# Supplier Qualification — Daily Sum Series + Trailing Mean Series

> Supplier Qualification — Daily Sum Series + Trailing Mean Series 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 daily sum time series and trailing moving average series for supplier qualification metrics (checked_criteria, met_criteria) from supplied row data, returning two analytical reports.

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 supplier-qualification-daily-sum-series-trailing-mean-series-7f7cb55a -d '<json body>'
```

Example prompt: Take these 50 supplier qualification records with dates, company groups, checked_criteria and met_criteria values, and give me both the daily sum series and the trailing mean series for the met_criteria field using a window of 7 — I need two reports summarizing trends over time.

## When to prefer this

Choose this endpoint when you have supplier qualification records with dated criteria metrics and need both a daily aggregation and a smoothed trailing average in a single low-cost call. It is ideal for offline batch analysis of up to 200 rows of already-collected data where no live lookup or external data enrichment is needed. Prefer this over general analytics tools when you want a purpose-built, schema-validated computation for supplier qualification fields specifically.

## Known failure modes

- Input rows array is empty or exceeds 200 items — validation error
- date field does not match YYYY-MM-DD pattern — schema validation failure
- window value is less than 2 or greater than 200 — rejected input
- met_criteria or checked_criteria values outside allowed numeric range — schema error
- Missing required row fields (row_id, company_group, date) — request rejected
- Invalid field enum value (must be 'checked_criteria' or 'met_criteria') — error response

## How this service works

Supplier qualification — Daily sum series + Trailing mean series: Daily sum series + Trailing mean series for supplied supplier qualification records (checked_criteria, met_criteria). 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

Two independent analytical reports derived from the supplied rows: (1) a daily sum series showing the total of the selected field (checked_criteria or met_criteria) per day, and (2) a trailing mean series showing the rolling average over the specified window. Up to 200 rows are supported per call.
