• Basic usage
• Getting available providers
  • Filtering providers by capabilities
• Getting information about a provider

Basic usage

To detect or extract text within an image, send a POST request to Intento API at https://api.inten.to/ai/image/ocr. Specify the source image and the desired provider in JSON body of the request as in the following example:

curl -XPOST -H 'apikey: YOUR_API_KEY' 'https://api.inten.to/ai/image/ocr' -d '{
    "context": {
        "image": "..."
    },
    "service": {
        "provider": "ai.image.ocr.abbyy.cloud_ocr"
    }
}'

The response contains the results:

{
    "results": "...",
    "meta": {},
    "service": {
        "provider": {
            "id": "ai.image.ocr.abbyy.cloud_ocr"
        }
    }
}

If the provider doesn't have capabilities (e.g. language) to process request, 413 error will be returned:

{
  "error": {
    "code": 413,
    "message": "Provider ai.image.ocr.abbyy.cloud_ocr constraint(s) violated."
  },
  "request_id": "..."
}

Getting available providers

To get a list of available providers, send a GET request to https://api.inten.to/ai/image/ocr.

curl -H 'apikey: YOUR_INTENTO_KEY' 'https://api.inten.to/ai/image/ocr'

The response contains a list of the providers available for given constraints:

[
    {
        "id": "ai.image.ocr.microsoft.vision_api.1-0",
        "name": "Microsoft",
        "description": "Computer Vision API",
        "own_auth": true
    }
]

Filtering providers by capabilities

The list of providers may be further constrained by adding desired parameter values to the GET request:

curl -H 'apikey: YOUR_INTENTO_KEY' 'https://api.inten.to/ai/image/ocr?own_auth=true'

Response:

[
    {
        "id": "ai.image.ocr.google.cloud_vision_api.1-1",
        "description": "API Detect Labels",
        "name": "Amazon Rekognition",
        "integrated": false,
        "own_auth": true,
