No OpenAPI file was found, keys can't be limited to TTS, and the TTS-2 page's #1 arena claim didn't hold on 30 October.\n\n**Murf TTS API + MCP.** Falcon 2 costs 1 cent per 1,000 characters on pay as you go, with a $2 minimum purchase.

Send the copied Base64 credential as-is in `Authorization: Basic`. Don't encode it again.\n2. Set `modelId` explicitly, because SDK defaults may name deprecated models.\n3. Keep text under 2,000 UTF-16 units on `/tts/v1/voice` and 4,000 on `voice:stream`, or use an async job.\n4. Turn on Reasoning with `synthesisContext.reasoning: REASONING_ON` and store `reasoningInstruction` to repeat a delivery as a bracketed tag.\n5. On 429 or error code 8, back off exponentially with jitter. No Retry-After header is documented.\n\n### Murf TTS API + MCP\n\n1. Send `locale` on every request, since `multiNativeLocale` was replaced on 2026-03-05.\n2. Split text into chunks under 3,000 characters per request.\n3. Use the US-East host for 5 concurrent Falcon 2 calls instead of 2.\n4. Set `encodedAsBase64` to get audio inline and skip the expiring download link.\n5. Back off on 429 and close WebSocket contexts with `end: true` to free slots.\n\n## Questions\n\n### Which is better for AI agents, Inworld Realtime TTS-2 or Murf TTS API + MCP?\n\nMurf TTS API + MCP scores 70.8 (BB) on agent readiness against Inworld Realtime TTS-2's 58.3 (C), and leads in 5 of 7 scored categories.
