APIONE developer documentation

Connect your application or compatible client with an APIONE API Key, an API address, and a model ID.

Compare available models, capabilities, prices, and channels in APIONE.

Start here

Build an application

Create a key, list models, and make your first request with cURL.

Configure a client

Choose your tool and enter its API address, key, and model settings.

Step	Action	Check after completion
1. Sign in	Open the APIONE console and sign in	Confirm the current account is correct
2. Prepare balance	Check balance or plans on the account page; recharge or purchase as needed	Payment status, credited amount, and available balance match
3. Web experience	Choose an available model, send a short question, and follow up	Receive a complete response that carries context

Web chat and API usage share APIONE balance. Plan allowances, credited balance, and reward points each have their own rules; see Usage and costs and Points and referral rewards. You can complete the first three steps if you only want to try web chat. When you are ready to code or use a client, go to Quickstart or Client guides.

Three settings you need

Setting	Where to get it	Purpose
API Key	Console API Keys	Authenticates requests and applies the key’s model permissions and billing group
Base URL	API addresses and authentication	Tells the SDK or client where to send requests
Model ID	Model directory or models API	Selects a model available to your key
