Technical details
Endpoint
GEThttps://agents.citiviewgroup.com/v1/speak?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost ($0.01/call) text-to-speech conversion returning a standard WAV file in one of six languages (English, Spanish, French, Chinese, Japanese, Korean) with no additional setup. It is callable via simple GET request, making it easy to integrate into agents or pipelines without complex authentication beyond x402 micropayment. Prefer alternatives if you need SSML markup, custom voices, audio format options beyond WAV, streaming, or languages outside the supported six.
Side effects
- Text exceeds 2000 character limit — request rejected or truncated
- Unsupported language code provided — error or fallback to default
- Empty text field — request fails validation
- Network timeout for longer synthesis jobs
- Malformed query parameters on GET request — 400 error
