Question 1

How does the $5 free credit offer work?

Accepted Answer

New accounts automatically receive $5 in free credits upon sign-up — no credit card is required. You can use these credits to test all frontier models immediately.

Question 2

How do I integrate NexGate into my application?

Accepted Answer

NexGate is fully compatible with the OpenAI SDK. Simply update your baseURL to 'https://api.nexgate.app/v1' and replace the API key with your NexGate key. Your existing code will work without any other changes.

Question 3

Which AI models can I route requests to?

Accepted Answer

NexGate provides access to leading frontier models through a single endpoint, including GPT-5.5, DeepSeek-V4 Pro, Kimi K2.6, Grok 4.3, and Llama 4. See the full catalog on the Models page.

Question 4

What are granular spend controls?

Accepted Answer

You can configure hourly, daily, or absolute spending limits on individual API keys to prevent unexpected runaway API bills from loops or testing errors.

Question 5

Do my prepaid credits expire?

Accepted Answer

No. All credits purchased on NexGate roll over indefinitely and never expire. You only pay for what you consume with zero recurring monthly subscriptions.

Question 6

How is token usage calculated?

Accepted Answer

NexGate calculates token usage dynamically based on the exact provider token pricing (input and output) times a minimal transparent margin. Per-request pricing is available instantly in your usage log.
