# Air Quality Observations — Record Quality Audit + Exact Row Deduplication

> Air Quality Observations — Record Quality Audit + 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 2026-10-23).

Runs two analytical reports on supplied air quality observation records: a record quality audit and an exact row deduplication check, for up to 200 rows.

## 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-record-quality-audit-exact-row-deduplication-d415592d -d '<json body>'
```

Example prompt: Can you run a record quality audit and exact duplicate check on these air quality observations? I have up to 50 rows with fields like row_id, station_group, date, concentration, and observation_count — I want to know which records have quality issues and which are exact duplicates.

## When to prefer this

Choose this endpoint when you need both a data quality audit and exact duplicate detection on air quality observation records in a single call, with no need for live environmental data, predictions, or external lookups. Ideal for data pipeline validation steps before downstream analysis, when cost efficiency matters ($0.01 for two reports on up to 200 rows) and the data is already collected and structured.

## Known failure modes

- Exceeds 200-row limit — request rejected
- Missing required fields (row_id, station_group, date, concentration, observation_count) — validation error
- Malformed date format (not YYYY-MM-DD) — schema validation failure
- Empty rows array (minItems: 1 not met) — rejection
- Payment not received or insufficient USDC — 402 response
- Field values outside numeric bounds — schema rejection

## How this service works

Air quality observations — Record quality audit + Exact row deduplication: Record quality audit + Exact row deduplication for supplied air quality observations records (concentration, observation_count). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two independent analytical reports: (1) a record quality audit identifying issues such as null values, out-of-range values, or malformed fields across the supplied air quality observation rows; and (2) an exact row deduplication report listing which rows are exact duplicates of other rows. Both reports are computed locally using shared analytical engines with no external data lookups.
