# Experiment Signals String Normalisation

> Experiment Signals String Normalisation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Normalises numeric experiment signal records (up to 200 rows) across conditions and dates, returning a bounded string normalisation report for local descriptive analytics.

## 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 experiment-signals-string-normalisation-c1c8b41b -d '<json body>'
```

Example prompt: Normalise my experiment signal data — I have 4 rows: row-1 on 2026-10-01 with signal 10 and background 1 in group-a, row-2 on 2026-10-02 with signal 20 and background 2 in group-b, row-3 on 2026-10-03 with signal 15 and background 3 in group-a, and row-4 on 2026-10-04 with signal 30 and background 4 in group-b, and I want a string normalisation report.

## When to prefer this

Use this endpoint when you have up to 200 experiment signal records with associated conditions and background values and need a lightweight, local string normalisation report without any external enrichment, forecasting, or enrichment dependencies. Ideal for descriptive analytics on A/B test or controlled experiment data where simple normalisation is sufficient.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, condition, date, signal, background) cause rejection
- Invalid date format (not YYYY-MM-DD) triggers a pattern validation error
- Signal or background values outside ±1,000,000,000,000 are rejected
- Empty rows array (minItems: 1 not met) returns an error

## How this service works

Experiment signals - String normalisation: String normalisation for Experiment signals. Up to 200 supplied typed records. Local descriptive analytics; no enrichment or forecast. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded string normalisation report.

## Output

A bounded string normalisation report covering the submitted experiment signal records, providing local descriptive analytics output including normalised signal values across the supplied conditions and dates. No external enrichment or forecasting is included.
