How this service works
HALOWERK medienwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
A JSON object containing the comparison outcome between the submitted SHA-256 hash snapshot and the previously registered one, including whether the hashes match, any detected delta or change indicator, a confidence band on the result, and metadata about the registered snapshot timestamps.
Example use cases
Media tampering detection for archives
“I need to check whether the video file at this URL has been altered since we registered its hash last month — can you compute its SHA-256, compare it against the stored snapshot, and tell me if there's any difference?”
Compliance audit for published assets
“We published a set of product images two weeks ago and registered their hashes. Can you take the current version of this image, compare its SHA-256 against our stored snapshot, and confirm whether it's been modified?”
Automated content integrity monitoring
“Every day I want you to snapshot the SHA-256 of our main promotional video and compare it to the baseline we registered on launch day — alert me if the hashes ever diverge.”
Technical details
Endpoint
POSThttps://medien.halowerk.com/v1/baumarkt/media/cue-sha256-register/snapshot-compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need hash-level content integrity verification for media assets and want to compare a current SHA-256 snapshot against a previously registered baseline. It is ideal for detecting unauthorized modifications, auditing content drift over time, or enforcing tamper-evidence in media pipelines. Prefer it over full perceptual image comparison (available as a sibling endpoint) when you need cryptographic precision rather than visual similarity scoring.
Side effects
- No prior snapshot found for the given content identifier — returns an error or empty comparison
- Invalid or malformed SHA-256 hash submitted — returns a validation error
- Content identifier not previously registered — comparison cannot be performed
- Network timeout or service unavailability — returns HTTP 5xx
- Payment not processed via x402 — request rejected before processing
