Billing & Pricing

PacSpace uses a monthly subscription model based on Verified Deltas. Each plan includes a set number of verified deltas per month. You're only charged for items that complete verification — failed or rejected items don't count.

Plans#

New accounts start on the Free plan with 100 verified deltas (lifetime cap) in the Sandbox environment. Upgrade to a paid plan to unlock Production access and higher volumes. Contact sales@pacspace.io for Enterprise pricing.

Free Plan Limits#

The Free plan is designed for evaluating the PacSpace API:

• 100 verified deltas (lifetime cap) — once exhausted, write operations return 402 Payment Required
• Sandbox only — Production environments require a paid plan
• No overage billing — the limit is hard-capped; upgrade to continue
• Reads, balance queries, and verification calls are always free

How Billing Works#

1. Count on Verify#

Deltas are counted when verification completes — not when you submit the request. This means:

• Queued items — no charge yet
• Processing items — usage reserved (held temporarily)
• Verified items — counted toward your monthly allotment
• Failed items — reserved usage released (no charge)

2. Monthly Subscription#

Each period runs for one calendar month. Your plan's monthly price covers the included delta allotment. At the end of each period:

• Usage is tallied against your plan's included deltas
• Overages are charged at your plan's overage rate
• Usage counters reset for the next month

3. Overage Billing#

If you exceed your plan's included deltas, additional deltas are billed at the overage rate:

Example: On the Starter plan ($3,000/month), if you verify 130,000 deltas in a month:

• 100,000 included in plan
• 30,000 overage × $0.012 = $360 overage charge
• Total: $3,360

Subscription Management#

All paid plans (Pilot through Scale) are self-service — subscribe, upgrade, downgrade, and cancel directly from the PacSpace dashboard. Enterprise plans are sales-led; contact sales@pacspace.io.

Subscribe#

Choose a plan from the Billing page in your dashboard. You'll be redirected to a secure Stripe Checkout to enter payment details. Once payment is confirmed, your new plan is activated immediately — there's no waiting period.

Change Plans (Upgrade or Downgrade)#

Both upgrades and downgrades take effect immediately:

• Proration — Stripe prorates the subscription charge. On an upgrade you're charged the difference for the remainder of the cycle; on a downgrade you receive a credit toward your next invoice.
• Usage does not reset — your consumed deltas for the current month carry over to the new plan. If a downgrade puts you over the new allotment, the excess is counted as overage at the new tier's overage rate right away.
• Upgrade absorbs prior usage — if you upgrade to a higher allotment, prior usage is absorbed and any overage from the old plan may drop to zero.

Example — mid-cycle downgrade:

1. Growth plan (500,000 allotment), 400,000 deltas consumed so far
2. Downgrade to Starter (100,000 allotment)
3. 300,000 deltas are now overage at the Starter rate of $0.012/delta
4. Any additional deltas this month are also billed at $0.012/delta
5. At the next period, usage resets and the Starter allotment of 100,000 applies

Cancel Subscription#

Cancellation schedules the end of your subscription at the current period end. Your paid plan access continues until that date, then your account reverts to the Free tier. Usage already consumed is still invoiced (including any overages).

Overage Invoicing#

Overages are invoiced as a separate Stripe invoice at the beginning of the following month. The invoice is auto-charged to the payment method on file. You can view all invoices in the Stripe Customer Portal, accessible from the Billing page.

Payment Failures#

If a payment fails, your plan status changes to past due. Stripe retries the charge automatically over several days. Your API access continues during the retry period. If all retries fail, the subscription may be cancelled by Stripe and your account will revert to the Free tier.

Monitoring Usage#

Via API#

Check your current plan:

curl https://balance-api.pacspace.io/dashboard/billing/plan \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"

{
  "statusCode": 200,
  "data": {
    "tier": "starter",
    "monthlyAllotment": 100000,
    "planPriceUsd": 3000,
    "overagePriceUsd": 0.012
  }
}

Check your monthly usage:

curl https://balance-api.pacspace.io/dashboard/billing/usage \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"

{
  "statusCode": 200,
  "data": {
    "period": "2026-02",
    "consumedDeltas": 1042,
    "overageCount": 0,
    "overageChargesUsd": 0,
    "remainingDeltas": 98958
  }
}

See Billing & Usage for full endpoint documentation.

Via Webhooks#

Each delta.verified webhook event includes usage data when available:

{
  "event": "delta.verified",
  "data": {
    "usage": {
      "plan": "growth",
      "includedDeltas": 500000,
      "consumedDeltas": 1042,
      "remainingDeltas": 498958,
      "overageRate": "$0.010/delta"
    }
  }
}

Set up a webhook endpoint to track consumption in real time.

What Counts as a Delta#

FAQ#

When am I charged? Only when a delta is successfully verified. Submissions that fail or are still processing don't incur charges.

Can I change plans mid-month? Yes. Both upgrades and downgrades take effect immediately with proration. Your usage does not reset mid-cycle — consumed deltas carry over to the new plan's allotment. See Subscription Management for details.

What happens if I hit my limit? On the Free plan, write operations return 402 Payment Required once the 100-delta lifetime limit is reached. Reads continue to work. Upgrade to a paid plan to unlock higher volumes. On paid plans, overages are billed at your plan's per-delta rate at the end of each period.

Are sandbox operations free? Yes. Sandbox usage does not count toward your plan allotment.
