## One platform, three ways to buy

Pay as you go, commit to a monthly volume, or sell the platform under your brand. All three use the same models and routing.

### 1. One API key: Pay per token for every model

Prepaid credits, with routing, fallbacks, caching and per-team analytics included.

[See pricing](https://llmapi.ai/pricing/)

### 2. Volume: Lower prices for committed volume

Commit to a monthly spend and get custom discounts on frontier models, with no change to your code.

[See volume pricing](https://llmapi.ai/pricing/#volume)

### 3. White label: Your own LLM gateway, under your brand

Your domain, prices and customers on our routing platform, live in a few weeks.

## Switch in two lines

LLM API speaks the OpenAI and Anthropic APIs. Keep the SDK you use; change the base URL and the key.

1. **Create a key**: Sign up and top up credits.
2. **Point the SDK at LLM API**: The two highlighted lines.
3. **Call each model through its own API**: Claude through Messages, GPT through Responses, open models through Chat Completions. Every model page shows its code.

Chat Completions, `POST /v1/chat/completions`, DeepSeek V4.1 Flash:

```python
import os

from openai import OpenAI

client = OpenAI(
    base_url="https://api.llmapi.ai/v1",
    api_key=os.environ["LLMAPI_KEY"],
)

response = client.chat.completions.create(
    model="deepseek/deepseek-v4.1-flash",
    messages=[{"role": "user", "content": "Hello"}],
)
print(response.choices[0].message.content)
```

## Frequently asked questions

**Q: What is an LLM gateway?**

A: An LLM gateway is one API in front of many model providers. Your app sends every request to one endpoint. The gateway picks a provider, falls back to another when one fails, and records usage and cost per team.

**Q: Is LLM API compatible with the OpenAI SDK?**

A: Yes. LLM API implements the OpenAI Chat Completions and Responses APIs. Point your OpenAI SDK at https://api.llmapi.ai/v1, use your LLM API key and call any model by its ID.

**Q: How much cheaper is LLM API than buying from providers directly?**

A: Up to 30% below provider list prices. Each model page shows what you pay per 1M tokens. Committed volume gets custom discounts on top.

**Q: Which models can I use?**

A: 394 models from 31 labs: 159 text, 139 video, 67 audio, 20 image and 9 embedding models. Labs include OpenAI, Anthropic, Google, DeepSeek, Mistral, xAI, Alibaba (Qwen) and Moonshot AI. The models page lists every model with its price.

**Q: Is LLM API ready for enterprise use?**

A: Yes. You get per-team attribution and budgets, model policies, zero-retention routes and audit logs. Contracts include an MSA, a DPA and an SLA. LLM API is SOC 2 compliant, ISO 27001 certified, and compliant with GDPR and CCPA.
