# Specification Traceability — String Normalisation + Daily Sum Series

> Specification Traceability — String Normalisation + Daily Sum Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Runs two local analytical reports on specification traceability data: string normalisation of document groups and a daily sum time series for mapped or total requirements (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 specification-traceability-string-normalisation-daily-sum-series-a37d8d8f -d '<json body>'
```

Example prompt: Normalize the document group names and compute a daily sum series for mapped_requirements using my spec traceability records: [{"date":"2026-10-01","row_id":"row-1","document_group":"group-a","total_requirements":5,"mapped_requirements":12},{"date":"2026-10-02","row_id":"row-2","document_group":"group-b","total_requirements":8,"mapped_requirements":20}].

## When to prefer this

Choose this endpoint when you need both string normalisation of categorical labels and a date-based cumulative sum series on specification traceability records in a single low-cost call, without requiring any external data sources, live lookups, or professional domain assessment.

## Known failure modes

- Missing required fields (row_id, date, document_group) cause validation errors
- Date strings not matching YYYY-MM-DD pattern are rejected
- Exceeding 200 rows returns an error or truncation
- Null values in the selected numeric field may be excluded from daily sums
- Invalid field enum value (not mapped_requirements or total_requirements) causes rejection

## How this service works

Specification traceability — String normalisation + Daily sum series: String normalisation + Daily sum series for supplied specification traceability records (mapped_requirements, total_requirements). 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 reports: (1) a string-normalised representation of document group labels across the supplied rows, and (2) a daily sum time series of the selected numeric field (mapped_requirements or total_requirements), computed purely from the supplied data with no external lookups.
