# Biology Assays Export Semantic Parity

> Biology Assays Export Semantic Parity is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.039312/call, status unknown (last checked 2026-11-04).

Compares two sets of parsed biology assay export records (before/after) for semantic parity, ignoring array order but preserving pins and scope, to detect meaningful content changes.

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 biology-assays-export-semantic-parity-f853d2d7 -d '<json body>'
```

Example prompt: Compare these two sets of biology assay export records — up to 32 records each in the before and after arrays — and tell me if they're semantically equivalent (ignoring array order but checking all pins and scope); use the 'synthetic' data class and flag that this is non-personal metadata.

## When to prefer this

Use this endpoint when you need to confirm semantic equivalence of biology assay export records across two snapshots or pipeline stages, specifically when array ordering may differ but meaningful content, pins, and scope must match exactly. Prefer this over raw byte-equality checks or artifact-level hashing when the concern is parsed record content rather than file identity, and over general diff tools when biology assay domain semantics (scope labels, pins, study/batch/protocol structure) must be respected.

## Known failure modes

- Array exceeds 32-item limit — request rejected with validation error
- dataClass value outside 'public' or 'synthetic' enum — schema validation failure
- nonpersonalMetadata not set to true (const) — request rejected
- Malformed or unparseable records in before/after arrays — comparison cannot proceed
- Empty arrays on both sides — trivially equal result with no useful diff information

## 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 assay study/batch/protocol/export 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 biology assay record arrays are equivalent when parsed and compared without regard to ordering, including details on any pin or scope mismatches, content-level differences, and which records changed meaningfully versus those that only shifted position.
