Resolve an agent's speech-to-text failover chain
Resolve the ordered speech-to-text provider failover chain for a voice agent: an optional per-language override (exact BCP-47 tag, then base-language match) first, then the agent-level fallback chain, de-duplicated and restricted to the providers the voice gateway has wired. Use it (optionally with ?language=en-US) to determine which speech-to-text providers a call should try, in order; an empty chain means the gateway falls back to its platform default order. Internal service-to-service endpoint used by the voice gateway at call setup and on mid-call language switches.

Headers
Sandbox opt-in for Clerk-session-authenticated requests. Set to true to route the call through the test-mode pipeline: no real provider delivery, no credits deducted, response meta.test_mode: true. Ignored for live API keys (dv_live_sk_*) — server-to-server clients must use a test-prefixed key (dv_test_sk_*) to exercise sandbox. Test-prefixed keys unconditionally enable sandbox regardless of this header.
