# Errors
> Standard error codes and handling
## Error format
All errors return a consistent JSON structure:
```json theme={null}
{
"error": "Unauthorized",
"message": "Invalid or missing API key",
"status": 401
}
```
## Status codes
| Code | Name | Description |
| ----- | --------------------- | -------------------------- |
| `200` | OK | Request successful |
| `400` | Bad Request | Invalid parameters |
| `401` | Unauthorized | Missing or invalid API key |
| `404` | Not Found | Resource not found |
| `429` | Too Many Requests | Rate limit exceeded |
| `500` | Internal Server Error | Server-side error |
| `503` | Service Unavailable | Temporary maintenance |
## Handling errors
```javascript Node.js theme={null}
try {
const response = await fetch('https://api.fieldfunded.com/v1/events', {
headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
if (!response.ok) {
const error = await response.json();
console.error(`Error ${error.status}: ${error.message}`);
return;
}
const data = await response.json();
} catch (err) {
console.error('Network error:', err);
}
```
```python Python theme={null}
import requests
response = requests.get(
'https://api.fieldfunded.com/v1/events',
headers={'X-API-Key': 'YOUR_API_KEY'}
)
if response.status_code != 200:
error = response.json()
print(f"Error {error['status']}: {error['message']}")
else:
data = response.json()
```
