FAQ
Questions, answered.

    

      
How is usage billed?
New accounts get 50 free credits. Everything runs on prepaid credits: 1 credit = $0.005, packs from $5. Language models are charged per input and output token after each response; image, video and voice are charged per generation. Every request shows the exact credits used in your dashboard.

      
Is it compatible with the OpenAI and Anthropic SDKs?
Yes. Use https://apillms.com/v1 as the base URL for OpenAI SDKs, or https://apillms.com for the Anthropic SDK. Streaming, tools and vision work the same way.

      
Can I use it with Claude Code or Codex?
Yes. The dashboard gives you a one-line setup command that configures Claude Code or Codex to use your apillms key.

      
What happens if a request fails?
You are not charged for failed or empty LLM responses. Image and video credits are reserved when the job starts and refunded automatically if generation fails.

      
Do credits expire?
No, credits stay on your account while it remains active. See our refund policy for unused credits.

      
Which content is not allowed?
Voice cloning of real people without consent, sexual content, content that infringes copyright, and anything illegal. See the Terms of Service.
