# Air Quality Observations — Exact Row Deduplication + Keyed Dataset Comparison

> Air Quality Observations — Exact Row Deduplication + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Deduplicates air quality observation rows and compares two supplied datasets by key, returning two analytical reports on concentration and observation_count fields.

## 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-keyed-dataset-2ee2018a -d '<json body>'
```

Example prompt: I have two batches of air quality observation records — each up to 200 rows with fields like row_id, station_group, date, concentration, and observation_count — can you deduplicate each batch and compare them row-by-row to find any differences in the concentration or observation_count values?

## When to prefer this

Choose this endpoint when you have air quality observation records (with concentration and observation_count fields) and need to either find exact duplicate rows within a single dataset or compare two datasets by row key to detect value differences — all using supplied data only, with no external API calls, predictions, or live data lookups. It processes up to 200 rows and returns two reports in a single call for $0.01 USDC.

## Known failure modes

- More than 200 rows submitted — payload rejected or truncated
- Missing required fields (row_id, station_group, date, concentration, observation_count) — validation error
- Invalid date format (must match YYYY-MM-DD pattern) — schema validation failure
- Empty rows array submitted — minimum 1 item required
- Numeric fields out of accepted range — schema rejection
- Payment not included or insufficient — x402 payment required error

## How this service works

Air quality observations — Exact row deduplication + Keyed dataset comparison: Exact row deduplication + Keyed dataset comparison 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

Two analytical reports: (1) an exact row deduplication report identifying duplicate records within the supplied dataset, and (2) a keyed dataset comparison report showing row-by-row differences between the two supplied datasets on concentration and observation_count fields, based entirely on the data you provide with no external lookups.
