# Controller Sampling — Exact Row Deduplication + Duplicate Key Report

> Controller Sampling — Exact Row Deduplication + Duplicate Key Report 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 controller sampling records by exact row match and generates a duplicate key report for up to 200 rows of input_latency_ms and sample_count data.

## 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 controller-sampling-exact-row-deduplication-duplicate-key-report-507ab04a -d '<json body>'
```

Example prompt: I have a batch of controller sampling records with fields like game_area, date, input_latency_ms, and sample_count — can you run exact row deduplication and give me a duplicate key report on them? Here are up to 200 rows: row-1, group-a, 2026-10-01, latency 10ms, sample_count 1; row-2, group-b, 2026-10-02, latency 20ms, sample_count 2.

## When to prefer this

Choose this endpoint when you have controller sampling records (with input_latency_ms and sample_count fields) and need both exact row deduplication and a duplicate key audit in a single low-cost call. It is ideal for data cleaning pipelines prior to game analytics, QA workflows flagging repeated submissions, or any scenario where you need two complementary data quality reports on up to 200 rows for $0.01 USDC without external dependencies.

## Known failure modes

- Input exceeds 200 rows — request rejected with validation error
- Missing required fields (row_id, date, game_area, input_latency_ms, sample_count) — row-level validation failure
- Date field not matching YYYY-MM-DD pattern — schema validation error
- Numeric fields out of allowed range (±1,000,000,000,000) — schema rejection
- Empty rows array — minimum item count violation

## How this service works

Controller sampling — Exact row deduplication + Duplicate key report: Exact row deduplication + Duplicate key report for supplied controller sampling records (input_latency_ms, sample_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) an exact row deduplication result identifying and removing fully duplicate rows from the supplied controller sampling records, and (2) a duplicate key report listing any row_id or key combinations that appear more than once. Both reports are generated locally without external lookups, covering up to 200 input rows.
