Replace YOUR_API_KEY and choose one of the providers: openai | anthropic | aws | openrouter | chutes | akash | nvidia | google

curl -X POST https://nano-gpt.com/api/v1/chat/completions \
  -H "x-api-key: YOUR_API_KEY" \
  -H "x-use-byok: true" \
  # Optional but recommended: force provider mapping when in doubt \
  -H "x-byok-provider: openai" \
  -H "content-type: application/json" \
  -d '{
    "model": "gpt-4o-mini",
    "messages": [
      {"role": "user", "content": "Say hello from BYOK"}
    ]
  }'

What is the pricing?

We charge a 5% markup on the normal at-cost API rates. Your provider bills you directly; we only charge the markup.

What if I use a free model via BYOK?

If the model that you use is free via the original provider where you use it from we base our 5% markup on what the lowest rate would be if you used the paid version of it. If you for example use an API key that has free requests for gemini-2.5-pro, we will charge the 5% markup based on regular gemini-2.5-pro pricing.

Which endpoint supports BYOK?

BYOK is currently supported only on the OpenAI-compatible endpoint /api/v1/chat/completions.

Do I have to set x-byok-provider?

No. It’s optional. We auto-map based on the model. Setting it is recommended if you want to force a specific provider.

How do I use Google Gemini AI Studio?

Add your Google AI Studio key above, then set the header x-byok-provider: google when calling /api/v1/chat/completions. This forces routing through Google AI Studio for Gemini models.

What usage counts are used for billing?

We prefer provider-reported usage tokens when available (streaming or final usage). If unavailable, we estimate conservatively.

How are keys stored?

Keys are encrypted at rest. We only store the last 4 characters for display and never send keys back to the client.
