Errors

The API uses standard HTTP status codes and returns a consistent JSON error format.

​
Error response format

All error responses follow this structure: 
{
  "success": false,
  "error": {
    "code": "NOT_FOUND",
    "message": "Equipment not found"
  }
}
FieldTypeDescription
successfalseAlways false for errors
error.codestringMachine-readable error code
error.messagestringHuman-readable description

​
Status codes

StatusCodeMeaning
400BAD_REQUESTInvalid request parameters or body
401UNAUTHORIZEDMissing or invalid API key
403FORBIDDENValid key but insufficient scopes
404NOT_FOUNDResource doesn’t exist or isn’t accessible
429RATE_LIMITEDToo many requests — see Rate Limiting
500INTERNAL_ERRORUnexpected server error
For security, requesting a resource that exists but belongs to another organization returns 404 (not 403). This prevents ID enumeration attacks.

​
Handling errors

const response = await fetch('https://api.dronelist.io/v1/equipment/eq_abc123', {
  headers: { 'X-API-Key': 'dl_your_key_here' }
});

if (!response.ok) {
  const error = await response.json();

  switch (response.status) {
    case 401:
      // Invalid or expired API key
      throw new Error('Authentication failed');
    case 403:
      // Key lacks required scope
      throw new Error(`Insufficient permissions: ${error.error.message}`);
    case 404:
      // Resource not found
      return null;
    case 429:
      // Rate limited — retry after reset
      const resetAt = Number(response.headers.get('X-RateLimit-Reset'));
      // ... wait and retry
      break;
    default:
      throw new Error(`API error: ${error.error.message}`);
  }
}

const data = await response.json();

Tips

  • Always check success in the response body, not just the HTTP status
  • Log the full error response in production for debugging
  • Implement retries for 429 and 5xx errors with exponential backoff
  • Don’t retry 400, 401, 403, or 404 errors — they require code or configuration changes
