Finding Your Core API URL

This guide explains how to locate the Core API URL for your FoundationaLLM deployment.

Overview

The Core API URL depends on your deployment type:

Deployment Type	URL Pattern
Azure Container Apps (ACA)	Container app URL ending in `coreca`
Azure Kubernetes Service (AKS)	Cluster FQDN with `/core` path

Method 1: Azure App Configuration

The easiest way to find your Core API URL:

Open the Azure Portal
Navigate to your FoundationaLLM resource group
Open the App Configuration resource
Select Configuration explorer
Search for: FoundationaLLM:APIs:CoreAPI:APIUrl
Copy the value

Method 2: Azure Container Apps (ACA) Deployment

For ACA deployments:

Navigate to your FoundationaLLM resource group in Azure Portal
Find the Container App resource with a name ending in coreca

Example: fllm001coreca
In the Container App Overview pane, copy the Application Url

Example: https://fllmaca002coreca.graybush-c554b849.eastus.azurecontainerapps.io

Method 3: Azure Kubernetes Service (AKS) Deployment

For AKS deployments:

Navigate to your FoundationaLLM resource group in Azure Portal
Open the Kubernetes Service resource
Select Properties in the left menu
Copy the HTTP application routing domain
Append /core to the domain

Example: If the domain is https://1cf699fd0d89446eabf2.eastus.aksapp.io/, then the Core API URL is https://1cf699fd0d89446eabf2.eastus.aksapp.io/core

Method 4: Azure CLI

Use the Azure CLI to retrieve the URL:

For ACA:

# List container apps and find the core API
az containerapp list \
  --resource-group <your-resource-group> \
  --query "[?contains(name, 'coreca')].properties.configuration.ingress.fqdn" \
  -o tsv

For AKS:

# Get the AKS cluster's HTTP routing domain
az aks show \
  --resource-group <your-resource-group> \
  --name <your-aks-cluster> \
  --query "addonProfiles.httpApplicationRouting.config.HTTPApplicationRoutingZoneName" \
  -o tsv

Verification

Verify your Core API URL is correct by accessing the status endpoint:

curl https://{your-core-api-url}/status

Expected response:

{
  "status": "ready",
  "name": "CoreAPI",
  "version": "x.x.x"
}

Or access the Swagger UI (ACA only):

https://{your-core-api-url}/swagger/

URL Formats Summary

Deployment	Format	Example
ACA Quick Start	`https://{prefix}coreca.{env}.{region}.azurecontainerapps.io`	`https://fllmaca002coreca.graybush-c554b849.eastus.azurecontainerapps.io`
ACA Standard	`https://{prefix}coreca.{env}.{region}.azurecontainerapps.io`	`https://fllmprod-coreca.fllmenv.westus2.azurecontainerapps.io`
AKS	`https://{cluster-fqdn}/core`	`https://1cf699fd0d89446eabf2.eastus.aksapp.io/core`

Troubleshooting

URL Returns 404

Verify the URL path is correct (AKS requires /core)
Check that the Container App or AKS ingress is running

URL Returns 401/403

The API is accessible but requires authentication
This confirms the URL is correct

Cannot Access URL

Check network connectivity
Verify the deployment is running
For AKS, ensure the ingress controller is configured
