# Ecology Observations – Export Semantic Parity

> Ecology Observations – Export Semantic Parity is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.039315/call, status unknown (last checked 2026-10-25).

Compares two sets of parsed ecology observation record projections for semantic parity, preserving field pins and scope while ignoring record 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 ecology-observations-export-semantic-parity-ff29299f -d '<json body>'
```

Example prompt: Compare these two sets of ecology observation records — the 'before' batch and the 'after' batch — and tell me if they're semantically equivalent, treating them as public data and ignoring record order but preserving all field and scope pins.

## When to prefer this

Use this endpoint when you need to confirm semantic equivalence of ecology observation record projections after a transformation, migration, or export step — particularly when record order may differ but field-level pin and scope fidelity must be guaranteed. Prefer this over raw byte-comparison tools when order is irrelevant but structural correctness is critical, and over general diff tools when ecology-specific field pinning semantics are required.

## Known failure modes

- Exceeds maximum 32 items in before or after array — request rejected
- Invalid dataClass value (not 'public' or 'synthetic') — validation error
- nonpersonalMetadata not set to true (const constraint violated) — schema error
- Malformed or missing record projections — comparison cannot proceed
- Ambiguous pin definitions in supplied records — partial or inconclusive parity result

## 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 public dataset/observation/event/taxon/method Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a semantic parity verdict indicating whether the before and after ecology observation record projections are equivalent, along with details on any field or scope mismatches, while ignoring record order and preserving all declared pins.
