Dart grammar checker quickstart

Send text to the edits endpoint. Sapling returns suggested replacements with character offsets so your application can review or apply each correction.

No language-specific SDK is required. The example uses a standard or commonly used HTTP client to call Sapling's JSON API.
Dart /api/v1/edits
void main() async {
  final response = await http.post(
    Uri.parse('https://api.sapling.ai/api/v1/edits'),
    headers: {
      'Content-Type': 'application/json; charset=UTF-8',
    },
    body: jsonEncode({
      'key': 'API_KEY',
      'text': 'Lets get started!',
      'session_id': 'Test Document UUID',
    }),
  );

  print(jsonDecode(response.body));
}
Example response application/json
{
  "edits": [
    {
      "start": 0,
      "end": 4,
      "replacement": "Let's",
      "sentence": "Lets get started!",
      "error_type": "R:OTHER"
    }
  ]
}

Each edit identifies the source range and replacement text. Preserve the original offsets when applying more than one edit.
