Set your environment values

Replace the example values with the base URL, token and tenant identifier supplied for your project environment.

export LCE_BASE_URL="https://api.example.com"
export LCE_TOKEN="<jwt-token>"
export LCE_TENANT_ID="1"

The API definitions use an environment-specific server placeholder. Do not use localhost defaults outside a local LCE installation.

Query available languages

This request calls POST /metadata/query/languages. It is read-only and returns language metadata available to the current tenant.

curl --request POST \
  --url "$LCE_BASE_URL/metadata/query/languages" \
  --header "Authorization: Bearer $LCE_TOKEN" \
  --header "Content-Type: application/json" \
  --data "{
    \"tenantId\": $LCE_TENANT_ID,
    \"pageIndex\": 0,
    \"pageSize\": 20
  }"

Inspect the response

A successful request returns HTTP 200. The response contains a result collection and count fields. The exact records depend on your environment configuration.

{
  "result": [
    {
      "languageId": 1,
      "name": "English",
      "code": "en",
      "isDefault": true
    }
  ],
  "resultCount": 1,
  "totalCount": 1
}

Abbreviated example; service envelopes can include additional diagnostic fields.

Call the API from JavaScript

const response = await fetch(
  \`${process.env.LCE_BASE_URL}/metadata/query/languages\`,
  {
    method: "POST",
    headers: {
      "Authorization": \`Bearer ${process.env.LCE_TOKEN}\`,
      "Content-Type": "application/json"
    },
    body: JSON.stringify({
      tenantId: Number(process.env.LCE_TENANT_ID),
      pageIndex: 0,
      pageSize: 20
    })
  }
);

if (!response.ok) {
  throw new Error(\`LCE request failed: ${response.status}\`);
}

const data = await response.json();
console.log(data.result);
