## 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 api-usage-string-normalisation-5f73c96f -d '<json body>'
```

Example prompt: Can you normalise the string fields in my API usage records? I have about 50 rows with endpoint names like 'group-a' and 'group-b', dates in YYYY-MM-DD format, plus request counts and latency values — they need to be cleaned up and standardised before I run my analytics.

## When to prefer this

Choose this endpoint when you have API usage records with inconsistent or messy string fields — particularly endpoint names and dates — and need a lightweight, local normalisation pass before analytics. It handles up to 200 records per call at very low cost ($0.01 USDC) and performs no external enrichment, making it ideal for deterministic, repeatable data cleaning steps in an analytics pipeline.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, endpoint, date, requests, latency_ms) causes record rejection
- Invalid date format (not YYYY-MM-DD) may result in processing error
- Numeric fields outside allowed range trigger validation failure
- Empty rows array returns an error

## How this service works

API usage - String normalisation: String normalisation for API usage. Up to 200 supplied typed records. Local numeric and data-quality processing; no external enrichment or forecasting. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded string normalisation deliverable.

## Output

Returns up to 200 API usage records with string fields (endpoint names, dates) normalised and cleaned — standardised casing, trimmed whitespace, consistent formatting — ready for downstream analytics or reporting pipelines.
