Rate Limits & Quotas

OTP Edge uses a tier-based quota system to ensure infrastructure stability and fair usage across all workspaces.

Quota Tiers

Your monthly request quota is determined by your subscription tier.

Tier	Monthly Quota	Features
7-Day Free Trial	10,000 requests	Edge routing, Basic Logs
Monthly	10,000 requests	Priority routing, Advanced Analytics
Annual	Unlimited	Dedicated infrastructure, SLA

If your workspace exceeds its monthly quota, the API will return a 429 Too Many Requests error.

{
  "error": "Usage quota exceeded. Please top up or upgrade.",
  "code": "QUOTA_EXCEEDED"
}

To resume service, you can either wait for your next billing cycle to reset or upgrade your tier in the Billing section of your dashboard.

To protect your account from malicious bots and “OTP bombing” attacks, we enforce a strict cooldown per recipient.

Recipient Cooldown: 60 seconds per phone number.
Max Verification Attempts: 5 failed verification attempts per OTP code before the code is permanently invalidated.
Error Response: 429 Too Many Requests with code SPAM_COOLDOWN.

These guardrails are active on all tiers to protect your workspace reputation and budget.
