Simple Process

How it works

Three steps from request to response with full telemetry and observability.

1. Send

Call Sincere.dev with your prompt or media spec using our SDK or REST API. Simple, consistent interface.

2. Route

Smart router selects the optimal vendor and model based on your policies, costs, and real-time performance.

3. Deliver

Stream results with comprehensive metrics, detailed logs, and distributed traces for complete observability.

Simple, unified API

Use one client for text and media across providers.
