Billing calls consume no directory credits and operate on the account associated with your API key.
  • Usage: plan, monthly/purchased balances and UTC period dates.
  • History: daily and per-feature credit consumption.
  • Plans: unauthenticated live pricing catalog.
  • Plan checkout: hosted subscription payment link.
  • Credit checkout: hosted one-time credit purchase.
  • Portal: payment methods, invoices and cancellation.
Monthly credits refill on the first of each calendar month UTC; unused monthly credits do not accumulate. Purchased top-ups never expire and are spent after monthly credits. credits_remaining includes both balances. Keys for the same account share that balance. Checkout returns a payment URL, not a completed purchase. Open it and complete payment there. Plan changes and credits follow payment confirmation; check usage afterward. HTTP 200 from checkout creation is not payment success. Never send card data in these REST requests. Current checkout catalog: Pro $20/month for 10,000 credits, Growth $49/month for 100,000, Scale $199/month for 500,000; one-time packs $25 for 10,000. Prices and account allowances can change: read the live plans, checkout response and account usage instead of hardcoding. Checkout credit figures come from the checkout catalog; live account allowances may differ.
