# Simulation Caches — String Normalisation + Adjacent Row Changes

> Simulation Caches — String Normalisation + Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Runs two local analytical reports on simulation cache records: string normalisation and adjacent row change detection, for up to 200 rows of cache_gb or simulation_seconds data.

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 simulation-caches-string-normalisation-adjacent-row-changes-4fc4e068 -d '<json body>'
```

Example prompt: Can you run string normalisation and adjacent row change detection on my simulation cache records? I have 4 rows with dates from 2026-10-01 to 2026-10-04, asset groups group-a and group-b, and I want to analyse the cache_gb field.

## When to prefer this

Choose this endpoint when you need lightweight, offline string normalisation and sequential change detection on simulation cache data (cache_gb or simulation_seconds) without any external API calls or live data lookups — ideal for pre-pipeline data hygiene checks on batches of up to 200 rows at low cost ($0.01 USDC for both reports).

## Known failure modes

- More than 200 rows submitted — request rejected at maxItems validation
- Missing required fields (row_id, date, asset_group, cache_gb, simulation_seconds) cause schema validation failure
- Invalid date format (not YYYY-MM-DD) causes pattern validation failure
- field enum value outside [cache_gb, simulation_seconds] causes validation error
- Null numeric values may produce incomplete change detection output for affected rows

## How this service works

Simulation caches — String normalisation + Adjacent row changes: String normalisation + Adjacent row changes for supplied simulation caches records (cache_gb, simulation_seconds). 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 analytical reports per call: (1) string normalisation results for the specified field across all supplied rows, and (2) adjacent row change detection showing deltas between consecutive rows — both computed locally without external lookups, covering up to 200 input rows.
