This project started at the Open Source Night at CHECK24. We only had ~2 hours to build a first proof of concept. The proof of concept already works. But the quality isn't ready for production. Until this is fixed, this project is still in progress.

With "AltTextAPI" you can get the alt text of an image. Just call the API (https://alttextapi.com/v0/image-to-alt-text) with the image URL and you will get the alt text as a response.

curl -X GET -H "Content-Type: application/json" https://alttextapi.com/v0/image-to-alt-text?imageUrl=IMAGE_URL&contextPrompt=CONTEXT_PROMPT

Example:

curl -X GET -H "Content-Type: application/json" https://alttextapi.com/v0/image-to-alt-text?imageUrl=https%3A%2F%2Ffirebasestorage.googleapis.com%2Fv0%2Fb%2Falt-text-api.appspot.com%2Fo%2Falt-text-api-demo.png%3Falt%3Dmedia%26token%3D5b340e2a-d807-4da9-9ba2-25c772df3e30
