# API Usage Imports — CSV Cell Length Audit

> API Usage Imports — CSV Cell Length Audit is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Validates cell length constraints across all columns in a CSV of API usage import records, flagging any cells that exceed a specified maximum character length.

## 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-imports-csv-cell-length-audit-5525e1ef -d '<json body>'
```

Example prompt: Can you audit my API usage import CSV for cell length violations — use a max cell length of 200 characters, comma delimiter, and flag anything that goes over? Here's the CSV: usage_id,observed_on,endpoint_id,request_count,error_count\nrecord-a,2026-01-01,group-a,10,2

## When to prefer this

Choose this endpoint when you need to enforce character-length constraints on cells in an API usage CSV before importing or sharing the data. It is purpose-built for API usage import tables (with fields like usage_id, endpoint_id, request_count) and supports quoted cells, configurable delimiters, and category allow-listing in a single call for $0.01 USDC. Prefer it over generic CSV validators when the audit focus is specifically cell length compliance rather than schema inference, type checking, or statistical profiling.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV has fewer than 1 character — validation error
- max_cell_length out of allowed range (1–5000) — parameter error
- Delimiter not one of comma, semicolon, or tab — schema validation failure
- More than 100 allowed_categories supplied — parameter error
- Malformed CSV (unclosed quotes, inconsistent columns) — parsing error

## How this service works

API usage imports — Cell length audit: Cell length audit for API usage imports. Validate a declared CSV table contract, up to 1000 rows. Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV cell length audit report.

## Output

Returns a cell length audit report identifying which rows and cells in the submitted CSV exceed the specified max_cell_length, along with summary statistics on cell lengths across the dataset. Up to 1000 rows are supported per call.
