We currently offer three API versions: v1, v2, and v3.
v3
The v3 API is a RESTful API and it’s our latest API version, where we aim to gradually port over all other API calls from v1/v2.
The v3 documentation can be found here:
Limits
Limits for the v3 API are per user per API call per minute. With every API call performed, you can see the limits in the headers as explained here:
These limits are currently the same for all of our users. However, for our Enterprise customers we can adjust the limits to fit their needs.
v1/v2
Our v1/v2 APIs are non-RESTful APIs, which have been developed earlier on during the lifetime of our platform.
You can find all of these APIs in our API Explorer:
Limits
The limits for v1/v2 APIs are per user per month, and they are specific for each free/paid plan that you are currently on.
You can view each plan’s limits on our pricing pages:
If you need higher v1/v2 monthly limits, we can accommodate this on a case-by-case request; be sure to reach out to our support and explain your use case.
Exceptions
The only exceptions from the v1/v2 monthly API calls limits explained above are the Blacklist Check APIs:
The Blacklist Check APIs don’t consume v1/v2 monthly API calls; they function on a credits-based system, as explained here:
