See which plans include a specific API on its page in Tools.
Each request to an APIStack API counts as one call. Your monthly quota is shared across every API your plan includes.
Requests return HTTP 429 until your quota resets each month. You can upgrade anytime, and Pro and Enterprise plans can buy top-ups. We email you at 80% and 100%.
Yes. Upgrades take effect immediately. Downgrades, cancellation, invoices and card changes are handled in the billing portal, reachable from your dashboard.
Most utility, data, web and finance APIs are on every plan. AI text tools need Pro or Enterprise, and some are Enterprise only. Each API page shows which plans include it.
Payments are processed securely by Stripe. We never see or store your card details.
Not a contractual one. Every API is health-checked automatically each day and we are alerted immediately when a check fails.
Start on Free and watch your usage in the dashboard. Upgrading takes a minute and your API key stays the same.
