# Air Quality Observations – Exact Row Deduplication

> Air Quality Observations – Exact Row Deduplication is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Identifies and removes exact duplicate rows from a supplied batch of air quality observation records (station, date, PM2.5, humidity).

## 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 air-quality-observations-exact-row-deduplication-05576ce4 -d '<json body>'
```

Example prompt: I have a batch of up to 200 air quality observation records with station name, date, PM2.5, and humidity — can you run exact row deduplication on them to remove any fully repeated entries and give me a clean unique set?

## When to prefer this

Use this endpoint when you have a bounded batch of up to 200 air quality observation records and need to identify or remove exact duplicate rows before analysis or storage. It is purpose-built for the specific schema of station/date/PM2.5/humidity data. Prefer this over general-purpose deduplication tools when working within the air quality monitoring domain and needing a lightweight, low-cost ($0.01 USDC) per-call operation with no side effects.

## Known failure modes

- Fewer than 1 row supplied returns a validation error
- More than 200 rows submitted exceeds the maxItems limit and is rejected
- Missing required fields (row_id, station, date, pm25, humidity_percent) cause schema validation failure
- Invalid date format (not YYYY-MM-DD) triggers pattern validation error
- Non-numeric values in pm25 or humidity_percent fields cause type errors

## How this service works

Air quality observations - Exact row deduplication: Exact row deduplication for Air quality observations. Up to 200 supplied typed records. Local descriptive analytics; no enrichment or forecast. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded exact row deduplication report.

## Output

A deduplication report identifying which of the supplied rows are exact duplicates, returning the unique set of air quality observation records (preserving row_id, station, date, pm25, humidity_percent) and flagging or removing redundant entries — local analytics only, no enrichment or forecasting.
