Cekura AI natively integrates with Vapi to bring end-to-end reliability and observability to voice AI agents
About Vapi
Vapi is the most configurable API for building, deploying, and scaling voice AI agents. Developer-first and API-native, Vapi covers STT, LLM, TTS, tools, assistants, squads, dynamic variables, and every channel that matters — inbound and outbound telephony, WebRTC, SIP, SMS, and WhatsApp. With 300M+ calls processed and 2.5M+ assistants launched, Vapi is one of the fastest paths from idea to a live voice agent in production.
About Cekura AI
Cekura is the automated QA and observability platform for conversational AI. Teams use Cekura to catch regressions before they ship and to continuously monitor real traffic once agents are live — an AI-native testing loop modeled on the unit-test-to-observability pipelines engineers already trust, tailored to voice.
How Vapi × Cekura Customers Benefit from the Native Integration
Cekura is natively integrated with Vapi. Using your Vapi API keys, Cekura pulls assistant configuration, tools, dynamic variables, and call metadata straight from Vapi, and drives tests through Vapi's own infrastructure — so AI-generated scenarios, automated evaluation, and production monitoring run end-to-end with no glue code.
Scenario Generation with Evaluation Metrics — Cekura's AI generates scenarios, metrics, personas, and scenario-aligned mock tool return values, all autofetched from your Vapi config.
- Vapi WebRTC Simulations — Drop in your Vapi public key and tests run over a direct WebRTC connection to your assistant. No phone number, no telephony cost — ideal for CI.
- Automated Outbound Calling — Cekura places real phone calls between your Vapi agent and Cekura test agents, running the whole suite end-to-end over PSTN.
- Autofetch of Production Calls — Turn it on and Cekura continuously ingests live Vapi calls, auto-scoring every one against your evaluators.
- Detailed Tool Call Information — Every run surfaces the full tool-call trace — what fired, with what arguments, in what order — alongside a pluggable library of evaluators, transcription accuracy, latencies, and the raw Vapi JSON.
- Metadata Access — Vapi call metadata surfaces alongside transcripts and scores — slice by customer or cohort, power context-aware evaluators, and one-click back to the exact Vapi call ID.
- Channel Coverage Across Voice, Telephony, SIP, and Chat — Configure the Vapi agent once; run the same suite across voice (WebRTC), telephony (PSTN), SIP, and chat (SMS/WhatsApp).
