## 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 research-sample-recovery-exact-row-deduplication-73dc7660 -d '<json body>'
```

Example prompt: I have a batch of up to 200 research sample recovery records — each with a row ID, specimen name, date, input mass in grams, and recovered mass in grams — and I need you to strip out any exact duplicate rows and give me a deduplication report.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) exact row deduplication specifically for research sample recovery records with typed mass and specimen fields. It is best suited for batches up to 200 records requiring local descriptive analytics without any enrichment, forecasting, or fuzzy matching — ideal for cleaning lab exports or merged specimen logs before downstream analysis.

## Known failure modes

- Fewer than 1 row provided — validation error
- More than 200 rows submitted — rejected with item count limit error
- Missing required fields (row_id, specimen, date, input_mass_g, recovered_mass_g) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Non-numeric value for mass fields — type validation error
- Payment not completed or insufficient USDC — 402 payment required
