Natera’s intelligent appointment scheduling with Amazon Bedrock AgentCore
Natera deployed a voice agent handling real appointment bookings with 100% tool accuracy and sub-7-second latency. Here's how they solved the dual-WebSocket and latency-masking problems.

Why it matters
Production agent case study with engineering depth: real deployment metrics, architectural patterns (event-driven latency masking, progressive-trust auth), and tool-calling reliability at scale. Practitioners building voice agents can extract specific patterns; enthusiasts see proof that agent infrastructure is hardening.
