Check your usage

Balance and allowance from the console or GET /v1/key.

The easiest way to see what you have left is the console overview: balance, plan allowance, free tokens and recent requests. Console → Usage lists every request and what it cost.

From code: GET /v1/key

curl https://api.aivokey.dev/v1/key \
  -H "Authorization: Bearer sk-aivo_..."

Example answer for a pay-as-you-go account:

  "fallback_enabled": false,
  "free_tokens": [
    { "model": "deepseek-v4-pro", "remaining": "180000" }
  ],
  "models": []
}

Fields

`fallback_enabled`	Whether this key may use the balance when the plan cannot serve a request.
`free_tokens`	Free tokens left per model (only shown when you have some).
`plan`	Plan name and type (plan accounts only).
`models`	Per-model plan allowance with `5h`, `7d` and `month` windows: `limit`, `used`, `reset_at`.
