# Broken Link Observations — String Normalisation + Base-100 Series

> Broken Link Observations — String Normalisation + Base-100 Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Performs string normalisation and base-100 indexed series analysis on user-supplied broken link observation records (checked_links, broken_links) for up to 200 rows, returning 2 analytical reports.

## 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 broken-link-observations-string-normalisation-base-100-series-569008f2 -d '<json body>'
```

Example prompt: Analyse my broken link data for the past week — I have rows for site groups 'group-a' and 'group-b' with checked_links and broken_links counts per day. Run string normalisation and a base-100 series on the broken_links field, using row index 0 as the base, for all 4 rows.

## When to prefer this

Choose this endpoint when you have up to 200 rows of broken link observation data with checked_links and broken_links counts and need both string normalisation of categorical fields (like site_group) and a base-100 time-indexed series for trend analysis — all without requiring any live web lookup, external data, or prediction. It is especially useful for offline post-hoc analysis of crawl or audit exports at very low cost ($0.01 USDC for both reports).

## Known failure modes

- Empty or missing rows array returns an error
- More than 200 rows submitted exceeds the limit and is rejected
- Invalid date format (not YYYY-MM-DD) fails schema validation
- base_index value outside the range 0–199 is rejected
- Non-numeric values in checked_links or broken_links (when not null) cause computation errors
- Invalid field enum value (not 'checked_links' or 'broken_links') causes rejection
- Payment not attached or insufficient USDC causes x402 payment required response

## How this service works

Broken link observations — String normalisation + Base-100 series: String normalisation + Base-100 series for supplied broken link observations records (checked_links, broken_links). 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 2 analytical reports: (1) a string normalisation report cleaning and standardising string fields such as site_group across all supplied rows, and (2) a base-100 indexed series for the selected numeric field (checked_links or broken_links), rebased at the specified base_index row, covering up to 200 rows of broken link observation data.
