Select Plan, if you want to try out the API we have added a Taster plan for $1 that will let you try out the various API end-points. Once you select a plan you will be routed to Stripe where you can complete your purchase and then you will be sent back to SimpleOptOutCompliance.com
Once you return to the Developer page you can see your API key, usage limits and subscription period. You can now copy the API key and try out the end points via the Swagger Interface here.
