Methods: client.UploadFile(), client.ListFiles(), client.RetrieveFile(), client.RetrieveFileContent().
Example
var client = new Phaseo(apiKey: apiKey);
var uploaded = await client.UploadFile(new Dictionary<string, object>
{
["purpose"] = "batch",
["file"] = "data:application/json;base64,eyJ0ZXN0Ijp0cnVlfQ=="
});
var file = await client.RetrieveFile("file_123");
var content = await client.RetrieveFileContent("file_123");
ListFiles() is wired through the SDK, but GET /files currently returns file_list_not_supported_with_shared_gateway_key
on the shared gateway key. Persist uploaded file ids and retrieve them directly instead.
