Resemble AI Voice Cloning API 0

No x402, MPP or L402 (0). The per-second speech and per-slot prices were read on 30 September from app.resemble.ai/billing/api/v1/plans, a billing data endpoint this run doesn't read, so that reading is struck, and the pricing pages can't be re-read under the terms, so no per-unit price for the API stands today (0). The changelog's $2 for later clones is the Flex web app's, not the API's. No API cloning below Business per the 2 October check, and the free first clone in the Flex web app captures a card for later clones (0). Signup is a human browser flow (0).

Smallest.ai Instant Voice Clone 20

No x402, MPP or L402 (0). Per-character TTS prices are public, about $0.175 per 10,000 characters on Lightning v3.1, but no price per clone is published and the models pricing table marks voice cloning No on pay as you go, against the docs (10). The agents pricing page states $10 in free credits, and whether a card is needed wasn't established (10 of 20). A person signs up in a browser and creates the key in the dashboard (0). 0+10+10+0 = 20.

The API reference pages are generated with typed fields, enums and error schemas, but no OpenAPI file was found linked from the docs or llms.txt (5 of 25). llms.txt and a Markdown copy of every page (10). The guide says when to use the Pro pool, how to check modelIds before synthesis and why a mismatched clone returns empty audio, while the reference still names the retiring default (14 of 20). model and language are enums validated by the server, with required displayName and file, a 5 MB limit and MIME types listed, and tags as a comma-separated string (12 of 15). Examples in curl, Python and Node.js and a table of seven error cases with causes (14 of 15). Paths under /v1, a deprecation page with dated statuses and a models changelog with entries on 21, 24, 26, 28 and 29 October 2026 (15). 5+10+14+12+14+15 = 70.

Resemble AI Voice Cloning API 54

Graded for voice cloning, with consent and misuse controls in place of the read-only line and training and retention of voice data in place of the prompt-injection line, since the API returns audio and IDs rather than third-party text. Plain Bearer API keys, no scopes found (20 of 30). The terms say Resemble may require verbal consent from the person cloned. The API reference has no consent field, though the Node SDK still sends an optional consent value added in 2023. Watermarking and deepfake detection sit in the same account (4 of 20). The privacy policy of 14 August 2026 says customer voice data isn't used to train general-purpose models or for research, recordings and voice models are kept while the account is active plus a 30-day grace period, and synthesis text and audio aren't kept after delivery (12 of 15). Clone slots and usage readable through the Billing API, no per-call log found (8 of 15). The Secureframe trust centre lists ISO 27001:2022 as certified, an annual third-party penetration test, and SOC 2 Type 2 still in its observation period on 2 October, two days after the date it gave for the report. No security.txt, disclosure policy or bug bounty found (10 of 20). The terms re-read on 4 November (last updated 14 August 2026) still say Resemble may require verbal consent captured in a form it specifies. OSV lists no records for @resemble/node or resemble. The rest per the 2 October check, not re-read on 4 November (Resemble's terms bar automated means).

Smallest.ai Instant Voice Clone 48

Graded for voice cloning as the other listings in this category, with consent and misuse controls in place of the read-only line and training and retention of voice data in place of the prompt-injection line. Plain bearer keys, shown once, revocable, with rotation guidance and no scopes. Short-lived access tokens are refused on the cloning endpoint (20 of 30). No consent or verification field. The Terms let Smallest demand proof that the speaker authorised a clone and remove voices without it, and the prohibited use policy bars unauthorised impersonation. No watermark found (6 of 20). The Terms say Smallest won't use User Content or Input to train its services. Zero retention and retention windows are Enterprise options, and no retention period for samples is published (9 of 15). A usage dashboard, with no audit log found (5 of 15). A valid security.txt naming security@smallest.ai and a HIPAA business associate agreement page. The trust centre didn't answer through our proxy, so no certification was confirmed first-hand, and no bug bounty was found (8 of 20). 20+6+9+5+8 = 48.
