How this service works
Compare Separate provider confidence bands from unknown confidence values. against a bounded caller-supplied previous snapshot and return exact change witnesses. Baseline is caller supplied and is never authenticated as historical server output. Pure bounded timing/source-quote validation runs before payment. Exactly one current motor call, zero baseline provider calls. Full current provider disclosure retained; baseline is not submitted to the provider.
Output
A JSON object listing exact change witnesses between the caller-supplied baseline confidence histogram snapshot and the current live provider output, including which confidence bands appeared, disappeared, or shifted, along with source attribution and timing validation metadata. The current provider disclosure is fully retained; the baseline is not submitted to the provider.
Example use cases
Detecting confidence drift in media source
“I have a confidence histogram snapshot I saved last week from the baumarkt media provider — can you compare it against the current output and show me precisely which confidence bands shifted or appeared/disappeared?”
Auditing provider reliability over time
“Run a snapshot compare on the confidence histogram for baumarkt media using this baseline I supplied, and give me the exact change witnesses so I can audit whether the provider's confidence scores have drifted since my last check.”
Monitoring confidence band stability before payment
“Before I approve payment, compare the current confidence histogram against my stored baseline snapshot and confirm whether the source confidence distribution is stable or has changed — I need the exact diff witnesses.”

Endpoint
POSThttps://medien.halowerk.com/v1/baumarkt/media/confidence-histogram/snapshot-compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect precise changes in confidence histogram distributions between a caller-supplied historical baseline and the current live provider output, especially when you want full current provider disclosure without re-authenticating or re-submitting the baseline to the provider. It is ideal for auditing confidence drift, monitoring stability before triggering payment flows, or generating evidence of change for compliance purposes.
Side effects
- Malformed or missing baseline snapshot in request body returns a 400 error
- Baseline snapshot format does not match current provider histogram structure, yielding a schema mismatch error
- Timing bounds exceeded, causing validation to fail before the provider call is made
- Current provider call fails or times out, returning a provider error with no diff output
- Confidence band keys in the baseline are unrecognized, resulting in an empty or partial change witness list
