## 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.

### Resemble AI Text-to-Speech API

1. Check the voice's model before synthesis, since voices on pre-Ultra models fail until upgraded.
2. Keep each synchronous request under 2,000 characters.
3. Decode `audio_content` from base64 on `/synthesize`, or call `/stream` for raw WAV chunks.
4. Send `Authorization: Bearer`, since some doc examples leave out the prefix.
5. Log the request ID with every failure, since the error body has no code.
