How this service works
Count joint missing owner, input and output schema pins in HTTP contract metadata. An incomplete declaration does not establish an unavailable or unsafe runtime service. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.
Output
Returns counts and patterns of jointly missing metadata fields (owner, input schema pin, output schema pin) across the submitted HTTP contract records, indicating how frequently these absences co-occur. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days.
Example use cases
API governance audit for contract completeness
“I have 25 HTTP contract metadata entries from our internal API registry, all public and nonpersonal. Can you count how many of them are simultaneously missing the owner, input schema, and output schema pins so I can see where the worst co-occurring gaps are?”
Pre-publication schema gap detection
“Before we publish this batch of 15 synthetic API contract definitions, can you run a co-occurrence check to find any that are missing both owner info and schema declarations at the same time?”
API metadata quality scoring pipeline
“We're building a quality report for our API catalogue. Can you analyze these 32 public, nonpersonal HTTP contract records and report which missingness patterns — like missing owner plus missing output schema — occur together most often?”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/verify/api-contracts/missingness-cooccurrence?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quantify co-occurring declaration gaps — specifically joint absences of owner, input schema, and output schema pins — across a batch of HTTP contract metadata records. It is distinct from single-field required-field checks (use the Required-field coverage sibling for that) and is best suited for governance audits, data quality pipelines, and pre-publication reviews where pattern-level missingness analysis across multiple contracts matters. Supports only public or synthetic, nonpersonal metadata.
Side effects
- Batch exceeds 32 contracts — request rejected with validation error
- nonpersonalMetadata is not set to true — request rejected
- dataClass not set to 'public' or 'synthetic' — invalid enum error
- Empty contracts array (minItems:1 not met) — validation failure
- Malformed contract objects in array — parsing error returned
