## Verdicts

**Murf TTS API + MCP.** Falcon 2 costs 1 cent per 1,000 characters on pay as you go, with a $2 minimum purchase. Falcon 2 concurrency is 2 outside US-East on free and pay as you go, 5 on US-East.

**Rime TTS API + MCP.** Only character counts are kept by default, and customer data isn't used for training without an opt-in. No OpenAPI or AsyncAPI file and no official SDKs.

## Before you call either

### Murf TTS API + MCP

1. Send `locale` on every request, since `multiNativeLocale` was replaced on 2026-03-05.
2. Split text into chunks under 3,000 characters per request.
3. Use the US-East host for 5 concurrent Falcon 2 calls instead of 2.
4. Set `encodedAsBase64` to get audio inline and skip the expiring download link.
5. Back off on 429 and close WebSocket contexts with `end: true` to free slots.

### 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.
