Dear [@OpenSanctions](https://discuss.opensanctions.org/groups/opensanctions)

We’re looking to set up an automated process to regularly check for any crypto related new sanctions data added to your platform. Could you please advise on the best way to do this? Specifically:

Is your data labeled by date so we can easily identify crypto related new entries?  
Is there an API or other method we can use to programmatically access the data on a regular cadence?  
Any other guidance you can provide on the most efficient way for us to stay up-to-date with your crypto related sanctions listings?

Hi there!

Here’s a few pointers:

- Our database includes some sanctioned wallets (addresses), often designated by the US and Israeli governments. (see [here](https://www.opensanctions.org/search/?schema=CryptoWallet)). If you are only trying to screen addresses, you could just [fetch that listing via our API](https://www.opensanctions.org/docs/api/search/) every N hours and see if anything is added. The `/search` API also accepts a `changed_since` parameter that you can use to skip all the old entries.
- If you also need to screen the names/identities of wallet holders (people, companies), that’s a more generic sanctions screening problem - check out [our matching guide](https://www.opensanctions.org/docs/api/matching/). Again, `changed_since` is supported to skip screening results you’ve already processed.

I hope this provides a few starting points! Please let us know if you have more questions 🙂

Best,

- Friedrich
