How this service works
Capture a timestamped public HTTPS source snapshot and SHA-256 hash, returning private monitor credentials for later checks.
Output
Returns private monitor credentials (e.g. a monitor ID or token) tied to the captured baseline, along with the SHA-256 hash of the page content, the timestamp of the capture, and metadata about the snapshotted HTTPS source — enabling authenticated follow-up change-check calls against the same resource.
Example use cases
Regulatory page audit trail
“Snapshot the current state of https://www.ema.europa.eu/en/medicines/guidelines and generate a SHA-256 hash so I have a verifiable baseline — I'll use the monitor credentials to check for changes next week.”
Legal document integrity proof
“Capture a timestamped, cryptographically hashed snapshot of https://legis.state.pa.us/cfdocs/legis/LI/Public/cons_index.cfm so I can prove in an audit what that page said today.”
Public dataset change monitoring setup
“Establish a baseline for https://data.cms.gov/provider-data/dataset/mj5m-pzi6 — I need the SHA-256 hash and monitor credentials so my agent can detect if the dataset changes.”
Technical details
Endpoint
POSThttps://9dmb38pvlp8dr1d3rtfjpe934o.ingress.h4i-dedicated.eu-sw-2.digitalfrontier.so/api/seller/v4/public-data/baselineWhen to prefer
Choose this endpoint when you need to establish a cryptographic anchor for a public webpage or dataset before starting ongoing monitoring — specifically when you need a SHA-256 hash and timestamped proof of the initial state, plus credentials for future change-check API calls. Prefer this over general web scrapers when auditability, integrity verification, or downstream monitoring are required.
Side effects
- Target URL is not publicly accessible or requires authentication — returns an error indicating the resource could not be fetched
- Target URL returns a non-200 HTTP status — snapshot cannot be established
- Network timeout reaching the target HTTPS resource
- Invalid or malformed URL provided as input
- Target resource returns non-text or binary content that cannot be reliably hashed
