# Sky Observations - Export Semantic Parity

> Sky Observations - Export Semantic Parity is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.039327/call, status unknown (last checked 2026-10-20).

Compares parsed typed-record projections of sky observation data for semantic parity, preserving pins and scope while ignoring field order.

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-export-semantic-parity-9f23c85e -d '<json body>'
```

Example prompt: Compare these two sets of sky observation records — up to 20 entries in the before array and 20 in the after array — using public data class, and tell me if they're semantically equivalent, ignoring field order but preserving all pins and scope.

## When to prefer this

Use this endpoint when you need to semantically compare two snapshots or versions of sky observation typed-record projections and want to ignore field ordering while preserving all pin constraints (sky frame, epoch, observer, method). Prefer this over byte-level diff tools when the records are parsed typed projections rather than raw artifact bytes, and when your data is classified as public or synthetic (non-personal).

## Known failure modes

- Array size exceeds maxItems limit of 32, returning validation error
- Invalid dataClass value (must be 'public' or 'synthetic') causes rejection
- nonpersonalMetadata must be exactly true (const), any other value returns error
- Malformed or untyped record entries may cause parse failure
- Network or payment processing failure returns 402 or timeout

## How this service works

Compare parsed typed record projections, preserving all pins and scope while ignoring order; not raw-byte equality or proof of the underlying artifact for sky frame/epoch/observer/method-pinned Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a semantic parity assessment indicating whether the before and after typed-record projections match, preserving all pin and scope constraints (sky frame, epoch, observer, method) while disregarding field order. Does not perform raw-byte equality or certify the underlying artifact.
