Choosing the Right Solution
The Chainalysis Sanctions API is a RESTful API that returns information for all crypto addresses on the SDN list.
It's essential to understand the differences between the Sanctions API and the Sanctions Screening oracle, which checks only against sanctioned Ethereum/EVM addresses.
The API also provides additional information from OFAC, including a property's name, description, and URL, which can be valuable in making informed decisions.
This information can help you decide which solution is right for your company, taking into account your specific needs and requirements.
Incorrect API Key
Using an incorrect API key can cause a lot of trouble. This can lead to your application being blocked or even shut down by the API provider.

If you're using a public API, you might be using an incorrect key without even realizing it. This can happen if you copied the key incorrectly or if it's expired.
Make sure to double-check your API key in your code. This can save you a lot of time and frustration in the long run.
API keys are usually provided by the API provider, and they can be very sensitive information. It's essential to keep them secure to avoid any issues.
Having a backup plan in place can also help. This can include having a valid API key ready to go or having a different solution in place.
Which Solution Is Right for My Company?
Choosing the right solution for your company can be a daunting task, especially when it comes to complex issues like sanctions and regulatory compliance.
