Understanding FortiBlox Nexus billing, payment methods, and subscription management

Billing & Payments Overview

FortiBlox Nexus offers flexible billing options to suit your needs, whether you're an individual developer, growing startup, or enterprise organization.

How Billing Works

FortiBlox Nexus uses a credit-based subscription model with monthly billing cycles:

Subscribe to a tier based on your API usage needs
Receive monthly credits that reset at the start of each billing cycle
Credits are consumed with each API request (1 credit = 1 request)
Automatic renewal at the end of each billing cycle
Overage handling: Requests are throttled when credits are exhausted

Billing Cycle

Start: The day you subscribe (or upgrade/downgrade)
Duration: 30 days from subscription start
Credit Reset: Automatic at the start of each new cycle
Renewal: Automatic charge to your payment method

Understanding Credits

What is a Credit?

A credit represents one API request to FortiBlox Nexus services.

1 Credit = 1 API Request

Credit Consumption Examples

// Each of these consumes 1 credit:
await fetch('https://nexus.fortiblox.com/api/rpc/getBalance', {
  method: 'POST',
  body: JSON.stringify({ address: 'x1abc...' })
});
// ✓ 1 credit used

await fetch('https://nexus.fortiblox.com/api/rpc/getTransaction', {
  method: 'POST',
  body: JSON.stringify({ signature: 'sig123...' })
});
// ✓ 1 credit used

// Batch requests consume credits per inner request
await fetch('https://nexus.fortiblox.com/api/rpc/batch', {
  method: 'POST',
  body: JSON.stringify([
    { method: 'getBalance', params: ['addr1'] },
    { method: 'getBalance', params: ['addr2'] },
    { method: 'getBalance', params: ['addr3'] }
  ])
});
// ✓ 3 credits used (one per request in batch)

Credit Reset Schedule

Credits reset automatically at the start of each billing cycle:

Subscribe: Dec 1, 2025 at 3:00 PM UTC
First Reset: Jan 1, 2026 at 3:00 PM UTC
Second Reset: Feb 1, 2026 at 3:00 PM UTC
...and so on

Monitoring Credit Usage

Check your current credit usage anytime:

// Get current usage via API
const response = await fetch('https://nexus.fortiblox.com/api/usage', {
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY'
  }
});

const usage = await response.json();
console.log(usage);
// {
//   tier: 'developer',
//   credits_used: 12500000,
//   credits_total: 50000000,
//   credits_remaining: 37500000,
//   reset_date: '2026-01-01T15:00:00Z'
// }

Or view in the Developer Portal:

Dashboard → Usage → Current Period

What Happens When Credits Run Out?

When you exhaust your monthly credits:

Free Tier

Throttled to 10 requests/second
Error response: 429 Too Many Requests
Credits reset at next billing cycle

Paid Tiers (Developer/Business/Professional)

Throttled to Free tier rate (100 RPS)
Email notification sent
Recommendation to upgrade tier
Credits reset at next billing cycle

No overage charges - Your API access is throttled, not blocked.

Handling Credit Exhaustion

// Proper error handling for credit exhaustion
try {
  const response = await fetch('https://nexus.fortiblox.com/api/rpc/getBalance', {
    method: 'POST',
    headers: {
      'Authorization': 'Bearer YOUR_API_KEY',
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ address: 'x1abc...' })
  });

  if (response.status === 429) {
    const error = await response.json();

    if (error.code === 'CREDITS_EXHAUSTED') {
      // Credits exhausted - queue request or upgrade tier
      console.error('Monthly credits exhausted. Consider upgrading your tier.');
      // Implement retry logic or queue for next billing cycle
    } else {
      // Rate limit hit - implement backoff
      console.error('Rate limit exceeded. Implement exponential backoff.');
    }
  }
} catch (error) {
  console.error('Request failed:', error);
}
