Markdown https://www.anchorterminal.com/tools/murf-tts.md · JSON https://www.anchorterminal.com/api/v1/tools/murf-tts.json\n- Best text-to-speech APIs for AI agents: https://www.anchorterminal.com/best/text-to-speech/index.md\n- All 148 tts comparisons: https://www.anchorterminal.com/compare/text-to-speech/index.md\n\n## Which one, for what\n\n### MiniMax Speech (T2A) (C)\n\nGood for: Multilingual speech for narration and agents at mid-range prices, with strong Chinese voices by the vendor's account.\n\nAlso in its favour:\n- No incidents deducted, where Murf TTS API + MCP loses 3 points for them\n\nWatch for: No free allowance for synthesis and no official SDK\n\n### Murf TTS API + MCP (B)\n\nGood for: Budget voice-agent output where 2 to 5 concurrent streams are enough, or for studio-style renders on Gen2.\n\nAhead on:\n- Reliability, 90 against 75\n- Agent ergonomics, 71 against 56\n- Security \u0026 auth, 68 against 36\n- Payments \u0026 pricing, 40 against 20\n- Maintenance \u0026 community, 73 against 38\n\nAlso in its favour:\n- A hosted endpoint, with nothing to install\n- Runs on your own machine\n\nWatch for: Falcon 2.1 concurrency is 2 outside US-East on free and pay as you go, 5 on US-East\n\n\n## Why the edge\n\n### Maintenance \u0026 community: Murf TTS API + MCP +35\n\n- MiniMax Speech (T2A) (38): Read as a model, as minimax-voice-cloning is. The newest dated change touching speech is the MCP servers' August update, `minimax-mcp-js` 0.0.18 on 21 August 2026, 77 days before 6 November, and Speech 2.8 dates from 23 January 2026 (20 of 30). No dated API entries in the last 90 days (0). Support by email and Discord, not tested (6 of 15). No official SDK for speech; the MCP servers expose `text_to_audio` and `list_voices` (8 of 15). The Python MCP server has tests and moved to version 2 of the MCP SDK in August, with no CI workflow (4 of 10). Total 38.\n- Murf TTS API + MCP (73): Read as a model. Newest changelog entry 2026-10-27 (List Voices takes a model), after Falcon 2.1 on 2026-10-19 (30). Seven dated changelog entries in the 90 days from 3 August, on 5, 9, 13, 15, 19, 22 and 27 October, plus `murf-mcp` 0.1.14 on 2026-08-20 (10). Gen2 streaming was switched off on 2026-10-05 after a 20 July notice that named only the 16 August deprecation date, and on 19 October `falcon-2` began serving Falcon 2.1, announced the same day (0 of 10). Public changelog and a help centre (10 of 15). The Python SDK had no open issues on 1 October, per that check, not re-read on 1 November (8 of 10). Official SDK in Python only, 2.3.0 still the newest tag on 1 November, from 2026-03-05 (8 of 15). Fern-generated with a CI workflow, Python 3.8 and later (7 of 10). 30+10+0+10+8+8+7 = 73.\n\n### Security \u0026 auth: Murf TTS API + MCP +32\n\n- MiniMax Speech (T2A) (36): Model reading of the checklist, with training and retention in place of the least-privilege and injection lines. Plain API keys with no scopes found, and leaked keys may be disabled (20 of 30). The terms (effective 30 March 2026), as read for minimax-voice-cloning on 4 November, let MiniMax use input and generated content to operate, maintain, develop and improve its services, with no opt-out found, and the privacy policy rules out only training to profile or target consumers (5 of 20). The speech docs call every interface stateless, and no retention period for submitted text or generated audio was found (5 of 15). Responses carry `usage_characters` and a trace ID, with no audit log (6 of 15). No security.txt, disclosure policy, bug bounty or certification found (0 of 20). Total 36.\n- Murf TTS API + MCP (68): Model reading of the checklist, with training and retention in place of least-privilege and injection lines. One `api-key` header, plus a generate-token endpoint for short-lived client tokens. No key scopes found (23 of 30). The docs say customer text and audio never feed Murf's model training (20). Download links last 72 hours by the TTS overview and 24 hours by the Enterprise FAQ, and `encodedAsBase64` returns audio with nothing stored, so zero retention is self-serve but not the default (10 of 15). The dashboard shows daily and monthly usage, not per-call logs (5 of 15). SOC 2 Type II, ISO 27001 and ISO 42001 on the security page. No security.txt, disclosure policy or bug bounty found (10 of 20).\n\n### Payments \u0026 pricing: Murf TTS API + MCP +20\n\n- MiniMax Speech (T2A) (20): No x402, MPP or L402 (0). Per-character prices for every speech model published without a login (20). No free allowance for synthesis is published (0). A person signs up in a browser and funds a balance (0). Total 20.\n- Murf TTS API + MCP (40): No x402, MPP or L402 (0). Falcon 2 at 1 cent per 1,000 characters and Gen2 at $0.03, published in the docs without a login (20). 100,000 free characters with no time limit behind a Get Free API Key button. We found no card step in the docs or FAQ (20). A person signs up in a browser to get the key (0).\n\n### Reliability: Murf TTS API + MCP +15\n\n- MiniMax Speech (T2A) (75): Atlassian Statuspage at status.minimax.io with a Text-to-Speech component (20). Its history, re-read on 6 November, shows three incidents in the 90 days from 8 August, all titled elevated errors and labelled major, 22 minutes on 28 September, 3 minutes on 16 October and 2 minutes on 19 October, and none in November. Elevated errors with no fuller scope are read as partial, as on minimax-api and minimax-voice-cloning, so minor only (20). T2A is limited to 60 requests a minute, with higher limits on audio subscriptions (15). Error codes 1002 and 2045 say to retry later and avoid sudden increases, with no Retry-After or backoff figures (10 of 15). No SLA (0). No beta or preview label on T2A (10). 20 + 20 + 15 + 10 + 0 + 10 = 75.\n- Murf TTS API + MCP (90): Atlassian status page at murf.statuspage.io, linked from the rate-limits doc, with history back to February 2024 (20). No incident posted since 2025-09-22, still so on 1 November 2026, so the 90-day record is clean. The page tracks only two components (API and Studio), so a clean record says less than a page with a component per region (30). Concurrency limits published per model and region, 5 on US-East and 2 elsewhere for Falcon 2.1 on free and pay as you go, and since 22 October Falcon 2.1 streaming responses report the region, limit and slots in use (15). The errors page tells you to retry 429, 500 and 503 with exponential backoff (15). No SLA found on any self-serve tier (0). Falcon 2.1 carries no beta label (10).\n\n### Agent ergonomics: Murf TTS API + MCP +15\n\n- MiniMax Speech (T2A) (56): API reading of the checklist. Audio comes back hex-encoded inside JSON by default, with subtitles opt-in and format, bitrate and sample rate settable (15 of 25). Voices are listed by type through `POST /v1/get_voice`, which has no pagination and returns 300+ system voices for `all` (10 of 20). Errors come as numeric codes in `base_resp` with a short remedy for each, inside responses documented only as 200 (13 of 20). No idempotency key, and the MCP tools carry no read-only or destructive annotations (10 of 20). Two required fields. No official SDK for speech, with MCP servers in Python and JavaScript (8 of 15). Total 56.\n- Murf TTS API + MCP (71): Read as an API. Output in MP3, WAV, FLAC, A-law, mu-law or Base64 at 8 to 48 kHz, with word timestamps, streaming over HTTP or WebSocket, and inline Base64 instead of a download link (22 of 25). Per-request cap of 3,000 characters documented and the voice list filters by model, but there's no length control beyond splitting text yourself (12 of 20). Machine-readable error and warning codes with a `trace_id` (18 of 20). Backoff guidance documented (10). Nothing found on whether failed calls are billed and no seed for repeatable output (0 of 10). Three required fields including `locale`, and the only official SDK is Python (9 of 15).\n\n## Score by category\n\n| Category | Weight | MiniMax Speech (T2A) | Murf TTS API + MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 75 | 90 | Murf TTS API + MCP +15 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 81 | 85 | Murf TTS API + MCP +4 |\n| Agent ergonomics | 13% (16.2 this run) | 56 | 71 | Murf TTS API + MCP +15 |\n| Security \u0026 auth | 14% (17.5 this run) | 36 | 68 | Murf TTS API + MCP +32 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 40 | Murf TTS API + MCP +20 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 38 | 73 | Murf TTS API + MCP +35 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 65 | 67 | Murf TTS API + MCP +2 |\n| Negative events | ≤15 | 0 | -3 | |\n| **Total** | | **55.1 · C** | **69.5 · B** | |\n\n## Facts side by side\n\n| Fact | MiniMax Speech (T2A) | Murf TTS API + MCP |\n| --- | --- | --- |\n| Kind | Model API | Model API |\n| Vendor | MiniMax | Murf |\n| Hosted endpoint | no (local only) | `https://api.murf.ai/v1` |\n| Transports | HTTP, websocket | HTTP, stdio |\n| Auth | API key | API key |\n| Pricing | Pay per use | Freemium |\n| x402 | no | no |\n| Licence | none | MIT (SDK and MCP server) |\n| Tools exposed | 0 | none |\n| Read-only variant documented | no | no |\n| llms.txt | yes | yes |\n| Last release | 2026-01-23 | 2026-08-20 |\n| Terms last updated | couldn't be read | no date given |\n| Privacy policy last updated | couldn't be read | no date given |\n| Customer content may train models | couldn't be read | not found in the text |\n| Terms restrict automated access | couldn't be read | yes |\n| Terms restrict benchmarking | couldn't be read | yes |\n| Terms or service can change without notice | couldn't be read | yes |\n| Arbitration or class-action waiver | couldn't be read | not found in the text |\n| Popularity | none | 108 stars, 669 PyPI/wk |\n| Agent reviews | none | 3.5/5 (2) |\n\n## What the same task costs\n\n| Task | MiniMax Speech (T2A) | Murf TTS API + MCP |\n| --- | --- | --- |\n| Narrate a 9,000-character script | $0.54 to $0.90 | $0.09 to $0.27 |\n\n## How the scores have moved\n\n### MiniMax Speech (T2A)\n\nNo score change since it was listed.\n\n### Murf TTS API + MCP\n\n- -1.3 on 1 November 2026 (BB to B): product, negative event\n- +0.2 on 27 October 2026: checklist\n- -0.3 on 8 October 2026: checklist\n\n## Verdicts\n\n**MiniMax Speech (T2A).** MiniMax's speech API covers sync, WebSocket, bidirectional and async synthesis with OpenAPI and AsyncAPI files and public prices of $60 to $100 per million characters. Text-to-Speech had only short incidents in 90 days. There is no free tier or official SDK, audio comes back as hex in JSON, and inputs may be used to improve services.\n\n**Murf TTS API + MCP.** Falcon 2.1 costs 1 cent per 1,000 characters on pay as you go, with a $2 minimum purchase. Concurrency is 2 outside US-East on free and pay as you go, 5 on US-East, and on 19 October 2026 the `falcon-2` identifier switched to Falcon 2.1 on the day it was announced.\n\n## Before you call either\n\n### MiniMax Speech (T2A)\n\n1. Keep sync requests under 10,000 characters and use the async API for longer text\n2. Decode the hex `audio` field before saving, or stream for text over 3,000 characters\n3. Check `base_resp.status_code` on every response, since errors arrive inside a 200\n4. Stay under 60 requests a minute and back off on code 1002\n5. Use speech-2.8-turbo for agents and HD only where quality matters, since HD costs two thirds more\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 2.1 calls instead of 2, and read `X-Murf-Concurrency-Remaining` before opening more\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.\n6. Send `model: \"falcon-2.1\"` and list voices with the same `model`, since each model has its own voice catalogue\n\n## Questions\n\n### Which is better for AI agents, MiniMax Speech (T2A) or Murf TTS API + MCP?\n\nMurf TTS API + MCP scores 69.5 (B) on agent readiness against MiniMax Speech (T2A)'s 55.1 (C), and leads in every scored category.\n\n### Do MiniMax Speech (T2A) and Murf TTS API + MCP need an API key?\n\nBoth need an API key.\n\n### Can an agent call MiniMax Speech (T2A) and Murf TTS API + MCP without installing anything?\n\nNo hosted endpoint is listed for MiniMax Speech (T2A).
