Every API request needs two headers: your API key and your project ID. No OAuth, no tokens to refresh.

​
Required headers

HeaderValue
x-api-keyYour API key from the dashboard
x-project-idYour project UUID from the dashboard
content-typeapplication/json

​
Example

curl --location 'https://api.zerogpu.ai/v1/responses' \
  --header 'content-type: application/json' \
  --header 'x-api-key: YOUR_API_KEY' \
  --header 'x-project-id: YOUR_PROJECT_ID' \
  --data '{ ... }'

​
Where to find credentials

  1. Log in at zerogpu.ai
  2. Select your project
  3. API Key and Project ID are on the dashboard

​
When it goes wrong

StatusCauseFix

API keys go in server-side code only. Never in frontend JavaScript, mobile apps, or git repos. See Security.
