Thank you!" } } }' ``` ## Important Notes 1. **Required Fields**: Only `agent_name` and `prompt` are required. The `voice` object is optional — include `voice` (with `provider` and `voice_id`) when you want to configure TTS for the agent. All other fields are optional. 2. **Voice IDs**: Get available voice IDs from the [List Voices API](/api-reference/voice-ai/list-voices). 3. **Webhooks**: If you provide a `session_data_webhook`, ensure your endpoint can handle POST requests with session data. 4. **Timezones**: Use standard timezone strings (e.g., "America/New\_York", "Europe/London", "Asia/Tokyo"). 5. **Language Names**: Use full language names (e.g., `english`, `hindi`, `spanish`) or region-specific variants (e.g., `english_us`, `english_uk`) as shown in the Speech-to-Text section above. 6. **Model Compatibility**: Ensure the voice model is compatible with your chosen provider. For example, `eleven_turbo_v2_5` only works with ElevenLabs. 7. **Rate Limits**: API calls are subject to rate limiting based on your plan. See [pricing documentation](/pricing/call-pricing) for details. 8. **Testing**: After creating an agent, test it thoroughly before using in production. Use the [Make Call API](/api-reference/voice-ai/make-call) to test your agent. 9. Attaching phone numbers is necessary to place calls via agents ## Related Endpoints * [List Voices](/api-reference/voice-ai/list-voices) - Get available voice IDs * [Update Voice Agent](/api-reference/voice-ai/update-voice-agent) - Modify agent settings * [List Voice Agents](/api-reference/voice-ai/list-voice-agents) - View all agents * [Delete Voice Agent](/api-reference/voice-ai/delete-voice-agent) - Remove an agent * [Make Call](/api-reference/voice-ai/make-call) - Test your agent with a call ## OpenAPI ````yaml api-reference/openapi.json POST /create-agent openapi: 3.1.0 info: title: >- UnleashX - Build human like conversations | Voice Agents | Automations | AI Workforce version: 1.0.0 description: UnleashX - Your home for human like conversations servers: - url: https://www.tryunleashx.com/api/v1/global/ security: - bearerAuth: [] paths: /create-agent: post: tags: - Voice AI summary: Create voice agent parameters: - name: token in: header required: true description: API token for authentication schema: type: string requestBody: required: true content: application/json: schema: type: object properties: agent_id: type: integer agent_name: type: string description: type: string prompt: type: string timezone: type: string greeting: type: string session_data_webhook: type: string voice: type: object properties: provider: type: string enum: - elevenlabs - openai - deepgram - sarvam voice_id: type: string model: type: string settings: type: object speech_to_text: type: object properties: provider: type: string model: type: string language: type: string enum: - english - hindi - multi - albanian - arabic - armenian - azerbaijani - belarusian - bengali - bosnian - bulgarian - catalan - chinese - croatian - czech - danish - dutch - english_australia - english_india - english_new_zealand - english_uk - english_us - english_spanish - estonian - finnish - french - galician - georgian - german - german_switzerland - greek - gujarati - haitian_creole - hausa - hebrew - afrikaans - hungarian - icelandic - indonesian - italian - japanese - javanese - kannada - kazakh - khmer - korean - latvian - lithuanian - macedonian - malay - malayalam - maori - marathi - nepali - norwegian - persian - polish - portuguese - portuguese_brazil - punjabi - romanian - russian - serbian - shona - slovak - slovenian - somali - spanish - spanish_latin_america - sundanese - swahili - swedish - tagalog - tamil - tajik - telugu - thai - tswana - turkish - ukrainian - urdu - vietnamese - welsh llm: type: object properties: llm: type: string model: type: string configurations: type: object responses: '201': description: Created security: [] components: securitySchemes: bearerAuth: type: http scheme: bearer ````
