Installation

pnpm add @hivepay/client

Quick Start

import { HivePay } from '@hivepay/client';

const hivepay = new HivePay({ apiKey: 'sk_live_xxx' });

// Create a payment
const payment = await hivepay.payments.create({
  amount: '10500',    // 10.500 HBD (precision 3)
  currency: 'HBD',
  description: 'Order #12345'
});

// Redirect user to checkout
window.location.href = payment.checkoutUrl;

For more examples and detailed documentation, see the High-level documentation.

API Reference

Creating a Client

import { HivePay } from '@hivepay/client';

const hivepay = new HivePay({
  endpoint: 'https://hivepay.me', // optional, default
  apiKey: 'sk_live_xxx',          // required for most operations
  timeout: 30000                  // optional, default 30s
});

// Create client without API key (for registration)
const publicClient = new HivePay();

Payments

Create a Payment

const payment = await hivepay.payments.create({
  amount: '10500',           // Amount in smallest unit (satoshis)
  currency: 'HBD',           // 'HIVE' or 'HBD'
  description: 'Order #123'  // Shown to customer
});

console.log(payment.id);          // Payment ID
console.log(payment.checkoutUrl); // URL to redirect customer
console.log(payment.fee);         // Fee amount
console.log(payment.net);         // Net amount you receive

Get Payment Details

const payment = await hivepay.payments.get('payment_id');

console.log(payment.status);           // 'pending', 'completed', 'cancelled', etc.
console.log(payment.amount.formatted); // '10.500 HBD'
console.log(payment.amount.usdCents);  // USD equivalent in cents
console.log(payment.expiresAt);        // Date object

Check Payment Status

const status = await hivepay.payments.getStatus('payment_id');

if (status === 'completed') {
  // Handle successful payment
}

Wait for Payment Completion

// Polls until payment reaches terminal status
const status = await hivepay.payments.waitFor('payment_id', {
  timeout: 300000,  // 5 minutes
  interval: 3000    // Check every 3 seconds
});

List Payments (Paginated)

// Get first page
const result = await hivepay.payments.list();
console.log(result.data);                  // Array of payments
console.log(result.pagination.page);       // Current page: 1
console.log(result.pagination.limit);      // Items per page: 20
console.log(result.pagination.total);      // Total items: e.g., 150
console.log(result.pagination.totalPages); // Total pages: e.g., 8

// Get specific page
const page3 = await hivepay.payments.list({ page: 3 });

// Custom page size (max: 100)
const largePage = await hivepay.payments.list({ page: 1, limit: 50 });

Iterate Through All Payments

// Direct iteration (uses default page size of 20)
for await (const payment of hivepay.payments) {
  console.log(payment.id, payment.status);
}

// With custom page size
for await (const payment of hivepay.payments.iterate({ pageSize: 50 })) {
  await processPayment(payment);
}

Get Current Fee Rate

const feePercent = await hivepay.payments.getFeeRate();
console.log(`Current fee: ${feePercent}%`); // e.g., "1.5%"

Merchants

Register a New Merchant

// No API key required for registration
const publicClient = new HivePay();

const result = await publicClient.merchants.register({
  name: 'My Store',
  iconUrl: 'https://example.com/logo.png',
  hiveAccount: 'mystore'
});

// IMPORTANT: Store the API key securely!
// It cannot be retrieved again.
console.log('API Key:', result.apiKey);
console.log('Merchant ID:', result.merchant.id);

// Create authenticated client with new API key
const authClient = publicClient.withApiKey(result.apiKey);

Get Current Merchant

const merchant = await hivepay.merchants.getCurrent();

console.log(merchant.name);
console.log(merchant.createdAt);
console.log(merchant.webhookUrl);

Get Merchant Details

const merchant = await hivepay.merchants.get('merchant_id');

console.log(merchant.name);
console.log(merchant.isActive);
console.log(merchant.hiveAccount);

Update Merchant Settings

const updated = await hivepay.merchants.update('merchant_id', {
  iconUrl: 'https://example.com/new-logo.png',
  webhookUrl: 'https://example.com/webhooks/hivepay',
  hiveAccount: 'newaccount'
});

x402 Protocol

HivePay operates an x402 facilitator that lets AI agents and automated clients pay for checkout sessions via the HTTP 402 protocol. The checkout URL returned by payments.create() works for both browsers and x402 clients — no additional setup needed.

See the x402 documentation for the full protocol details.

Toggle x402 Support

x402 is enabled by default for all merchants. Toggle it via the x402Enabled field:

// Disable x402 payments
await hivepay.merchants.update('merchant_id', { x402Enabled: false });

// Re-enable x402 payments
await hivepay.merchants.update('merchant_id', { x402Enabled: true });

// Check current status
const merchant = await hivepay.merchants.getCurrent();
console.log(merchant.x402Enabled); // true

Verify a Payment Payload

Validate an x402 payment against a session without broadcasting:

const result = await hivepay.payments.x402Verify('session_id', {
  x402Version: 1,
  scheme: 'exact',
  network: 'hive:mainnet',
  payload: {
    signedTransaction: tx,
    nonce: 'unique-nonce'
  }
});

if (result.isValid) {
  console.log('Valid payment from:', result.payer);
} else {
  console.log('Invalid:', result.invalidReason);
}

Settle a Payment

Verify, broadcast to the Hive blockchain, and mark the session as completed:

const result = await hivepay.payments.x402Settle('session_id', {
  x402Version: 1,
  scheme: 'exact',
  network: 'hive:mainnet',
  payload: {
    signedTransaction: tx,
    nonce: 'unique-nonce'
  }
});

if (result.success) {
  console.log('TX:', result.txId, 'Payer:', result.payer);
} else {
  console.log('Failed:', result.errorReason);
}

Admin Operations

Admin endpoints require an API key with admin privileges.

List Merchants (Paginated)

// Get first page
const result = await hivepay.admin.listMerchants();
console.log(result.data);                  // Array of merchants
console.log(result.pagination.page);       // Current page: 1
console.log(result.pagination.limit);      // Items per page: 20
console.log(result.pagination.total);      // Total items: e.g., 50
console.log(result.pagination.totalPages); // Total pages: e.g., 3

// Get specific page
const page2 = await hivepay.admin.listMerchants({ page: 2 });

// With search query and custom page size (max: 100)
const filtered = await hivepay.admin.listMerchants({
  page: 1,
  limit: 50,
  query: 'store'
});

Iterate Through All Merchants

// Iterate all merchants
for await (const merchant of hivepay.admin.iterateMerchants()) {
  console.log(merchant.id, merchant.name, merchant.isActive);
}

// With search query and custom page size
for await (const merchant of hivepay.admin.iterateMerchants({ query: 'store', pageSize: 50 })) {
  console.log(merchant.name);
}

Activate/Deactivate Merchant

// Activate a merchant
await hivepay.admin.setActive('merchant_id', true);

// Deactivate a merchant
await hivepay.admin.setActive('merchant_id', false);

Error Handling

The client throws HivePayError for all API errors:

import { HivePay, HivePayError, isHivePayError } from '@hivepay/client';

try {
  await hivepay.payments.get('invalid-id');
} catch (error) {
  if (isHivePayError(error)) {
    console.log(error.code);       // 'NOT_FOUND_ERROR'
    console.log(error.statusCode); // 404
    console.log(error.message);    // Error message

    // Type-safe error checking
    if (error.isNotFound()) {
      // Handle not found
    } else if (error.isAuthError()) {
      // Handle authentication error
    } else if (error.isValidation()) {
      // Handle validation error
    } else if (error.isRateLimited()) {
      // Handle rate limit
    }
  }
}

Error Codes

| Code | Description | | ------------------------ | ------------------------------------ | | NETWORK_ERROR | Network request failed or timed out | | API_ERROR | General API error | | AUTHENTICATION_ERROR | Invalid or missing API key (401) | | FORBIDDEN_ERROR | Insufficient permissions (403) | | NOT_FOUND_ERROR | Resource not found (404) | | VALIDATION_ERROR | Invalid request parameters (400) | | RATE_LIMIT_ERROR | Too many requests (429) | | SERVER_ERROR | Server error (5xx) |

Webhooks

HivePay sends webhooks for payment status changes. The client provides built-in verification using the Web Crypto API.

Important: Webhook verification requires a secure context (HTTPS or localhost). It will not work over plain HTTP in production.

import { HivePay } from '@hivepay/client';

const hivepay = new HivePay({ apiKey: 'sk_live_xxx' });

// In your webhook handler (e.g., Express, Hono, etc.)
async function handleWebhook(req: Request) {
  const result = await hivepay.verifyWebhook({
    payload: await req.text(),
    signature: req.headers.get('X-HivePay-Signature')!,
    timestamp: req.headers.get('X-HivePay-Timestamp')!,
    maxAge: 300000 // Optional: reject webhooks older than 5 minutes
  });

  if (!result.valid) {
    console.error('Webhook verification failed:', result.error);
    return new Response(result.error, { status: 401 });
  }

  const { event } = result;
  if (event.type === 'payment.status_changed') {
    const { paymentId, status } = event.data;
    console.log(`Payment ${paymentId} is now ${status}`);

    // Handle the status change
    if (status === 'completed') {
      await fulfillOrder(paymentId);
    }
  }

  return new Response('OK');
}

Testing Webhooks

For testing, you can create webhook signatures:

import { HivePay } from '@hivepay/client';

const hivepay = new HivePay({ apiKey: 'sk_test_xxx' });

// Create a test webhook
const { signature, timestamp, body } = await hivepay.createTestWebhook({
  type: 'payment.status_changed',
  data: { paymentId: 'pay_xxx', status: 'completed' }
});

// Use in test request
const response = await fetch('/webhooks/hivepay', {
  method: 'POST',
  headers: {
    'X-HivePay-Signature': signature,
    'X-HivePay-Timestamp': timestamp,
    'Content-Type': 'application/json'
  },
  body
});

Requirements

• Node.js 18.0.0 or later (for native fetch)
• TypeScript 5.6 or later (for development)
• Secure context for webhook verification (HTTPS or localhost)
