Pricing & Quotas

Core model

• Signing is paid — every POST /v1/records call consumes 1 signature from your plan quota
• Verification is always free — POST /v1/verify and POST /v1/verify/batch never count against any quota
• No upfront integration fee — start on Free with no credit card

Quota enforcement

Free tier

When you reach 500 signatures/month, POST /v1/records returns 402:

{
  "error": "signature_limit_reached",
  "message": "Free tier limit of 500 signatures/month reached.",
  "upgrade_url": "https://certivu.ai/pricing",
  "limit": 500,
  "current": 500
}

Upgrade to any paid plan to continue signing.

Paid tiers

Paid plans never block. Signatures above the included allowance are counted as overage and charged at period end:

overage_bill = overage_count × overage_rate

Example: Starter plan, 5,400 signatures in a month:

• 5,000 included → $49/mo base
• 400 overage × $0.008 = $3.20
• Total: $52.20

---

Billing periods

• Monthly plans: 1-month rolling period, resets on the same day each month
• Annual plans: 12-month period from signup date

Usage is tracked in your org’s usage.signatures_this_period counter, which resets automatically at period end.
