x402
Ephemeris Snapshots - Export Semantic Parity is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.039329/call, status unknown (last checked 2026-10-20).
Compares two sets of fixed-epoch celestial position export declarations by exact integer-metre scaling, verifying coordinate frame consistency without performing live ephemeris queries or predictions.

How this service works
Compare supplied fixed-epoch position exports by exact integer metre scaling, preserving declared coordinate frames. No ephemeris query, frame rotation or celestial prediction. Offline typed metadata only. Retained-result recovery: 24 hours; minimal receipt metadata: 90 days.
Output
Returns a structured parity report indicating whether the before and after ephemeris snapshot arrays match on integer-metre scaling and declared coordinate frames, without performing live ephemeris queries or frame rotations. Results are retained for 24 hours; receipt metadata is retained for 90 days.
Example use cases
Pre/post pipeline export parity check
“I have two batches of fixed-epoch celestial position exports from before and after a pipeline update — can you compare them for exact integer-metre scaling parity and flag any coordinate frame mismatches? Use public data class.”
Coordinate frame integrity audit
“Run a semantic parity check on these before and after ephemeris snapshot arrays to confirm the declared coordinate frames are preserved and the metre scaling is consistent across both sets.”
Release validation for snapshot exports
“Before we ship this celestial data release, compare the old and new position export snapshots — both marked as synthetic — to verify the integer-metre scaling matches and no coordinate frame drift occurred.”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/celestial/ephemeris-snapshots/export-semantic-parity?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that two fixed-epoch celestial position export snapshots are semantically equivalent in terms of integer-metre scaling and coordinate frame declarations, without needing live ephemeris data, frame rotation, or celestial prediction. Prefer it over live ephemeris query endpoints when your data is already exported and you only need offline structural and scaling consistency validation.
Side effects
- Mismatched array lengths between before and after inputs may produce indeterminate comparison results
- Arrays exceeding 32 items will be rejected by schema validation
- Non-integer metre values in position data may cause parity check failures
- Invalid or unsupported coordinate frame declarations will trigger validation errors
- nonpersonalMetadata must be exactly true or the request will be rejected
- Missing required dataClass enum value ('public' or 'synthetic') causes request rejection
