OpenRouter Pricing 2026: Fees, Free Models and Real Cost

Short answer: OpenRouter charges each provider's list price per token with no markup, and takes its cut when you buy credits: 5.5% on Standard, 8% on Business, contract pricing on Enterprise. The Free tier offers 25+ free models capped at 50 requests a day. With your own provider keys (BYOK), the first $25,000 a month of list-price usage carries no fee. Verified on openrouter.ai, October 2026.

So the token price is never where OpenRouter costs you more. The difference sits in the credit fee, the minimum on small top-ups, and a few terms most people skip: refunds close after 24 hours and unused credits can expire after a year. Here is what each of those costs in dollars.

OpenRouter plans and fees

Fees and plan limits read on OpenRouter's pricing page, FAQ and terms on October 28, 2026.

Dupple data: Toolradar, our software directory, evaluated 501 API tools for its ranking updated October 27, 2026, and lists OpenRouter among them. The fee table below is our arithmetic on OpenRouter's printed rates, dated October 28, 2026. Toolradar's API tools ranking

Does OpenRouter mark up model prices?

No. OpenRouter's pricing FAQ says inference "is billed at the provider's list price on every plan," and the fee is "charged when you buy credits... never on individual requests." Streaming does not change the rate, and routing through openrouter/auto adds no fee: you pay whatever model serves the request.

You can check this on any model page. Claude Sonnet 5.5 lists at $2 per million input tokens and $10 per million output tokens through Anthropic, Amazon Bedrock, Google Vertex and Azure on OpenRouter, the same rate Anthropic prints on its own API pricing page. One exception worth knowing: the regional endpoints for that model (US-only and EU in-region routing) list at $2.20 and $11, about 10% more, so keeping data in a region costs extra on top of the Business plan it requires.

Failed calls are free. An attempt that errors is not charged for its model tokens, so with fallback routing you pay only for the run that answers. Add-ons that already ran, such as web search or file parsing, may still be billed.

What the credit fee costs at real budgets

The fee is a percentage of each credit purchase, so it scales with spend. All figures below are our arithmetic on OpenRouter's printed rates.

For a solo developer spending $100 a month, OpenRouter adds $66 a year over calling the same models directly. That buys one API key for 500+ models, automatic fallback between providers and budgets per key. Whether that is worth it depends on how many providers you would otherwise manage.

At the job level the fee is small. A Sonnet 5.5 job of 1 million input and 1 million output tokens costs $12 at list price; paid from Standard credits it works out to $12.66. On Business, the same job costs $12.96.

Business costs $300 a year more than Standard at $1,000 a month (our arithmetic). What it adds: EU and US in-region routing, 1,000 workspaces instead of 5, advanced notifications and workload identity federation. If you need none of those, stay on Standard; OpenRouter says model prices are identical on both.

Is OpenRouter free?

Partly. The Free tier needs no purchase and gives access to 25+ free models from 4 free providers, with chat, API access and activity logs. It does not include auto-routing, budgets, prompt caching or BYOK.

The limits are tight. Free models are capped at 20 requests a minute and 50 a day, and failed attempts count toward the daily cap. Once your account has bought at least $10 of credits, the cap rises to 1,000 requests a day. A negative balance blocks free models until you top up.

So the cheapest useful setup is a single $10 purchase. On Standard that costs $10.80 with the minimum fee described below, and it lifts the free-model cap twentyfold. For a hobby project that runs on free models, that is the whole bill.

How BYOK pricing works

With BYOK (bring your own key), you plug your own provider account into OpenRouter, and the provider bills you directly for tokens. OpenRouter charges nothing on the first $25,000 of list-price usage a month on Standard and Business, then 5% of what the same requests would cost at list price on OpenRouter, deducted from your OpenRouter credits.

Most teams never reach the allowance. A team running $30,000 a month of list-price traffic through BYOK pays the fee only on the $5,000 above it, which is $250 a month or $3,000 a year (our arithmetic). Compare that with buying the full $30,000 as Standard credits, where the Standard fee would be $1,650 a month.

BYOK makes sense when you already hold committed-spend discounts or higher rate limits with a provider. You keep your own provider terms and use OpenRouter only as the router.

Hidden costs to budget for

These come from OpenRouter's pricing page, FAQ and terms of service, read October 28, 2026.

• A $0.80 minimum fee on small top-ups. OpenRouter's FAQ lists the Standard fee as "5.5% ($0.80 minimum)." A $5 purchase, the smallest the terms allow, carries a 16% fee; the minimum stops mattering above about $14.55 per purchase (our arithmetic). Top up in larger amounts or use auto top-up with a higher threshold.
• A separate fee on crypto. The FAQ states that crypto payments are charged a 5% fee, and the terms say crypto payments are never refundable.
• A 24-hour refund window. Unused credits can be refunded only within 24 hours of purchase, and the platform fee is not refunded even then.
• Credit expiry. The terms reserve the right to expire unused credits 365 days after purchase. Do not prepay a year of usage to save on fees.
• Purchase limits. Each transaction is between $5 and $25,000, per the terms. Larger buyers move to Enterprise for invoicing.
• Taxes. Prices exclude VAT and GST, which may be added on invoices.
• Price changes. If a provider changes a model's price, OpenRouter keeps routing to it and charges the new rate. Pin a model version and watch the model page if your margins are thin.

Is OpenRouter cheaper than calling the provider directly?

No, not on token price. The tokens cost the same, and the credit fee comes on top, so the same traffic through OpenRouter always costs more than through a direct key, by at least the credit fee. Provider-side discounts also stay with the provider: Anthropic, for example, prints 50% off for batch processing on its own API, so compare your actual route before assuming parity.

OpenRouter earns its fee in three situations. You use models from several providers and want one key and one bill. You want automatic fallback when a provider is down, which keeps an app answering when one provider fails. Or you want to switch models without changing code, since the API is OpenAI-compatible. If you call one model from one provider, go direct.

FAQ

How we checked these prices

We read OpenRouter's pricing page, FAQ, terms of service and the Claude Sonnet 5.5 model page on October 28, 2026, and compared the model rate with Anthropic's API pricing on the same day. The scenarios use $100, $1,000 and $10,000 of monthly model spend; every total is our arithmetic on printed rates. Model prices move often, so check the model page before you budget.
