Unified OpenAI-compatible API fronting 400+ LLMs across 70+ providers, with automatic fallback, provider preferences, BYOK, and pay-per-token billing.
OpenRouter (openrouter.ai) is a routing layer that gives you a single OpenAI-compatible endpoint (openrouter.ai/api/v1/chat/completions) fronting 400+ active language models from 70+ providers — Anthropic, OpenAI, Google, Meta, Mistral, DeepSeek, Zhipu, Qwen, Cohere, xAI, Together, Fireworks, Groq, Amazon Bedrock, Google Vertex, and dozens of smaller labs. Instead of maintaining half a dozen provider SDKs, keys, and billing relationships, you send requests with a model slug like anthropic/claude-opus-4-7 or openai/gpt-5 and OpenRouter routes to the right provider, streams the response back, and bills your OpenRouter credit balance. Provider routing preferences let you optimize for price, latency, throughput, or privacy (Zero Data Retention), and if one provider throttles or errors, OpenRouter automatically falls back to an equivalent endpoint so your app keeps running. BYOK (Bring Your Own Key) lets you plug in your own Anthropic, OpenAI, or Bedrock keys and pay only a 5% fee on what those requests would have cost on OpenRouter — waived for the first 1M BYOK requests per month. Extras include per-app spending guardrails with budget caps, request analytics and logs, model/price/latency leaderboards, and a rotating catalog of free community-hosted models with rate limits. OpenRouter has become the default gateway for many agent frameworks (LangChain, LlamaIndex, Continue.dev, Aider), MCP hosts, and no-code tools. Compared to LiteLLM (self-hosted proxy you run yourself) or Portkey (enterprise gateway with heavier governance features), OpenRouter is the SaaS convenience option — you trade an extra network hop and a single-vendor dependency for zero infra and one bill.
