## 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 scrapfly-content-retone-api-d1c103a3 -d '<json body>'
```

Example prompt: Can you rewrite this email in a more empathetic and warm tone? Here's the text: 'Your account has been suspended due to non-payment. Contact support immediately.'

## When to prefer this

Choose this endpoint when you need to quickly adjust the tone of existing text without manually rewriting it — particularly useful for repurposing content across audiences (formal vs casual), softening or strengthening communications, or adapting marketing copy for different brand voices. Prefer this over a general LLM call when you want a pay-per-use, agent-friendly microservice with predictable pricing via x402 on Base chain.

## Known failure modes

- Missing required 'text' field returns an error response with success: false
- Missing required 'target_tone' field causes a validation error
- Unsupported or unrecognized tone values may produce unexpected or generic output
- Insufficient USDC balance or x402 payment failure blocks the request entirely
- Very long input texts may be truncated or result in degraded output quality
