## 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-expand-api-a2e9420c -d '<json body>'
```

Example prompt: Take this short product description — 'Ergonomic chair with lumbar support' — and expand it into a detailed, professional marketing paragraph, aiming for about 150 words.

## When to prefer this

Choose this endpoint when you need to programmatically lengthen short text snippets into fuller content with style control and a target length, especially in automated agent workflows that pay per request via x402 on Base chain. Prefer it over general LLM completions when you want a simple, structured REST call that handles content expansion as a dedicated, pay-per-use service.

## Known failure modes

- Missing required 'text' field returns an error response with success: false
- Very long input text may cause truncation or timeout
- Invalid or unrecognized style values may be ignored or default to a neutral style
- Service may return success: false without descriptive error details due to minimal response schema
- Network or payment (x402) failures may prevent request completion

## How this service works
