How boldrouter works

Developers point their OpenAI SDK client to the boldrouter base URL with a single API key, specify a catalog id or auto-router id, and requests are normalized, routed, and streamed back.

Frequently asked questions

What is boldrouter?

boldrouter is an OpenAI-compatible API gateway that routes requests to major LLM providers through a single endpoint and unified bill.

How does compatibility with OpenAI work?

The gateway implements OpenAI endpoints so any OpenAI SDK works by swapping the base URL and API key without changing application code.

How does failover and routing work?

boldrouter picks providers by price, latency, or uptime and automatically fails over using a health-aware circuit breaker if a provider errors or hits rate limits.

Does boldrouter support bringing your own API keys?

Yes. Developers can use their own provider keys (BYOK), where providers bill directly for tokens and boldrouter charges a 5.5% usage fee.

How does prompt anonymization work?

Opt-in prompt anonymization detects PII like emails, names, and phone numbers, replaces them with opaque placeholders before sending, and can restore values in responses.
