# Opper API

Opper is a **gateway** in front of LLM providers plus a **control plane** for the things you build on top. The gateway is one connection to 200+ models across all major providers (OpenAI, Anthropic, Google, Mistral, …). The control plane covers five capabilities:

- **Route** — call any supported model through one key, no provider-specific SDKs or credentials.
- **Observe** — every call yields a trace with input, output, latency, cost, and model used; attach metrics and evaluations to track quality over time.
