Read only

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 the transcribers that DialNexa can use as fallback speech-to-text providers. Use this endpoint when you are building an agent configuration UI or validating an agent payload before setting stt_fallback_transcriber_id.

When to use this

Agent configuration UIs: populate the Fallback STT selector with eligible transcribers.
Validation scripts: confirm a saved fallback transcriber ID still exists before updating an agent.
Runtime configuration tools: separate primary transcriber choices from fallback-specific choices when your UI exposes both.

For the full transcriber catalog, use List Transcribers.

Example request

curl "https://api.dialnexa.com/v1/transcribers/fallback" \
  -H "Authorization: Bearer YOUR_API_KEY"

Example response

[
  {
    "id": "trs_tr0deepnova3xx",
    "name": "Deepgram Nova 2",
    "provider": "deepgram",
    "model_id": "nova-2",
    "description": null,
    "supported_language_codes": null
  }
]

supported_language_codes: null means the fallback transcriber is not limited to a fixed language-code list in the catalog response.

Use the ID on an agent

After you choose a fallback transcriber, pass its id to Create Agent or Update Agent:

{
  "fallback_stt_enabled": true,
  "stt_fallback_transcriber_id": "trs_tr0deepnova3xx",
  "stt_fallback_wait_ms": 1200
}

Errors

401 Unauthorized is returned when the API key is missing, malformed, or revoked.
403 Forbidden is returned when the API key cannot access the organization.

List Transcribers: fetch the full speech-to-text catalog.
Get Transcriber Details: inspect one transcriber by ID.
Create Agent: configure fallback STT while creating an agent.
Update Agent: change fallback STT on an existing agent.
