Choosing well
Compare pricing models
Payment APIs use paid, freemium or request-a-quote pricing. Published notes include usage-based starting prices, monthly fees, per-user charges and €0/mo plans.
Check what the starting price covers before comparing providers. A free plan does not describe the cost of paid usage.
Check the free plan
Airwallex Payments and Mollie are marked with free plans in the list. Confirm the plan's limits and when paid charges begin before building around it.
Match your platforms
Platforms represented here include web, API, iOS, Android and browser extensions. Individual tools expose different combinations, so check the listing for the platform you need.
Stripe Payments lists Android, iOS and web support. GoCardless Bank Account Data and PayPal Checkout list API and web access.
Check the service scope
The category includes checkout services, bank-account data access and fraud-protection tools. Choose a service whose stated function matches your integration rather than assuming every payment API covers the same work.
