redact-secret · Report
API key (sk_)
sk_ + 48 lowercase hex, with an optional provider-code-evidenced _residency_<region> suffix, sent in the xi-api-key header.
Registry detector elevenlabs-api-key since redact-secret#865 (registry pinned at cfe2aec); graduated from a Beta.10 arrival family (#384, research #788), contract in benchmarks/lib/beta8/384c.ts. T1 by maintainer ruling of 2026-09-27 (redact-secret#788) on ElevenLabs SDK code for the sk_ prefix and the _residency_[a-z0-9]+ suffix grammar; the 48-lowercase-hex body stays T2 and no fixture asserts it. sk_ is shared with Stripe (sk_live_, sk_test_, sk_org_) and Pollinations.

Benchmark dossier notes
From the provider dossier, as written. The evidence level above says how well the format is backed; a fact the dossier does not record is not shown.
- Shape
sk_followed by 48 lowercase hexadecimal characters (51 in all), with an optional_residency_<region>suffix matching_residency_[a-z0-9]+(regions seen:in,eu). The suffix belongs to the key, so a residency key is redacted whole. Body length and alphabet are stated by no provider source.- Basis
- T1 by maintainer ruling of 2026-09-27, on provider SDK code (the
huggingface:api-tokenprecedent): a docstringapi_key="sk_..."inspeech_engine/server.py, and_RESIDENCY_KEY_SUFFIXinresource.pyand the JSSpeechEngineResource.ts. The docs pages state neither prefix nor length. The body is T2: trufflehog v2, betterleaks (Kingfisher aliases it) and about 35 code-search fragments, all 48 lowercase hex where fully formed. - Issuance
- not attempted. The #788 checklist covers user and service-account keys, an isolated-environment key and its suffix, the displayed
hint, and whether an old account still holds a 32-hex key. - Contract in core
- detector-families.md; the spec row records the T1 ruling and the T2 body. #866 covers the single-line SDK-argument form generically.

Benchmark dossier questions
Things the sources do not settle. They are listed so nobody reads them as settled.
- Open caveat
- T1 covers the sk_ prefix and _residency_ suffix (SDK code, by ruling); the 48-lowercase-hex body is T2 with no provider statement. The legacy 32-hex form is unresearched; needs issued keys (checklist in #788).
Looks like it, but isn't
Values the dossier records as resembling this credential without being one.
- Collisions
sk_is shared with Stripe (sk_live_,sk_test_,sk_org_) and with a planned Pollinationssk_plus 32 characters key, so the prefix alone cannot attribute a key. The response fieldskey_id,hintandhashed_xi_api_keyare non-secret; so are voice ids.
Scanner rules for this family
Mapped by hand (reviewed 2026-09-30) from each scanner's pinned rule file, never from what a scanner found on the fixtures.
| Scanner | Rule | What the rule matches |
|---|---|---|
| trufflehog · rules 3.97.4 | elevenlabs/v2 | sk_ + 48 hex |
No rule maps to this family in flare-redact, gitleaks, openredaction.
