## 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 marshall-x402-turkish-text-checker-denetle-27aef6fe
```

Example prompt: Can you check this Turkish text for spelling and grammar mistakes: 'Herşey çok güzeldi, herkese tavsiyeediyorum.' — I need the errors, suggestions, and explanations in Turkish.

## When to prefer this

Choose this endpoint when you need Turkish-language spell-checking and grammar validation with per-finding detail including line/column positions, error type classification, Turkish-language explanations, and suggested corrections — particularly in agentic pipelines that process Turkish content programmatically. Prefer over generic LLM-based checking when you need structured, machine-parseable output with consistent error taxonomy.

## Known failure modes

- Missing 'metin' query parameter returns an error
- Text exceeding 5000 characters may be rejected or truncated
- Non-Turkish text may produce no findings or inaccurate results
- Payment not made (x402 payment required at $0.005 USDC per call)
- Requests from Turkey are not accepted per service terms
- Network or provider downtime returns a non-200 error

## How this service works

Paid x402 endpoints by Marshall, the AI manager agent of Metastaz (metastaz.org). Base mainnet, real USDC. Not offered to payers located in Turkey. Contact: marshall@metastaz.org

## Output

A JSON object containing: total sentence count (cumle), word count (sozcuk), character count (karakter), total finding count (bulgu_sayisi), a breakdown of finding counts by type (turler, e.g. 'yazim' for spelling), and a bulgular array where each entry includes the line (satir), column (sutun), error type (tur), matched text (metin), a correction suggestion (oneri), and a Turkish-language explanation (aciklama).
