This demo aims to:

• Enable api.raunaqgupta.com
• Expose various single-function cloudflare workers under the /utilities path.
• Expose my aqicn.org API token protected endpoint under the /aqi path without exposing the token.
• Enable key authentication on all endpoints via Kong Konnect.
• Expose a basic single-response AI endpoint under the /ai path.

Enable the api sub-domain

• Kong Konnect’s free tier provides one free API gateway.
• Provisioned API gateway can be configured for a non-apex domain.

Expose a datetime utility under /utilities

• Created a Cloudflare worker to return the current date and time in JSON format with an optional timezone query parameter.
• Setup route on Kong Konnect’s API gateway to redirect to /utilities/datetime.

curl -X GET "https://api.raunaqgupta.com/utilities/datetime?timezone=PST"

}                                                                                                                                                                     

Expose an air quality index endpoint under /aqi

• Exposed aqicn.org’s feed endpoint at api.raunaqgupta.com/aqi/feed/:city without requiring to expose the API token. This endpoint takes a city name as a parameter and returns the air quality index data for that city in JSON format.
• Use Kong Konnect’s API gateway to route requests to https://api.waqi.info/feed/:city/?token=YOUR_API_TOKEN.
• Utilize the Request Transformer Advanced plugin to store the personal API token in the gateway instead of exposing it on the client side.

Notes

• Kong Konnect lets you use the Konnect vault in the Request Transformer Advanced plugin even though it’s not supported. Both copilot chat and documentation confirm this: https://developer.konghq.com/how-to/configure-the-konnect-config-store/#can-i-reference-konnect-config-store-vault-secrets-in-kong-conf

Enable key authentication on all endpoints

• Enabled the key authentication plugin on the API gateway.
• Created a consumer and assigned it a key auth credential.

Enable an AI gateway under /ai

• Used Google Gemini’s API key to connect.
• Added the prompt decorator, and a prompt template plugins.
• Existing key authentication works out of the box.
