Getting started

Quick start

Get an API key and make your first request to Apixo in two minutes.

Apixo gives you one API key and one base URL for every model we offer. It speaks both the OpenAI and the Anthropic API formats, so almost any tool or SDK works by changing two settings.

Setting	Value
Base URL (OpenAI clients)	`https://api.apixoai.online/v1`
Base URL (Anthropic clients)	`https://api.apixoai.online`
API key	your `sk-apixo-…` key

1. Get your key

Sign in with Telegram — or open the Telegram bot and press Start. Your key is created instantly and shown in your dashboard.

Keep it secret: anyone with the key can spend your balance. You can rotate it any time from the dashboard or with /regenerate in the bot.

2. Make a request

export APIXO_API_KEY="sk-apixo-..."

curl https://api.apixoai.online/v1/chat/completions \
  -H "Authorization: Bearer $APIXO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "gpt-6-astra", "messages": [{"role": "user", "content": "Hello!"}]}'

Or with the Anthropic format:

curl https://api.apixoai.online/v1/messages \
  -H "x-api-key: $APIXO_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{"model": "claude-fable-5", "max_tokens": 512, "messages": [{"role": "user", "content": "Hello!"}]}'

3. Connect your tool

Pick your tool in the sidebar — each guide has a ready-to-paste config. In the dashboard you can download these files with your key already filled in.

4. Top up

New accounts may receive a small trial credit that works on selected models. Top up with crypto to unlock every model — your balance is credited after one blockchain confirmation. Requests need a balance of at least $0.01.

Tip: list the models available to you with curl https://api.apixoai.online/v1/models.
