# Endpoint Telemetry — Record Quality Audit + Explicit Missing-Value Fill

> Endpoint Telemetry — Record Quality Audit + 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 2026-11-02).

Audits data quality and fills missing values (via zero, mean, or median) in endpoint telemetry records containing agent_count and reporting_agents fields, returning two independent 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 endpoint-telemetry-record-quality-audit-explicit-missing-value-fill-605a5c38 -d '<json body>'
```

Example prompt: Run a record quality audit and fill any missing agent_count values using the median method on my telemetry data — I have 4 rows with dates from 2026-10-01 to 2026-10-04, control groups group-a and group-b, agent counts of 10, 20, null, and 30, and reporting_agents of 1, 2, 3, and 4.

## When to prefer this

Choose this endpoint when you need to both audit data quality AND impute missing values in endpoint telemetry data (agent_count or reporting_agents fields) in a single call at low cost ($0.01 USDC for both reports). It is best suited for small-to-medium batches (up to 200 rows) of structured telemetry with date, control group, and numeric agent fields. Prefer this over general-purpose data tools when you specifically need the two-report combined output (audit + fill) for agent monitoring telemetry. Not suitable when you need live data lookup, prediction, or external enrichment.

## Known failure modes

- Rows array exceeds 200 items — request rejected
- Invalid date format (not YYYY-MM-DD) — validation error
- Unknown fill method outside zero/mean/median enum — schema error
- Field value outside allowed numeric range (-1e12 to 1e12) — validation error
- Empty rows array (minItems: 1 violated) — schema error
- row_id missing or empty string — required field error

## How this service works

Endpoint telemetry — Record quality audit + Explicit missing-value fill: Record quality audit + Explicit missing-value fill for supplied endpoint telemetry records (agent_count, reporting_agents). 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 reports: (1) a record quality audit identifying completeness issues, nulls, and anomalies in the telemetry rows, and (2) an explicit missing-value fill report showing which records had the specified field (agent_count or reporting_agents) filled using the chosen method (zero, mean, or median), with the imputed values included. Both reports are computed locally with no external lookups.
