you can paginate however you want. The default is the return 10. You can return an amount 1-100 and use the offset parameter to get the next X results.
Founder here. Returning total count is a very expensive action and most users don't use the result. Therefore, by returning paginated results you can allow the users that need that data, to loop through all the paginated pages and get the total count. It may add an extra step but for 98% of users the API will run faster.
Would happy to give you some test credits to validate our data source. Also we do offer tiered pricing, please feel free to contact me directly for more details.
We use data provided by local post offices from the country you specify. It was really hard to build, aggregate the data, and than standardize the input and output. Would appreciate any feedback you have on it.
Only way to judge is to test it out. Our data comes from the local post office of every country. We have street level address verification. Happy to give you some free credits to try it yourself just email me.
We offer it to a few customers who use it. Still trying to figure out the best way to offer it publicly. Happy to work with you if this is something you are looking to do. We definitely need more feedback on this one.
