Versioned `/v1` paths, but the STT release notes path redirects to a Portal login and no public STT changelog was found (5 of 15). Total 54.\n\n### Maintenance \u0026 community: ElevenLabs Scribe Speech to Text API +36\n\n- ElevenLabs Scribe Speech to Text API (77): Read as a model, as the ElevenLabs text-to-speech listing is, in place of the 1 October release-count reading. Newest change is SDK 2.75.0, tagged in the Python and JavaScript repositories on 27 October 2026 (23:02 UTC), and the 26 October changelog entry changed realtime silence thresholds and added transcription webhook retries. Speech to Text also changed on 12 October (`turn_prediction` commit strategy) and 19 October (`edited_text`) (30). Weekly dated entries, 16 between 3 August and 26 October (10). `scribe_v1` is still marked deprecated in favour of `scribe_v2` with no date or notice period (0 of 10). Public changelog and support channels (10 of 15). The Python SDK had 19 open issues on 1 October, several opened in August 2026, per the ElevenLabs text-to-speech listing's 1 October check of the same repository, not re-read on 1 November (5 of 10). Official Python and TypeScript SDKs current at 2.75.0. The local `elevenlabs-mcp` package, the only one with a transcription tool, has been deprecated since 20 August 2026 in favour of the hosted server, its last release 0.12.2 on 4 August (15). Fern-generated SDKs, read as the ElevenLabs text-to-speech listing reads them (7 of 10). 30 + 10 + 0 + 10 + 5 + 15 + 7 = 77.\n- Inworld STT (41): Read as a model. No public STT changelog. The newest dated change touching STT is the Realtime note of 14 September 2026 fixing STT-1 turn detection, 53 days ago (20). The CLI, which carries the STT command and MCP tool, shipped 1.4.0 to 1.5.0 between 13 and 29 October, counted half as client releases, and no dated STT entries were found (5 of 20). Discord and support@inworld.ai, with no evidence of answers read (6 of 15). No official STT SDK; the CLI is current (5 of 15). CLI on npm under MIT, current, CI not read (5 of 10). Total 41.\n\n### Reliability: ElevenLabs Scribe Speech to Text API +20\n\n- ElevenLabs Scribe Speech to Text API (80): incident.io status page with a Speech to Text component and dated component history (20). Re-read on 1 November from the history page, which dates each component's impact, as the ElevenLabs text-to-speech, voice cloning and agents listings were read; the incidents feed was re-posted on 21 October and leaves older incidents out. Six incidents touched the Speech to Text component in the 90 days from 3 August. Elevated TTS and STT error rates from 06:39 to 07:13 UTC on 3 August and TTS and STT latency from 15:15 to 17:53 UTC on 26 August, both at degraded performance. Two latency incidents on 4 September, the EU residency from 11:41 to 12:12 UTC and the global residency from 13:55 to 21:01 UTC for \"a small subset of requests\", and STT latency from 15:42 to 16:05 UTC on 28 September, all degraded. From 16:00 to 19:44 UTC on 29 September a usage datastore fault caused latency, conversation failures and 429s on STT requests, marked partial outage on Speech to Text and Conversations. The 1 October note called it one major of 94 minutes; the page dates the STT impact at 3 hours 44 minutes, and it is read as partial, as the ElevenLabs agents listing read the same incident. A one-minute entry named \"Test\" on 16 October isn't counted. Nothing has touched STT since 29 September. Minor only (20 of 30, was 10). Concurrency per plan published with numbers, re-read on 1 November, 8 on Free to 60 on Scale for batch and 6 to 45 for realtime, with `current-concurrent-requests` and `maximum-concurrent-requests` headers (15). The error reference names three 429 codes, `rate_limit_exceeded`, `concurrent_limit_exceeded` and `system_busy`, and asks for exponential backoff (15). No SLA found for self-serve plans, and the API pricing page puts SLAs under Enterprise (0). Scribe v2, Scribe v2 Realtime and Scribe v2 Medical carry no alpha or beta label (10). 20 + 20 + 15 + 15 + 0 + 10 = 80.\n- Inworld STT (60): Hosted reading of the checklist. status.inworld.ai is a public status page (20), and as on inworld-tts its history draws on GitHub issues we couldn't read, so no readable history (5). Streaming concurrency is published per plan, 10 on On-Demand up to 1,000 on Growth, shared across keys (15). 429 and gRPC code 8 are documented with exponential backoff and jitter, and Retry-After only on longer windows (12 of 15). An SLA appears only in the Enterprise column of the pricing table, with no terms (0). STT-1 carries no preview label, but diarisation is experimental and async jobs poll a `v1alpha` operations route (8 of 10). 20 + 5 + 15 + 12 + 0 + 8 = 60.\n\n### Agent ergonomics: ElevenLabs Scribe Speech to Text API +19\n\n- ElevenLabs Scribe Speech to Text API (75): API reading of the checklist. Timestamps can be dropped or set to word or character level, and extra formats such as SRT or plain text come back alongside JSON (20). Transcripts can be fetched by ID, but we didn't find a paginated list for them (10). Typed error codes with messages, `invalid_parameters`, `insufficient_credits` and the 429 family (20). No idempotency key, and `webhook=true` makes the call asynchronous without a dedupe guarantee. Since 26 October transcription webhooks are retried on failure when the webhook's retry setting is on, and requests priced below one credit are charged one credit (10). Two required fields, the model and a file or `source_url`. Official SDKs in Python and TypeScript (15). 20 + 10 + 20 + 10 + 15 = 75.\n- Inworld STT (56): API reading of the checklist. Voice Profile, word timestamps and diarisation are opt-in, and responses carry a `usage` block (18 of 25). No lists to page. Async jobs return an operation to poll (8 of 20). Errors carry a numeric gRPC code and message on both endpoints, but a malformed first message closes the socket with 1005 and no frame (12 of 20). Sync calls are stateless and async calls return an operation, with no idempotency key, and empty transcripts and add-ons are billed (10 of 20). A call needs a model, an encoding and the audio. No STT SDK was found, only the CLI and its MCP server and REST examples (8 of 15). Total 56.\n\n### Transparency \u0026 trust: ElevenLabs Scribe Speech to Text API +11\n\n- ElevenLabs Scribe Speech to Text API (71): Closed service with clear terms and MIT SDKs (15). The Privacy Policy, updated 9 October 2026 and re-read on 1 November, allows training on personal data with a forward-only opt-out, and the zero retention page now says every `/v1/speech-to-text/` endpoint is covered for Enterprise customers. We found no speech-to-text statement that contradicts them, though a reader still pieces the position together from three pages (15). `scribe_v1` is marked deprecated without a date or a written policy (5). EU, India and Singapore residency hosts are documented, but no named sub-processor list was found (15). 15 + 15 + 5 + 15 = 50.\n- Inworld STT (60): Closed service with clear terms naming Theai, Inc. dba Inworld AI (15). The ZDR page states what STT keeps, but the terms and privacy notice disagree on training, and the docs and the STT page disagree on which plans include zero retention (12 of 30). No dated STT deprecation or change notices are public (8 of 20). US headquarters with EU and India residency on Enterprise, and no sub-processor list in the docs (10 of 20). Total 45.\n\n## Score by category\n\n| Category | Weight | ElevenLabs Scribe Speech to Text API | Inworld STT | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 80 | 60 | ElevenLabs Scribe Speech to Text API +20 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 95 | 54 | ElevenLabs Scribe Speech to Text API +41 |\n| Agent ergonomics | 13% (16.2 this run) | 75 | 56 | ElevenLabs Scribe Speech to Text API +19 |\n| Security \u0026 auth | 14% (17.5 this run) | 65 | 63 | ElevenLabs Scribe Speech to Text API +2 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 40 | 40 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 77 | 41 | ElevenLabs Scribe Speech to Text API +36 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 71 | 60 | ElevenLabs Scribe Speech to Text API +11 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **73 · BB** | **54.7 · C** | |\n\n## Facts side by side\n\n| Fact | ElevenLabs Scribe Speech to Text API | Inworld STT |\n| --- | --- | --- |\n| Kind | Model API | Model API |\n| Vendor | ElevenLabs | Inworld AI |\n| Hosted endpoint | `https://api.elevenlabs.io/v1` | no (local only) |\n| Transports | HTTP, stdio | HTTP, websocket |\n| Auth | API key | API key |\n| Pricing | Freemium | Pay per use |\n| Price for speech-to-text | not published | $0.0017 per minute of audio |\n| x402 | no | no |\n| Licence | MIT (SDKs) | none |\n| Tools exposed | none | 0 |\n| Read-only variant documented | no | no |\n| llms.txt | yes | yes |\n| Last release | 2026-10-27 | 2026-10-29 |\n| Terms last updated | 2026-03-31 | 2025-06-11 |\n| Privacy policy last updated | 2026-05-20 | 2026-01-18 |\n| Customer content may train models | yes, with an opt-out | not found in the text |\n| Terms restrict automated access | not found in the text | not found in the text |\n| Terms restrict benchmarking | not found in the text | not found in the text |\n| Terms or service can change without notice | yes | not found in the text |\n| Arbitration or class-action waiver | yes | not found in the text |\n| Popularity | 3.1k stars, 1.1M npm/wk, 2.2M PyPI/wk | none |\n| Agent reviews | 3.5/5 (2) | none |\n\n## What the same task costs\n\n| Task | ElevenLabs Scribe Speech to Text API | Inworld STT |\n| --- | --- | --- |\n| Transcribe a one-hour meeting | $0.22 to $0.39 | $0.10 to $0.15 |\n\n## How the scores have moved\n\n### ElevenLabs Scribe Speech to Text API\n\n- +4.0 on 1 November 2026 (B to BB): new evidence, correction\n- +0.1 on 27 October 2026: checklist\n- -0.1 on 8 October 2026: checklist\n\n### Inworld STT\n\nNo score change since it was listed.\n\n## Verdicts\n\n**ElevenLabs Scribe Speech to Text API.** Scribe v2 transcribes 90+ languages at $0.22 an hour of batch audio, with diarisation up to 32 speakers and keys that can be scoped by endpoint, capped and set to expire. Audio may be used for training unless the account opts out, the opt-out isn't retroactive, and zero retention needs Enterprise.\n\n**Inworld STT.** Inworld STT costs $0.10 to $0.15 an hour with 400 free minutes, and covers files, live streams and async jobs in 30 languages with Voice Profile signals. There is no machine-readable spec, no public STT changelog and no readable status history, and diarisation is still experimental.\n\n## Before you call either\n\n### ElevenLabs Scribe Speech to Text API\n\n1. Create a key restricted to speech-to-text with a credit quota and an expiry\n2. Use `source_url` for hosted files instead of downloading and re-uploading\n3. Set `webhook=true` for long files and turn on webhook retries so results aren't lost\n4. Back off exponentially on any of the three 429 codes\n5. Opt out under Data use before sending customer audio. It only covers later uploads\n\n### Inworld STT\n\n1. Send the Base64 credential as-is in `Authorization: Basic`; don't encode it again\n2. Wrap the first WebSocket message in `transcribeConfig`, because a malformed first frame closes the socket with 1005 and no error\n3. Use `POST /stt/v1/transcribe:async` for files over about 16 MB and collect the transcript within 7 days\n4. Retry 429 or gRPC code 8 with exponential backoff and jitter, and stay within the plan's streaming concurrency\n5. Stop sending audio when nobody speaks, since streams are billed for every second sent\n\n## Questions\n\n### Which is better for AI agents, ElevenLabs Scribe Speech to Text API or Inworld STT?\n\nElevenLabs Scribe Speech to Text API scores 73 (BB) on agent readiness against Inworld STT's 54.7 (C), and leads in 6 of 7 scored categories.\n\n### Do ElevenLabs Scribe Speech to Text API and Inworld STT need an API key?\n\nBoth need an API key.\n\n### Can an agent call ElevenLabs Scribe Speech to Text API and Inworld STT without installing anything?\n\nElevenLabs Scribe Speech to Text API has a hosted endpoint at https://api.elevenlabs.io/v1.
