flutter pub add voyant_apis

🚀 Quick Start

import 'package:voyant_apis/voyant_apis.dart';

🔐 Setup Credentials

final credentials = VoyantAccountCredentials(
  apiKey: "YOUR_API_KEY",
  accountId: "YOUR_ACCOUNT_ID",
  apiSecret: "YOUR_API_SECRET",
);

🌐 IP Intelligence

final ipIntel = VoyantApiIpIntelClient(
  credentials: credentials,
  projectId: "YOUR_PROJECT_ID",
);

// Single
final res1 = await ipIntel.lookup("8.8.8.8");

// Batch, max 50 ips
final res2 = await ipIntel.lookupBatch([
  "8.8.8.8",
  "1.1.1.1",
]);

🧠 Text Analysis

final text = VoyantApiTextAnalyzeClient(
  credentials: credentials,
  projectId: "YOUR_PROJECT_ID",
);

// Single
final res1 = await text.analyze("hello world");

// Batch
final res2 = await text.analyzeBatch([
  "hello",
  "world",
]);

🖼️ NSFW Detection

final nsfw = VoyantApiNsfwClient(
  credentials: credentials,
  projectId: "YOUR_PROJECT_ID",
);

// Read file as bytes
final bytes = await file.readAsBytes();

// Single
final res1 = await nsfw.analyze(bytes);

// Batch
final res2 = await nsfw.analyzeBatch([
  bytes1,
  bytes2,
]);

✉️ Email API

final email = VoyantApiEmailClient(
  credentials: credentials,
  projectId: "YOUR_PROJECT_ID",
);

Verification Email

final verification = EmailVerificationData(
  to: "user@example.com",
  fromType: EmailFromType.verify,
  username: "John",
);

final response = await email.send(verification.toJson());
// For verify
response.verifyOTP(otpController.text)

Welcome Email

final welcome = EmailWelcomeData(
  to: "user@example.com",
  fromType: EmailFromType.updates,
  appName: "Voyant",
  button: EmailButton(
    text: "Get Started",
    url: "https://voyantnetworks.com",
  ),
);

await email.send(welcome.toJson());

Custom Email

final custom = EmailCustomData(
  to: "user@example.com",
  fromType: EmailFromType.support,
  greeting: "Hello",
  title: "Welcome!",
  subtitle: "Glad to have you",
  message: "This is a custom email",
  subject: "Test Email",
);

await email.send(custom.toJson());

⚙️ Config

  • credentials → contains apiKey, accountId, apiSecret
  • projectId → API instance ID
  • accountId → your account identifier (required)

📌 Notes

  • NSFW: max 5 images, recommended <200KB each
  • Email: schema-based templates
  • All requests are securely signed (HMAC SHA256)

⚠️ Security

Do NOT expose apiSecret in production apps.
Use your backend to sign requests for public apps.
