OpenRouter
Unified API to 400+ LLMs from 70+ providers through one OpenAI-compatible endpoint, with automatic failover and pass-through token pricing
OpenRouter is a unified API that routes requests to 400+ LLMs from 70+ providers through one OpenAI-compatible endpoint. Token usage passes through at each provider's posted rate with no markup; OpenRouter instead charges a 5.5% fee on credit purchases (5% for crypto). A free tier covers 25+ models at 50 requests/day. Best for developers who want one integration plus automatic failover across models.

What is OpenRouter?
OpenRouter is a single API gateway that sits in front of hundreds of large language models. Instead of integrating OpenAI, Anthropic, Google, Meta, DeepSeek, and dozens of other providers separately, you point one OpenAI-compatible endpoint at OpenRouter and choose a model by name. It routes the request to a provider that hosts that model, and if the provider is down or rate-limited, it automatically falls back to another — so your app keeps working through individual outages.
The pricing model is deliberately simple: token usage is passed through at each provider’s posted rate with no markup. OpenRouter makes money on a platform fee charged when you buy credits — 5.5% on card purchases (with an $0.80 minimum) or a flat 5% for crypto. A free tier exposes 25+ models at 50 requests per day with no credit card, and adding $10 or more in credits lifts that to 1000 requests per day. Bring Your Own Key routing is free for the first million requests a month, then 5% of the equivalent model cost.
Who is it for?
OpenRouter is built for developers and teams who want model flexibility without rebuilding their integration every time a better or cheaper model appears. It is an API-first product, so the value is in code, not a consumer chat window.
- App and agent developers who want to swap models — or route by price and latency — behind one stable, OpenAI-compatible interface.
- Teams that need reliability, using automatic provider failover so a single vendor outage does not take their product down.
- Cost-conscious builders who route each request to the cheapest capable provider and centralize spend tracking under one credit balance.
- Prototypers testing many models quickly, including the free model pool, before committing to one for production.

- 04 Prototyping cheaply across many models, including 25+ free models
- 05 Centralizing billing and spend tracking for multi-model usage under one account
Pros and cons
| Pros | Cons |
|---|---|
| One integration unlocks 400+ models from 70+ providers via an OpenAI-compatible SDK | The 5.5% credit fee has a $0.80 minimum, so small top-ups pay an effective 10-20% rate |
| No markup on token pricing — you pay the same per-token rates as going direct | Free models are heavily rate-limited (50 requests/day, 20/min) and unsuitable for production |
| Built-in automatic failover improves uptime versus calling a single provider | BYOK is not free at scale — a 5% fee applies after the first 1M requests/month |
| Generous free tier (25+ free models, no credit card) for testing and light use | Adds a routing layer that can introduce extra latency and a dependency on OpenRouter's uptime |
| Only successful completions are billed; failed and fallback attempts are free | No flat subscription — costs are purely usage-based and can be hard to predict |

Frequently asked questions
What is OpenRouter?
OpenRouter is a unified API and marketplace that routes requests to 400+ large language models from 70+ providers (OpenAI, Anthropic, Google, Meta, DeepSeek and more) through a single OpenAI-compatible endpoint, with automatic failover and pass-through token pricing.
How much does OpenRouter cost?
OpenRouter is usage-based. You buy credits and pay per token at each model's posted provider rate with no markup. A 5.5% platform fee (with an $0.80 minimum) is charged when you purchase credits by card, or a flat 5% for crypto.
Does OpenRouter mark up model prices?
No. OpenRouter does not mark up provider pricing — input and output tokens are billed at the underlying provider's posted rates. Its revenue comes from the platform fee on credit purchases.
Is there a free tier?
Yes. You can use 25+ free models with no credit card, limited to 50 requests per day and 20 per minute. Purchasing at least $10 in credits raises the free-model limit to 1000 requests per day.
What is BYOK and does it cost extra?
Bring Your Own Key lets you route requests through OpenRouter using your own provider API keys. The first 1 million BYOK requests per month are free; beyond that a 5% fee of the equivalent OpenRouter model cost applies.
Does OpenRouter have an API?
Yes. OpenRouter is fundamentally an API product with an OpenAI-compatible endpoint, so existing OpenAI SDK code works by changing the base URL and key. There is no standalone desktop or mobile app.
