How this service works
Compare closed source-pack ingestion fields and accepted media labels for request narrowing. No parser execution, schema resolution or guarantee for undeclared constraints. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.
Output
Returns a comparison of closed source-pack ingestion fields and accepted media labels between before and after states, indicating directionality and narrowing constraints. No parsed schema resolution or guarantees for undeclared constraints are provided. Results are retained for 24 hours; minimal receipt metadata is kept for 90 days.
Example use cases
Media label compatibility check
“I need to check whether the media labels 'application/json' and 'text/plain' are accepted in the after position for a source pack using public data — can you compare that against my before labels of 'text/csv'?”
Field coverage audit before ingestion
“Before I submit a source pack ingestion request, can you compare these 15 before-fields and 10 after-fields to see how the schema directionality lines up, using synthetic data class?”
Request narrowing constraint review
“I want to narrow a source pack request — can you look at my before field list (5 entries) and after field list (3 entries) with nonpersonal metadata only and tell me what the directionality comparison says about accepted constraints?”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/context/source-packs/schema-directionality?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, offline typed comparison of source-pack schema directionality — specifically to check ingestion field overlap and accepted media labels between before and after states — without triggering parser execution or schema resolution. Ideal for pre-flight narrowing audits on nonpersonal, public or synthetic data.
Side effects
- Missing required 'before' array (minItems:1) returns validation error
- afterMedia or beforeMedia arrays exceeding 3 items rejected
- nonpersonalMetadata not set to true (const) causes rejection
- dataClass value outside 'public' or 'synthetic' enum returns error
- Undeclared constraints not covered — endpoint makes no guarantee for out-of-spec fields
- After array exceeding 32 items rejected
