## 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 csv-dialect-sniffer-structure-analyzer-6fb9de3e -d '<json body>'
```

Example prompt: Can you sniff the dialect of this CSV text and tell me how many rows and columns it has? Here's the data: 'name;age;city\nAlice;30;London\nBob;25;Paris'

## When to prefer this

Use this endpoint when you need a deterministic, rule-based CSV dialect detection without relying on an LLM to guess the format. Prefer it over manual inspection or LLM inference when accuracy and reproducibility matter. Note: the description recommends trying the unpaid POST /v1/sandbox/csv-sniff first to avoid the $0.003 USDC charge when testing.

## Known failure modes

- Text too short or malformed to detect a consistent dialect
- Input exceeds 100,000 character limit, resulting in a rejection
- Text is not CSV-like at all (e.g. plain prose), leading to ambiguous or incorrect dialect detection
- Empty string input rejected due to minLength:1 constraint
- Payment not processed, returning 402 Payment Required — use the free /v1/sandbox/csv-sniff endpoint first

## How this service works

Call when an agent needs the sniffed CSV dialect plus column and row counts. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/csv-sniff first.

## Output

Returns the detected CSV dialect including delimiter character, quoting style, and line ending convention, along with the total column count and row count parsed from the submitted text.
