Turn this quarterly report into three key takeaways

Claude Sonnet 4.5

Here are the three takeaways from Q3:

  1. Revenue grew 18% quarter over quarter, ahead of plan.
  2. Enterprise accounts drove most of the growth.
  3. Support costs fell as self-serve usage rose.

One API for
every AI model.

Works with the OpenAI, Anthropic and Gemini SDKs. Change the base URL, keep the rest of your code.

When a provider goes down,
your app doesn't.

Every model runs on multiple providers. If one fails, your request reroutes automatically.

Questions,
answered.

Everything to know before you start. Still curious? We're happy to help.

Talk to us
Is APIONE cheaper than the official APIs?

Yes. APIONE bills model calls below the official API price and offers several discount groups to choose from. Actual charges follow the rates shown on the model pricing page and your usage invoices.

Do web chat and the API share one balance?

Yes. Web chat, images, video and API calls all draw on the same APIONE account balance.

Is my data stored or used for training?

APIONE does not use your data to train models. Requests are forwarded to the model provider you selected as needed to serve them; see the APIONE privacy policy and that provider's privacy policy for details.

What happens if an upstream provider fails?

When the current route is unavailable, smart routing automatically switches to another available route for the same model so requests still complete.

Do I need to change my code to use APIONE?

In most cases no business-code changes are needed. Keep using the OpenAI, Anthropic or Gemini SDK — just replace the base URL and use an APIONE API key.

Does my balance expire?

Pay-as-you-go balance never expires. Subscription credit is valid for 30 days from the date it is issued. See the plan page for details.
