Introduction
ApiFlux is an AI router that connects developers to 100+ frontier models through one simple API key. It supports native Anthropic, OpenAI, and Gemini APIs, and includes automatic failover and transparent per-token pricing. The ApiFlux AI router also works with Claude Code right away, so teams can point existing tools at a single endpoint without rewriting code.
What is ApiFlux?
ApiFlux is a cloud-based AI router built for developers who want one key to access many models. Instead of signing up for separate provider accounts, users create one API key and use it across all supported models. The service works with native Anthropic, OpenAI, and Gemini APIs, which means it acts as a bridge between an application and the model provider.
The main problem the service solves is provider fragmentation. A developer can run Claude Code, use an OpenAI SDK, or call Gemini without switching accounts. It also handles automatic failover, so if one provider has an outage, requests move to a healthy model before users notice. This makes the platform useful for AI coding tools, production applications, and small teams that need a reliable AI router without extra setup.
The service is suitable for developers who want transparent per-token pricing. Every model is billed at 85% of the OpenRouter list price, and the dashboard shows exact costs per request. It matters because token costs can be unpredictable with subscriptions or bundled plans. With ApiFlux, users pay only for what they send and receive, while keeping access to 100+ models.
Key Features of ApiFlux
100+ Frontier Models
The router provides access to Claude, GPT, Gemini, DeepSeek, Kimi, Qwen, and more from one endpoint. This makes it easy to test different models without creating multiple accounts.
Transparent Per-Token Pricing
ApiFlux charges every model at 85% of the OpenRouter list price. The dashboard shows the exact cost of every request, so there are no surprise subscription fees.
OpenAI-Compatible API
The service uses an OpenAI-compatible API. Developers can point any OpenAI SDK at ApiFlux by changing the base URL, keeping the rest of the code unchanged.
Automatic Failover
When an upstream provider slows down or fails, the AI router reroutes traffic to another healthy path. This helps keep applications online during provider incidents.
Live Usage Dashboard
Users get a live view of token usage, latency, cost, and errors for every request. No extra logging or instrumentation is required.
Built for AI Coding Tools
The platform is Claude Code ready and includes guides for Codex CLI and OpenCode. Developers can make these tools use the service with a simple base URL change.
Use Cases for ApiFlux
AI Coding Tools
Developers can run Claude Code, Codex CLI, OpenCode, Pi, Hermes, or OpenClaw through the service and reduce their token bill by 15%. ApiFlux is ready for these tools with step-by-step guides.
Production Apps and Agents
Teams building chatbots, copilots, or agent pipelines can use ApiFlux as the AI router behind their product. Automatic failover helps keep production traffic moving during provider issues.
Prototypes and Side Projects
Users can top up a few dollars and try GPT, Gemini, DeepSeek, or Claude without a subscription. This is useful for quick experiments and hackathon projects.
Model Evaluation
The service makes it easy to compare Claude, GPT, Gemini, and DeepSeek on the same prompt. Users do not need to manage separate provider accounts.
Small Teams, One Balance
Small teams can share one ApiFlux balance while giving each key its own spending limit. Per-key usage logs show who spent what and on which model.
Leaving Single-Vendor Lock-In
The service keeps code OpenAI-compatible, so teams can move away from one provider without rewriting their stack. They can swap models per request while keeping the same API key.
How to Use ApiFlux
- Create an API key on the ApiFlux dashboard.
- Top up the account with a small prepaid balance.
- Point your tool at ApiFlux by changing the base URL.
- If using Claude Code, follow the setup guide to switch it to the endpoint.
- Watch usage in the live dashboard and track token cost, latency, and errors.
The whole process takes a few minutes. There is no code rewrite because the service uses an OpenAI-compatible API. This makes the ApiFlux AI router a simple drop-in for most development workflows.
Target Audience for ApiFlux
- Developers who use Claude Code, Codex CLI, OpenCode, or OpenAI SDKs
- AI engineers building agents, copilots, or chatbots
- Startups and small teams that need one shared API balance
- Side project builders who want to compare frontier models without subscriptions
- Teams looking for an AI router with automatic failover
- Companies that want to reduce dependency on a single model provider
- Enterprise teams that want a central AI gateway for routing and observing model calls
Is ApiFlux Free?
ApiFlux does not advertise a free plan. It works as a prepaid, pay-as-you-go service. Users top up once and spend credit as they make model calls. There is no monthly subscription, so developers only pay for tokens they actually use.
| Plan | Price | Features |
|---|---|---|
| Pay-as-you-go | Prepaid top-up | Access to 100+ models, one API key, OpenAI-compatible API, per-token pricing, live usage dashboard, automatic failover |
Pricing for individual models is set at 85% of the OpenRouter list price. Users can find the latest model-specific costs on the models page.
ApiFlux's Pros and Cons
| Aspect | Pros | Cons |
|---|---|---|
| Pricing | 15% below list price; no subscription; transparent per-token pricing | No free tier mentioned; requires prepaid credit |
| Setup | OpenAI-compatible API; simple base URL change; Claude Code ready | Needs a new API key and top-up before use |
| Model Access | One key for 100+ models from Anthropic, OpenAI, Google, DeepSeek, and more | Not all models may be constantly available |
| Reliability | Automatic failover protects against provider downtime | Failover behavior depends on upstream health |
Frequently Asked Questions about ApiFlux
What is an AI router?
An AI router is a service that sits between an application and multiple AI model providers. It lets developers send one request to a single endpoint, and the router decides which model handles it. ApiFlux is an AI router that supports 100+ frontier models.
How do I get started with ApiFlux?
Create an account, generate an API key, top up your balance, and point your tool or SDK at the ApiFlux base URL. Claude Code users can follow the setup guide.
Is ApiFlux compatible with the OpenAI SDK?
Yes. The service uses an OpenAI-compatible API. Most OpenAI SDK clients can connect by changing the base URL to ApiFlux, which makes migration simple.
Why is ApiFlux cheaper than going direct?
ApiFlux bills every model at 85% of the OpenRouter list price. Users get per-token pricing without subscription fees, so token costs stay low and predictable.
Which models are supported by ApiFlux?
The service supports 100+ models, including Claude, GPT, Gemini, DeepSeek, Kimi, and Qwen. The models page lists all available options.
What happens when a provider goes down?
The service uses automatic failover. If a provider degrades or fails, the AI router reroutes requests to a healthy model before users notice a problem.
