Free GPT Grok Gemini Claude API
One OpenAI-compatible API key routing to OpenAI, Anthropic, Google, and 100+ open-source models.
OkRouter is worth a test drive if you are already writing against the OpenAI SDK and want to stop managing separate OpenAI, Anthropic, and Google accounts. The migration is a two-line change (API key plus base URL), the free tier's 50 requests per day lets you confirm the claimed ~20% token savings before you commit, and prompt caching plus budgets and spend controls are genuinely useful once you are in production. The trade-offs are real: smart routing picks the provider for you, which will not suit teams that need strict vendor control, and the free tier's 50 requests per day is only enough for evaluation. Compare it against OpenRouter, which has a more mature ecosystem and broader

Skip OkRouter if you need to pin every request to one specific vendor with no routing layer in between, or if your workload has to run offline or on-premise rather than through a hosted gateway.
Every paid-plan request is billed at model-based token pricing with no minimum spend, so a busy month on premium models can outrun the ~20% savings you came for.
Free fits a solo developer or small team evaluating multi-model routing at 50 requests per day. Pay-as-you-go with no minimum spend suits indie hackers and startups whose token volume is unpredictable. Enterprise custom pricing with volume commitments is for larger orgs that need SSO, SOC2, admin controls, and a dedicated rate limit. Against OpenRouter, OkRouter competes on the claimed ~20% token savings and its 500+ model catalog; going direct to a single provider is the cheaper route only if

About Free GPT Grok Gemini Claude API
OkRouter is an API gateway that lets you reach OpenAI, Anthropic, Google, Meta, Mistral, Cohere, DeepSeek, and other providers through a single key and a single endpoint. You keep using the official OpenAI SDK—Python, Node.js, Go, or Java—and change only your API key and base URL (https://api.okrouter.com/v1) so the same code runs against 500+ models. Requests are routed to the fastest available provider in real time, and the gateway handles failover when a provider goes down. Beyond routing you get prompt caching to trim token spend, activity logs with export, budgets and spend controls, rate-limit management, and API key management. The free tier covers 25+ models from 6 providers plus chat and API access through the web console, capped at 50 requests per day. Pay-as-you-go removes the minimum spend and opens the full catalog of 500+ models across 60+ providers, with auto routing, preferred vendor selection, and email support. Enterprise adds admin controls, an optional dedicated rate limit, volume commitments, SSO, SOC2, and a support SLA with a shared Slack channel. OkRouter positions itself as roughly 20% cheaper on token costs than going direct or using OpenRouter, and it says it is trusted by 500+ engineering teams with developers from Google, Meta, Vercel, and Shopify. It is a gateway rather than a model provider, so it suits developers and teams consolidating vendor accounts rather than people wanting a no-code AI app.
Behind the Verdict
The core of OkRouter is a compatibility trick done well: because it speaks the OpenAI API format, your existing code becomes multi-provider by changing api_key and base_url to https://api.okrouter.com/v1. The docs show working examples in Python, Node.js/TypeScript, Go, and Java, plus curl, and they spell out the OpenAI and Anthropic migration paths explicitly. That is the strongest part of the product—it lowers the cost of trying it to near zero for anyone already on the OpenAI SDK. The second layer is routing and reliability. Smart routing picks the fastest provider for each request in real time, and failover keeps your app alive if a provider has an outage. For multi-model apps this removes a lot of plumbing you would otherwise write yourself. The third layer is cost and governance. Prompt caching reduces token spend, budgets and spend controls cap what you can burn, and activity logs with export give you an audit trail. On the free tier you get 25+ models from 6 providers and web-app chat plus API access, but only 50 requests per day, so it is an evaluation lane rather than a production one. Pay-as-you-go opens 500+ models across 60+ providers with no minimum spend and model-based token pricing; Enterprise adds SSO, SOC2, admin controls, an optional dedicated rate limit, a support SLA with a shared Slack channel, and volume commitments. Where it fits: AI-native startups and indie hackers who call several models and want one bill, one key, and one SDK; engineering teams consolidating vendor accounts; and enterprises that need SSO and SOC2 on top of a routed gateway. Where it does not: anyone who needs no-code, anyone who needs offline or on-premise deployment, and anyone who must pin a specific vendor per request—smart routing decides for you, though paid plans do add preferred vendor selection. The vendor claims ~20% savings versus direct or OpenRouter, but that depends entirely on your traffic mix and which models you actually call, so verify against your own usage before moving production workloads over.

Real-world workflow fit
Concrete scenarios for the personas Free GPT Grok Gemini Claude API actually fits — and what changes day-one when you adopt it.
You sign up at okrouter.com/signup, generate a key in the dashboard, and point the OpenAI SDK at https://api.okrouter.com/v1 with your OkRouter key. You get a key and run your first request from the web console or curl on the free tier's 25+ models at 50 requests per day.
Outcome: One key and one SDK call across OpenAI, Anthropic, Google, and open-source models without opening separate provider accounts.
You migrate existing OpenAI and Anthropic code by changing only the API key and base URL, turn on smart routing and preferred vendor selection, then set budgets and spend controls plus activity log export before moving production traffic.
Outcome: A single bill and one integration surface, with failover covering provider outages and prompt caching trimming token spend.
You negotiate Enterprise for SSO, SOC2, admin controls, and an optional dedicated rate limit, and route the full 500+ model catalog across 60+ providers behind your existing governance, with a shared Slack support channel for the SLA.
Outcome: Routed multi-provider access that fits existing identity and compliance requirements instead of a stack of separate vendor contracts.
Use Cases
- Consolidate separate OpenAI, Anthropic, and Google API keys into a single endpoint and key

Models Under the Hood
as of 2026-09-23
Limitations
- OkRouter is an API gateway, not a model provider, so what you can call depends on the underlying providers and on your plan.
- The free tier is capped at 50 requests per day and 25+ models from 6 providers, which is an evaluation lane rather than a production one.
- Token pricing is model-based on the paid plans, so your bill depends entirely on which models and how many tokens you send.
- Enterprise features such as SSO, SOC2, admin controls, and a dedicated rate limit sit behind custom pricing and volume commitments.

How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From OpenAI: change api_key to your OkRouter key and set base_url to https://api.okrouter.com/v1, then use openai/gpt-4o style model names
- →From Anthropic: follow the docs migration guide to move calls onto the OpenAI-compatible OkRouter endpoint
- →From managing multiple provider accounts: replace each vendor key with one OkRouter key and one endpoint
- →From a single-provider SDK integration: swap the base URL and pick your models from the 500+ catalog
- ↗To OpenAI direct: point base_url back to the OpenAI API and revert model names to plain gpt-4o
- ↗To Anthropic direct: re-add the Anthropic SDK and key for the calls you routed through OkRouter
- ↗To OpenRouter: re-point your OpenAI-compatible client to OpenRouter's base URL and model names
- ↗To a single provider: if your traffic only ever hits one model, drop the gateway and call that provider directly
