Authenticatie

Om te authenticeren, gebruik deze code:

# With shell, you can just pass the correct header with each request
curl "api_endpoint_here" \
  -H "Authorization: Bearer i18n_your_api_key_here"

const headers = {
  'Authorization': 'Bearer i18n_your_api_key_here',
  'Content-Type': 'application/json'
};

fetch('api_endpoint_here', { headers })
  .then(response => response.json())
  .then(data => console.log(data));
```python import requests

headers = {
'Authorization': 'Bearer i18n_your_api_key_here',
'Content-Type': 'application/json'
}

response = requests.get('api_endpoint_here', headers=headers)
print(response.json())


```go
package main

import (
    "net/http"
)

func main() {
    client := &http.Client{}
    req, _ := http.NewRequest("GET", "api_endpoint_here", nil)
    req.Header.Add("Authorization", "Bearer i18n_your_api_key_here")
    
    resp, _ := client.Do(req)
    defer resp.Body.Close()
}

Make sure to replace i18n_your_api_key_here with your API key.

The i18n-agent API uses API keys to allow access to the API. You can get your API key from your account dashboard.

Bewaking

The API key must be included in all API requests to the server in a header that looks like the following:

Gezondheidscontrole

GET /health
You must replace i18n_your_api_key_here with your personal API key.
Controleer de gezondheidsstatus van de service

curl -X GET "https://api.i18nagent.ai/health" \
  -H "Authorization: Bearer i18n_your_api_key_here" \
  -H "Content-Type: application/json"
