Questions

How fast do the credits arrive?

Instantly — the balance is credited the moment the payment confirms, and your API key starts working against it right away.

Why do I get $1000 for $100?

The gateway resells API capacity at a 10x credit multiplier: every dollar you pay becomes $10 of API credit at standard per-token rates.

Which models can I spend the credits on?

Every model on the gateway: Claude Opus, Sonnet, Haiku and Fable, plus GPT, Gemini and MiniMax — all metered from the same balance.

Is this an official Anthropic product?

No — ClaudeAPIKey.dev is an independent API gateway. You get a gateway API key and base URL that work with the standard Anthropic and OpenAI SDK formats.
