# Sky Observations Schema Directionality Analyzer

> Sky Observations Schema Directionality Analyzer is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035235/call, status unknown (last checked 2026-10-16).

Analyzes the directional schema alignment of closed sky observation export fields, comparing before/after record sets for supplied public or synthetic data.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sky-observations-schema-directionality-analyzer-558ae218 -d '<json body>'
```

Example prompt: Compare my before and after sky observation record arrays — the before set has 5 entries and the after set has 3 — using public data class with nonpersonal metadata only, and tell me whether the export fields are directionally consistent.

## When to prefer this

Choose this endpoint when you need to deterministically compare before-and-after sets of sky observation export records for schema directionality — particularly useful for validating that closed export fields remain consistently oriented across dataset versions, for public or synthetic celestial data only, where nonpersonal metadata compliance is required.

## Known failure modes

- before array is empty or missing (minItems:1 required)
- before or after arrays exceed 32 items (maxItems:32)
- dataClass value not one of 'public' or 'synthetic'
- nonpersonalMetadata not set to true (const:true required)
- malformed record structures in before/after arrays causing parse errors
- service unavailable or payment not processed correctly

## How this service works

Compare closed export-field Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a schema directionality analysis comparing before and after sky observation record arrays, indicating whether closed export fields are aligned, any directional mismatches detected, and a summary of the field-level comparison for the specified data class.
