The docs point to status.mistral.ai, which our sibling Mistral listings read on 1 and 2 October 2026 as a Rootly page with component uptime bars (20). On 8 October the page answered curl and WebFetch with a Cloudflare check and HTTP 403, so the 90-day record for audio was not read (5, unread and not a finding against the vendor). The limits page names audio seconds a minute and audio seconds a month as the audio limits, with the numbers shown only in the Admin Panel (3 of 15). The error glossary tells callers to back off exponentially on 429, 500, 502, 503 and 504 and to read the `Retry-After` header, and the official SDKs retry with backoff. Transcription is a stateless call (15). No SLA found (0). The model cards mark Voxtral Mini Transcribe 2 and Voxtral Mini Transcribe Realtime as GA (10).\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 85: Model reading. The public OpenAPI document covers `/v1/audio/transcriptions`, its SSE streaming form and `/v1/client/sessions`. The realtime WebSocket messages are described by SDK types and guide examples, not by the document (22 of 25). llms.txt with Markdown twins of the speech-to-text, offline, realtime and client authentication pages (10). The guides say which model each endpoint runs, that `timestamp_granularities` and `language` cannot be combined and that realtime cannot diarise, and carry an OpenAI SDK compatibility table. In the OpenAPI document `diarize`, `context_bias` and `temperature` have no description (14 of 20). `timestamp_granularities` is an enum of `segment` and `word`, `language` is a two-letter pattern and `context_bias` items have a pattern, while `model` is a free string (12 of 15). curl, Python and TypeScript examples on each guide and a shared error glossary. The OpenAPI response example still names `voxtral-mini-2507` (12 of 15). Dated model identifiers and a dated changelog (15).\n- Agent ergonomics 77: API reading, as for the other speech-to-text listings. Segments, word timestamps and speaker labels are returned only when asked for, and the default response is the text, the language and usage. No subtitle or plain-text output format was found (18 of 25). There is no transcript store to page through. Volume goes through the batch API, which accepts `/v1/audio/transcriptions` (12 of 20). Errors return `type`, `param` and `code` with a fix per status in the glossary (17 of 20). The call is stateless and safe to retry, the SDKs retry with backoff, and no idempotency key exists or is needed (15 of 20). `model` is the only required field beside the audio source, and there are official Python and TypeScript SDKs plus OpenAI SDK compatibility for the batch endpoint (15).\n- Security \u0026 auth 70: Model reading, scored like the other Mistral listings. Keys are bound to one workspace, can carry an expiry date and a connector scope, and organisations can enforce a maximum key lifetime. Browser clients get `rt_` tokens from `POST /v1/client/sessions` that last about 900 seconds, work for one model and travel in `Sec-WebSocket-Protocol`. A key cannot be limited to transcription (26 of 30). The commercial terms effective 25 September 2026 say Mistral will not train on customer data unless the customer opted in, or did not opt out where a product defaults to opt-in, without naming the API's default. The privacy and data controls page the docs link to returned 404 (10 of 20). Input and output are kept 30 rolling days for abuse monitoring, and `/v1/audio/transcriptions` is on the zero data retention list for paid plans, on request and subject to approval (12 of 15). Audit logs cover API key actions on Enterprise plans only (10 of 15). security.txt is valid until 5 May 2027 and names a HackerOne submission form, and the docs publish three security advisories for 2026. Certifications sit in a trust centre drawn by script that we could not read (12 of 20).\n- Payments \u0026 pricing 40: No x402, MPP or L402 (0). $0.003 a minute for Voxtral Mini Transcribe 2 and $0.006 a minute for Voxtral Realtime on public pages (20). Free mode gives API access with no card, within limits shown in the console (20). A person signs up in a browser (0).\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 66: Model reading. The last dated change to transcription is the 4 February 2026 release of both models with diarisation and context biasing, eight months ago. The SDKs that carry the realtime client were released on 6 October 2026 (Python 3.1.0), so we give 10 of 30, a departure from the strict reading of 0. The lifecycle policy promises six months' notice for GA models (12 of 12). No transcription model was retired in the last 90 days of the changelog (8 of 8). Five dated platform changelog entries between 16 July and 6 October, none about audio (8 of 15). The eight newest open issues on client-python have zero or one comment (5 of 10). Official `mistralai` 3.1.0 on PyPI and `@mistralai/mistralai` 2.7.0 on npm (15). Both are generated from the OpenAPI document, with test, lint and example workflows in the repository (8 of 10).\n- Transparency \u0026 trust 82: The hosted service is closed under commercial terms. The Realtime weights are published on Hugging Face under Apache-2.0 and the SDKs are Apache-2.0, while Voxtral Mini Transcribe 2 has no public weights (20 of 30). The privacy policy effective 3 September 2026 (30 rolling days), the zero data retention page and the terms agree on retention, and the terms leave the API's training default unnamed (20 of 30). A model lifecycle page with notice periods per stage (20). Opt-in EU and US regional endpoints are documented, the global endpoint commits to no location, and the provider list is in a trust centre we could not read (13 of 20).\n\nFix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (18 items): https://www.anchorterminal.com/fixes/mistral-voxtral-transcribe.md (JSON https://www.anchorterminal.com/fixes/mistral-voxtral-transcribe.json)\n\n### What we couldn't check\n\n- unchecked: status.mistral.ai answered every request with a Cloudflare check (HTTP 403) on 8 October 2026, so the audio component's uptime and the 90-day incident record were not read\n- unchecked: trust.mistral.ai is drawn by script, so certifications and the provider list were not read\n- unchecked: the privacy and data controls page linked from the zero data retention page returned 404, so the API's training default was not established\n- unchecked: whether Free mode includes transcription minutes and whether sign-up needs a phone number. The quickstart says no card is needed\n- The pricing table shows $0.0003 a minute in a second column for Voxtral Mini Transcribe 2 without a label we could tie to batch or cached use, so it is not listed as a price\n- Whether zero data retention covers the realtime WebSocket at `/v1/audio/transcriptions/realtime`. The list names `/v1/audio/transcriptions` only\n- The transcription curl examples send the key in an `x-api-key` header, while the error glossary gives `Authorization: Bearer`\n- The other Mistral listings took no deduction for advisory MAI-2026-002. This one takes 3 because the realtime client is only reachable through the SDK\n\n### Sources\n\n- speech-to-text overview: \u003chttps://docs.mistral.ai/studio/audio/speech_to_text\u003e (seen 2026-10-08)\n- offline transcription guide: \u003chttps://docs.mistral.ai/studio/audio/speech_to_text/offline_transcription\u003e (seen 2026-10-08)\n- realtime transcription guide: \u003chttps://docs.mistral.ai/studio/audio/speech_to_text/realtime_transcription\u003e (seen 2026-10-08)\n- realtime client authentication: \u003chttps://docs.mistral.ai/studio/audio/speech_to_text/realtime_transcription/client_auth\u003e (seen 2026-10-08)\n- OpenAPI document: \u003chttps://docs.mistral.ai/openapi.yaml\u003e (seen 2026-10-08)\n- Voxtral Mini Transcribe 2 model card and price: \u003chttps://docs.mistral.ai/models/voxtral-mini-transcribe-26-02\u003e (seen 2026-10-08)\n- Voxtral Mini Transcribe Realtime model card and price: \u003chttps://docs.mistral.ai/models/voxtral-mini-transcribe-realtime-26-02\u003e (seen 2026-10-08)\n- API pricing: \u003chttps://mistral.ai/pricing/api/\u003e (seen 2026-10-08)\n- changelog: \u003chttps://docs.mistral.ai/resources/changelogs\u003e (seen 2026-10-08)\n- model lifecycle policy: \u003chttps://docs.mistral.ai/inference/model-lifecycle\u003e (seen 2026-10-08)\n- error glossary: \u003chttps://docs.mistral.ai/resources/error-glossary\u003e (seen 2026-10-08)\n- usage and limits: \u003chttps://docs.mistral.ai/admin/billing-usage/usage-limits\u003e (seen 2026-10-08)\n- API keys: \u003chttps://docs.mistral.ai/admin/identity-access/api-keys\u003e (seen 2026-10-08)\n- zero data retention: \u003chttps://docs.mistral.ai/admin/monitor-comply/zero-data-retention\u003e (seen 2026-10-08)\n- audit logs: \u003chttps://docs.mistral.ai/admin/monitor-comply/audit-logs/overview\u003e (seen 2026-10-08)\n- security advisory MAI-2026-002: \u003chttps://docs.mistral.ai/resources/security-advisories/MAI-2026-002\u003e (seen 2026-10-08)\n- Studio MCP server: \u003chttps://docs.mistral.ai/resources/mcp\u003e (seen 2026-10-08)\n- commercial terms of service: \u003chttps://legal.mistral.ai/terms/commercial-terms-of-service\u003e (seen 2026-10-08)\n- privacy policy: \u003chttps://legal.mistral.ai/terms/privacy-policy\u003e (seen 2026-10-08)\n- security.txt: \u003chttps://mistral.ai/.well-known/security.txt\u003e (seen 2026-10-08)\n- Python SDK releases: \u003chttps://pypi.org/pypi/mistralai/json\u003e (seen 2026-10-08)\n- Python SDK repository: \u003chttps://github.com/mistralai/client-python\u003e (seen 2026-10-08)\n- Realtime open weights: \u003chttps://huggingface.co/mistralai/Voxtral-Mini-4B-Realtime-2602\u003e (seen 2026-10-08)\n\n## Who's behind it (provenance 91/100, checked 2026-10-08)\n\n| Check | Finding | Points |\n| --- | --- | --- |\n| Legal entity named | Mistral AI (RCS Paris 952 418 325) | 20/20 |\n| Domain age | mistral.ai, registered 2019-05-15 (7 years) | 11/15 |\n| Endpoint on the vendor's domain | api.mistral.ai | 15/15 |\n| Terms of service | read, states 6 of the 7 things a reader expects, and has 2 clauses that cost points | 5.1/10 |\n| Privacy policy | read, states 8 of the 8 things a reader expects | 10/10 |\n| Status page | status.mistral.ai | 10/10 |\n| Changelog | published | 10/10 |\n| security.txt | valid | 10/10 |\n\n### Terms and privacy, as read\n\nA reading by a fixed set of rules, each answered with the vendor's own sentence.

Send `model=voxtral-mini-latest` and one of `file`, `file_url` or `file_id` as multipart form fields to `/v1/audio/transcriptions`\n2. Leave `language` out when you ask for `timestamp_granularities`, the docs say the two are not compatible\n3. Use the batch endpoint for diarisation. `voxtral-mini-transcribe-realtime-2602` does not accept `diarize`\n4. Pin `voxtral-mini-2602` if output must not change, since `-latest` aliases can move\n5. Mint browser tokens with `POST /v1/client/sessions` close to connection time and pass them in `Sec-WebSocket-Protocol`, never the API key\n\n## Connect\n\nInstall:\n\n```bash\npip install mistralai # realtime: pip install \"mistralai[realtime]\" # or: npm i @mistralai/mistralai\n```\n\nFirst request:\n\n```bash\ncurl --location 'https://api.mistral.ai/v1/audio/transcriptions' \\\n --header \"x-api-key: $MISTRAL_API_KEY\" \\\n --form 'file_url=\"https://docs.mistral.ai/audio/obama.mp3\"' \\\n --form 'model=\"voxtral-mini-latest\"'\n```\n\n## Similar tools\n\nRanked by shared capabilities, then score.
