Authentication

How to get your API token

  1. Sign in and buy a credit pack on your Credits page
  2. Navigate to your Dashboard
  3. Click "Create New Token" in the API Tokens section
  4. Give your token a descriptive name
  5. Copy the token immediately (it will only be shown once!)

Using your token

Include your API token in the Authorization header of all requests:

Authorization: Bearer YOUR_API_TOKEN

Security warning: Never expose your API token in client-side code or public repositories. Store it securely and only use it in server-side applications.

Base URL

https://aipictureanswer.com/api/v1

All API requests should use Content-Type: application/json

API endpoints

POST /api/v1/solve

Solve a homework problem using EITHER a text question OR an image (not both).

Important: You must provide exactly one of these fields. Sending both question and image together will result in a validation error.

Request Body (Option 1: Text Question)

{
  "question": "Solve: 2x + 5 = 15"
}

Request Body (Option 2: Image Only)

{
  "image": "data:image/jpeg;base64,/9j/4AAQSkZJRg..."
}

Note: Images must be base64 encoded with the data URI prefix (e.g., data:image/jpeg;base64,...)

Response (200 OK)

{
  "success": true,
  "data": {
    "answer": "Step 1: Subtract 5 from both sides...",
    "conversation_id": 12345
  },
  "usage": {
    "requests_today": 15,
    "is_unlimited": true
  }
}

Error Responses

Rate limits & best practices

Pay per successful solve

Each successful API solve uses one credit. Failed requests are free and credits never expire.

Secure token storage

Store your API tokens securely using environment variables or secrets management.

HTTPS only

All API requests must use HTTPS for security.

Error handling

Always implement proper error handling for failed requests.

Don't expose tokens

Never expose your API tokens in client-side code, public repositories, or browser JavaScript.
