# Business Directory Coverage — Daily Sum Series + Missing Value Fill

> Business Directory Coverage — Daily Sum Series + 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 2026-10-20).

Computes daily sum time series and fills missing values for business directory coverage metrics (listed_entities, verified_entities) across 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 business-directory-coverage-daily-sum-series-missing-value-fill-d751e552 -d '<json body>'
```

Example prompt: I have daily business directory records for two company groups across 4 dates with listed_entities and verified_entities counts — some values are missing. Can you compute the daily sum series and fill the missing values using the median method for the listed_entities field?

## When to prefer this

Choose this endpoint when you have tabular business directory coverage data (listed and verified entity counts) already in hand and need offline aggregation into a daily sum time series combined with missing-value imputation — no live data lookup or external enrichment required. It is ideal for batch analytical pipelines processing up to 200 rows per call at minimal cost ($0.01 USDC for both reports).

## Known failure modes

- Input array exceeds 200 rows — request is rejected
- Missing required fields (row_id, date, company_group) cause validation errors
- Invalid date format (not YYYY-MM-DD) causes parsing failure
- Unsupported fill method enum value causes schema validation error
- Empty rows array (minItems:1 violated) returns error
- Numeric values outside allowed range (-1e12 to 1e12) are rejected

## How this service works

Business directory coverage — Daily sum series + Explicit missing-value fill: Daily sum series + Explicit missing-value fill for supplied business directory coverage records (listed_entities, verified_entities). 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 daily sum series aggregating the chosen metric by date and company group, and (2) the same dataset with explicit missing-value fills applied using the selected method (zero, mean, or median). Up to 200 rows processed per call.
