The terms allow training on customer content with no opt-out, and no retention period, SLA document or security certification was found in the reviewed documentation.\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. Falcon 2 concurrency is 2 outside US-East on free and pay as you go, 5 on US-East.\n\n## Before you call either\n\n### Fish Audio TTS API\n\n1. Send the `model` header on every request and check its spelling. A missing or unknown value is served and billed as `s2.1-pro`.\n2. Budget by UTF-8 bytes, not characters. Chinese, Japanese and Korean text costs about three bytes a character.\n3. Retry 429 and 5xx with exponential backoff. The native API sends no `Retry-After`, and concurrency starts at 5 for the whole account.\n4. Use `[bracket]` cues on the S2 family. `(parenthesis)` tags from `s1` are read aloud as text.\n5. Pass the model explicitly in the JavaScript SDK, because npm release 0.1.0 defaults to `s1`.\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, Fish Audio TTS API or Murf TTS API + MCP?\n\nMurf TTS API + MCP scores 70.6 (BB) on agent readiness against Fish Audio TTS API's 60.7 (C), and leads in 6 of 7 scored categories. Fish Audio TTS API leads on maintenance \u0026 community.\n\n### Do Fish Audio TTS API and Murf TTS API + MCP need an API key?\n\nFish Audio TTS API takes an API key or an OAuth sign-in. Murf TTS API + MCP needs an API key.\n\n### Can an agent call Fish Audio TTS API and Murf TTS API + MCP without installing anything?\n\nYes. Fish Audio TTS API has a hosted endpoint at https://api.fish.audio and Murf TTS API + MCP at https://api.murf.ai/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/fish-audio-tts-vs-murf-tts.json, and with the fewest tokens: https://www.anchorterminal.com/compare/fish-audio-tts-vs-murf-tts.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"fish-audio-tts\", \"b\": \"murf-tts\"}`.
