# Account Research Coverage — Trailing Mean Series + Explicit Missing-Value Fill

> Account Research Coverage — Trailing Mean 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 2026-10-15).

Computes a trailing moving-average time series and fills missing values for account research coverage data (researched_accounts and target_accounts fields) 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 account-research-coverage-trailing-mean-series-explicit-missing-value-c19cc595 -d '<json body>'
```

Example prompt: Can you run a trailing mean series with a window of 3 and fill missing values using median on my account research coverage data? I have about 50 rows with company_group, date, researched_accounts, and target_accounts fields, and I want to analyze the researched_accounts metric.

## When to prefer this

Choose this endpoint when you have tabular account research or sales pipeline coverage data with a date dimension and need both a smoothed rolling average and missing-value imputation in a single call. It is ideal for small-to-medium datasets (up to 200 rows) grouped by company where you want local analytical computation without any external data lookups, predictions, or live integrations. Prefer this over general-purpose analytics services when you specifically need trailing mean smoothing combined with explicit null filling for account coverage metrics at low cost.

## Known failure modes

- Input array is empty or exceeds 200 rows — rejected with validation error
- Missing required fields (row_id, date, company_group) in any row — schema validation failure
- date field does not match YYYY-MM-DD format — pattern validation error
- window value is less than 2 or greater than 200 — out-of-range error
- field enum value is not 'researched_accounts' or 'target_accounts' — invalid enum error
- method enum is not 'zero', 'mean', or 'median' — invalid enum error
- Payment of 0.01 USDC not received — 402 Payment Required response

## How this service works

Account research coverage — Trailing mean series + Explicit missing-value fill: Trailing mean series + Explicit missing-value fill for supplied account research coverage records (researched_accounts, target_accounts). 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 submitted dataset: (1) a trailing moving-average series computed over the specified window for the chosen field, and (2) the same dataset with explicit missing-value imputation applied using the selected method (zero, mean, or median). Results cover up to 200 input rows with no external lookups or predictions.
