ElevenLabs API keys

• Provider documentation SpeechEngineServer docstring api_key="sk_..." and the _residency_ suffix regex in elevenlabs-python and elevenlabs-js · observed 2026-09-26 · ElevenLabs' own SDK source shows keys written sk_... and parses a data-residency suffix with _residency_[a-z0-9]+$ (elevenlabs-python speech_engine/resource.py, elevenlabs-js SpeechEngineResource.ts). No documentation page states the prefix, a length or an alphabet. Provider code is not documentation; T1 on it is the maintainer ruling of 2026-09-27 (redact-secret#788, huggingface:api-token precedent), scoped to the sk_ prefix and the _residency_ suffix grammar. The 48-hex body stays T2

Arrival evidence (#384, product redact-secret#865; research #788), T1 by maintainer ruling of 2026-09-27 on provider SDK code for the sk_ prefix and the _residency_ suffix grammar, graduated to a registry detector at cfe2aec. The body claims below stay T2 and no fixture asserts them: the sk_ prefix and the _residency_<region> suffix rest on ElevenLabs' own SDK source, the 48-lowercase-hex body on trufflehog's v2 detector, betterleaks and about 35 code-search fragments (each fully formed body was 48 hex characters), and no ElevenLabs page states any of it. Both tool rules are keyword-gated on elevenlabs, xi-api-key or xi_api_key; the contract claims the bare shape, as the product issue does, on the strength of the sk_ prefix, so nothing here relies on the gate. sk_ is shared with Stripe (sk_live_, sk_test_, sk_org_) and, by plan, Pollinations (sk_ + 32 characters): the Stripe shape is a prefix twin and a bare sk_ prefix cannot attribute a value. A legacy bare 32-hex form has trufflehog v1 evidence only and stays unasserted either way. Uppercase hex is disputed between the tools (betterleaks matches case-insensitively, trufflehog v2 does not), so no fixture asserts silence on it.
