No OpenAPI or AsyncAPI file and no official SDKs. ## Before you call either ### PlayHT Text-to-Speech API 1. Don't call api.play.ht, it doesn't resolve. 2. Ignore docs.play.ht code samples, they describe a closed service. 3. Map PlayDialog or Play 3.0 Mini work to another TTS listing before writing code. ### Rime TTS API + MCP 1. Always send `modelId`, since a missing one routes to Mist v3 and Coda speakers then fail. 2. Keep HTTP requests under 1,000 characters or use the WebSocket. 3. Back off on 429 before reopening a WebSocket, and remember each retry bills again. 4. Use `/ws3` when you need word timestamps. 5. Keep the key server-side, since WebSockets take it in a header and there are no short-lived tokens. ## Other comparisons with PlayHT Text-to-Speech API or Rime TTS API + MCP - [Amazon Polly vs PlayHT Text-to-Speech API](https://www.anchorterminal.com/compare/amazon-polly-vs-playht-tts.md) - [Amazon Polly vs Rime TTS API + MCP](https://www.anchorterminal.com/compare/amazon-polly-vs-rime-tts.md) - [Azure AI Speech text-to-speech vs PlayHT Text-to-Speech API](https://www.anchorterminal.com/compare/azure-text-to-speech-vs-playht-tts.md) - [Azure AI Speech text-to-speech vs Rime TTS API + MCP](https://www.anchorterminal.com/compare/azure-text-to-speech-vs-rime-tts.md) - [Cartesia Sonic TTS API + MCP vs PlayHT Text-to-Speech API](https://www.anchorterminal.com/compare/cartesia-tts-vs-playht-tts.md) - [Cartesia Sonic TTS API + MCP vs Rime TTS API + MCP](https://www.anchorterminal.com/compare/cartesia-tts-vs-rime-tts.md) - [Deepgram Text-to-Speech (Aura-2, Flux TTS) vs PlayHT Text-to-Speech API](https://www.anchorterminal.com/compare/deepgram-tts-vs-playht-tts.md) - [Deepgram Text-to-Speech (Aura-2, Flux TTS) vs Rime TTS API + MCP](https://www.anchorterminal.com/compare/deepgram-tts-vs-rime-tts.md) - [ElevenLabs Text to Speech API + MCP vs PlayHT Text-to-Speech API](https://www.anchorterminal.com/compare/elevenlabs-tts-vs-playht-tts.md) - [ElevenLabs Text to Speech API + MCP vs Rime TTS API + MCP](https://www.anchorterminal.com/compare/elevenlabs-tts-vs-rime-tts.md) - [Murf TTS API + MCP vs PlayHT Text-to-Speech API](https://www.anchorterminal.com/compare/murf-tts-vs-playht-tts.md) - [Murf TTS API + MCP vs Rime TTS API + MCP](https://www.anchorterminal.com/compare/murf-tts-vs-rime-tts.md) - [PlayHT Text-to-Speech API vs Resemble AI Text-to-Speech API](https://www.anchorterminal.com/compare/playht-tts-vs-resemble-ai-tts.md) - [PlayHT Text-to-Speech API vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/playht-tts-vs-soniox-tts.md) - [Resemble AI Text-to-Speech API vs Rime TTS API + MCP](https://www.anchorterminal.com/compare/resemble-ai-tts-vs-rime-tts.md) - [Rime TTS API + MCP vs Soniox Text-to-Speech](https://www.anchorterminal.com/compare/rime-tts-vs-soniox-tts.md)
