dataset at https://registry.data.gov/harvest/source.xml has been updated — compare it to my previous baseline and show me exactly what records changed with normalized before/after evidence.”

POSThttps://9dmb38pvlp8dr1d3rtfjpe934o.ingress.h4i-dedicated.eu-sw-2.digitalfrontier.so/api/seller/v4/public-data/dataset-changeWhen to prefer
Choose this endpoint when you need structured, deterministic change detection on public JSON, CSV, XML, or text datasets — especially when you need cryptographic hashes for integrity verification or normalized diffs for reliable comparison across schema variations. Prefer it over generic web-page change detectors when the source is structured data rather than HTML prose.
Side effects
- URL not publicly accessible — returns error indicating unreachable source
- Unsupported data format — returns error if content type cannot be parsed
- Dataset too large — may return timeout or size-limit error
- Network or upstream source error — returns fetch failure with status details
- Malformed data — normalization may fail if source is corrupt or inconsistent
