## 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 assay-unit-conversion-audit-1af5a95e -d '<json body>'
```

Example prompt: Can you audit these 12 assay volume records — some are declared in mL and some in µL — and flag any that are inconsistent with each other using exact integer microunit ratios? Mark the data as synthetic and nonpersonal.

## When to prefer this

Choose this endpoint when you need a lightweight, offline, typed-metadata-only audit of declared assay volumes in L, mL, or µL using exact integer microunit ratios — without any concentration, potency, clinical dosing, or measurement-validity inference. Ideal for QC pipelines handling up to 32 records at a time on public or synthetic nonpersonal data.

## Known failure modes

- Records array empty or exceeds 32-item limit — validation error
- nonpersonalMetadata not set to true — rejected
- dataClass not one of 'public' or 'synthetic' — schema validation failure
- Malformed volume records with missing or unrecognized units — processing error
- Exceeds retained-result recovery window (>24h) for result retrieval

## How this service works

Compare declared assay volumes in L, mL or uL using exact integer microunit ratios. No concentration, potency, clinical dosing or measurement-validity inference. Offline typed metadata only. Retained-result recovery: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns an audit report indicating whether declared assay volumes across submitted records are consistent when compared using exact integer microunit ratios, with flags identifying any records where unit declarations disagree. Retained results are recoverable for 24 hours; minimal receipt metadata is retained for 90 days.
