What this tool answers

• The one line that changes in an existing integration
• Ready-to-paste code for Python, Node.js, cURL, and .env files
• The models that are available on Aether API next to the OpenAI ones
• What to check before you switch a production key over

How it calculates

• Aether API speaks the OpenAI protocol, so the request format, the SDK, and the error format stay the same.
• Only the base URL and the key change, which is why the migration is a configuration change and not a rewrite.
• Billed per token against prepaid credits, with per-key spend limits and no minimum commitment.

Frequently asked questions

Do I have to change my code to use Aether API?

No. Point the OpenAI SDK at https://api.aetherapi.dev/v1 instead of the OpenAI host and swap the API key. The request body, the response shape, and the error format are unchanged.

Which models can I use after the switch?

Every model in the catalogue, not only OpenAI models: Anthropic, Google, xAI, DeepSeek, Alibaba, Mistral, and more, all through the same key and the same endpoint.

How do I know the switch worked?

Send one request with a small prompt and read the usage of the response. The dashboard then shows the request, its cost, and the key it was billed to.
