How this service works
Check presence of required issuer/subject or producer/work pins; null is missing, not an invalid credential or artifact for caller-supplied artifact and dataset provenance manifests. No source download, build reproduction, signature verification, proof of origin, causality or scientific validity. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.
Output
Returns a per-row coverage result indicating which required pins (issuer, subject, producer, work) are present or null/missing, without downloading source files, verifying signatures, or assessing scientific validity. Full results are retained for 24 hours; minimal receipt metadata for 90 days.
Example use cases
Artifact provenance audit for a data pipeline
“I have 20 provenance manifest rows for artifacts produced by our data pipeline — can you check whether all of them have the issuer and work pins filled in? Data class is synthetic and all metadata is nonpersonal.”
Dataset submission compliance check
“Before we submit this dataset, can you scan these 15 provenance manifest rows and flag any that are missing the required producer or subject fields? All rows are public, nonpersonal metadata.”
Manifest quality gate before publishing
“Run a required-field coverage check on these 8 provenance manifest rows — I need to know which ones are missing the issuer or subject pins so I can block them from publishing. Data class is public, nonpersonal metadata only.”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/verify/provenance-manifests/required-field-coverage?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, offline check that required provenance metadata pins (issuer, subject, producer, work) are present in manifest rows — without any source download, signature verification, or proof-of-origin logic. Prefer this over heavier provenance pipelines when you only need field-presence coverage for public or synthetic nonpersonal metadata at low cost per call.
Side effects
- Rows array empty or exceeds 32-item limit — validation error
- requiredFields array empty or exceeds 8-item limit — validation error
- nonpersonalMetadata not explicitly set to true — request rejected
- dataClass not one of 'public' or 'synthetic' — enum validation error
- Malformed manifest row structure — fields may be reported as indeterminate
- Result expired after 24-hour retention window — no historical retrieval available
