# Coordinate Quality Checks — Daily Sum Series + Explicit Missing-Value Fill

> Coordinate Quality Checks — Daily Sum Series + Explicit Missing-Value Fill is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Computes daily sum time series and fills missing values (zero, mean, or median) for coordinate quality check records with checked_points and flagged_points fields, producing two analytical reports for up to 200 rows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 coordinate-quality-checks-daily-sum-series-explicit-missing-value-fill-2fb5fe05 -d '<json body>'
```

Example prompt: I have up to 200 rows of coordinate quality check records with date, station_group, checked_points, and flagged_points — can you run a daily sum series and fill any missing flagged_points values using the median method, and give me two analytical reports?

## When to prefer this

Choose this endpoint when you have pre-collected coordinate quality check records (checked_points, flagged_points) per station group per date and need both a daily sum time series and explicit missing-value imputation in a single low-cost call ($0.01 USDC for two reports, up to 200 rows). It is a purely analytical, offline computation with no live data lookup, external calls, or side effects — ideal for batch QC auditing workflows where data is already gathered.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, checked_points, flagged_points) cause row-level errors
- Invalid date format (not YYYY-MM-DD) causes parsing failure
- Invalid method enum value (not zero/mean/median) causes validation error
- Invalid field enum value (not checked_points/flagged_points) causes validation error
- Payment of 0.01 USDC not settled — request blocked

## How this service works

Coordinate quality checks — Daily sum series + Explicit missing-value fill: Daily sum series + Explicit missing-value fill for supplied coordinate quality checks records (checked_points, flagged_points). 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 analytical reports for the supplied coordinate quality check records: (1) a daily sum time series aggregating the target field (checked_points or flagged_points) by date, and (2) a dataset with missing values explicitly filled using the chosen method (zero, mean, or median). Covers up to 200 input rows per call.
