## 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 subscription-request-exact-normalised-duplicate-audit-371fcddb -d '<json body>'
```

Example prompt: Can you audit my subscription request dataset for exact normalised duplicates? I have about 50 labelled records — some marked as upgrade, some cancel, some renew, some downgrade — and I want to know which ones are duplicates after normalisation.

## When to prefer this

Choose this endpoint when you need a lightweight, inexpensive exact normalised duplicate check on a small batch of labelled subscription request text records (up to 200) — particularly useful before training or evaluating a text classifier to ensure dataset integrity. Prefer this over general-purpose deduplication tools when your data specifically involves subscription intent labels (upgrade, downgrade, cancel, renew) and you want a structured audit deliverable without deploying a hosted model.

## Known failure modes

- Fewer than 2 records supplied — minimum item count not met
- More than 200 records supplied — exceeds maximum batch size
- Record missing required fields (id, text, actual) — validation error
- Invalid enum value for 'actual' field (must be upgrade, downgrade, cancel, or renew)
- Record ID exceeds 80 characters or is empty — schema violation
- Text field exceeds 1000 characters per record — truncation or rejection
- Payment not processed via x402 protocol — request blocked
