About OpenRouter

OpenRouter gives you one API endpoint to call models from OpenAI, Anthropic, Google, Meta, Mistral, and 60+ other providers. Instead of managing separate API keys and billing accounts for each, you fund an OpenRouter balance and it handles routing. The API is compatible with OpenAI's format, so most existing code works without modification. The platform passes through provider pricing without markup — you pay what the provider charges, plus a small fee on credit purchases. It also does automatic failover: if a provider is down or rate-limits you, OpenRouter tries the next best option automatically. Founded in 2023 by Alex Atallah (OpenSea co-founder), OpenRouter now serves 4.2M+ users across 250k+ apps, processing 30+ trillion tokens per month. Enterprise features include SSO, team spend controls, and EU data residency. It's particularly useful for developers who want to compare multiple models without rewriting their integration each time.
