```

**Key features:**

- 🔀 **Smart routing** — Priority-based with automatic fallback. If one provider is down, your request goes to the next.

- 🔄 **Format translation** — Send OpenAI format, get Anthropic response (or vice versa). TexAPI handles conversion.

- 📊 **Real-time analytics** — Usage per model, per key, per day. Costs, latency, error rates in your dashboard.

- 🔒 **Security** — Keys hashed (HMAC-SHA256), upstream creds encrypted (AES-256-GCM), zero content storage.

- 💰 **Spending controls** — Daily cap, per-key monthly limits, real-time balance tracking.

- 🤝 **Referral program** — Earn 5% commission on every top-up from users you invite. Permanent.

## Code Examples

Python — Streaming

```python

from openai import OpenAI

client = OpenAI(api_key="tex-YOUR_KEY", base_url="https://texapi.dev/v1")

stream = client.chat.completions.create(

    model="claude-sonnet-4-5",

    messages=[{"role": "user", "content": "Write a Python quicksort"}],

    stream=True,

)

for chunk in stream:

    print(chunk.choices[0].delta.content or "", end="")

```

Node.js / TypeScript — Streaming

```typescript

import OpenAI from "openai";

const client = new OpenAI({ apiKey: "tex-YOUR_KEY", baseURL: "https://texapi.dev/v1" });

const stream = await client.chat.completions.create({

  model: "claude-sonnet-4-5",

  messages: [{ role: "user", content: "Explain async/await in TypeScript" }],

  stream: true,

});

for await (const chunk of stream) {

  process.stdout.write(chunk.choices[0]?.delta?.content || "");

}

```

cURL — Non-streaming

```bash

curl https://texapi.dev/v1/chat/completions \

  -H "Authorization: Bearer tex-YOUR_KEY" \

  -H "Content-Type: application/json" \

  -d '{

    "model": "gpt-5.4",

    "messages": [{"role": "user", "content": "Hello!"}],

    "max_tokens": 100

  }'

```

Anthropic Messages API (native)

```bash

curl https://texapi.dev/v1/messages \

  -H "Authorization: Bearer tex-YOUR_KEY" \

  -H "Content-Type: application/json" \

  -H "anthropic-version: 2023-06-01" \

  -d '{

    "model": "claude-sonnet-4-5",

    "max_tokens": 1024,

    "messages": [{"role": "user", "content": "Explain quantum computing"}]

  }'

```

## FAQ

Is my data safe?

Yes. TexAPI does not store any request or response content. Only metadata (token counts, latency, model used) is logged for billing and analytics purposes.

Can I use this in production?

Absolutely. The Business plan supports 3,000 RPM, 100 API keys, and 99.9%+ uptime with multi-provider fallback.

What payment methods are accepted?

VietQR bank transfer (instant) — works with all Vietnamese banks. International payment methods coming soon.

Do credits expire?

Top-up credits never expire. Subscription credits expire at the end of each billing period.

What happens if a provider goes down?

TexAPI automatically routes your request to the next available provider. You don't need to change anything.
