Recommended. This endpoint is part of the public /v1 API reference and is the supported path for new integrations. See the migration guide for versioning guidance.
Returns every language DialNexa supports for agent prompts, speech-to-text transcription, and text-to-speech synthesis. Each entry includes the language’s stable id, its BCP-47 code (for example en-IN, hi-IN, en-US), the human-readable display name, and the set of voices available in that language. Use this endpoint as the canonical source of truth for what the platform currently supports, language coverage evolves as providers add new models.

When to use this

  • Agent build UIs: populate the language dropdown when creating or editing an agent.
  • Validation pipelines: confirm a language is still supported before publishing an agent change.
  • Multi-region rollouts: discover which languages have voice coverage in a given region.
  • Internationalization audits: verify your DialNexa deployment supports every language your customer base speaks.
For a single record, use Get Language Details.

Errors

  • 401 Unauthorized is returned when the API key is missing or revoked.
