Provider evidence profile · attributable, not endorsed
Cartesia
A canonical, fixture-validated provider adapter for static Sonic model discovery, account-scoped voice discovery, and standardized PCM Text to Speech.

Evidence boundary
These fields report repository and documentation state. They are not a provider quality ranking or production-readiness claim.

- Credential readiness
- Unconfigured
- Readiness explanation
- A provider-neutral adapter is fixture-validated; live invocation remains disabled until every policy and cost gate is satisfied.
Inspect capability evidenceHuman-readable capability families first; exact contract evidence remains available separately.
Capabilities in ONE
Provider-documented support and installed integration remain attributable and separate.

Limitations
- Canonical exact-operation authorization is required before credential access or provider transport; operational policy remains server-authoritative.
- Static model metadata is documentation-backed; voice discovery is account-scoped and requires a configured server credential.
- LIVE CARTESIA VERIFICATION: NOT PERFORMED. Fixtures do not establish account entitlement, live availability, latency, quality, pricing, or production suitability.
- Only the current API contract's sonic-3.5 and sonic-3 identifiers are accepted. Mutable aliases and dated snapshots are intentionally excluded.
- Voice cloning, WebSocket contexts, provider-native optimization controls, and pricing estimates are not implemented.
