Can HumDay connect to hashlookup CIRCL?

Yes. HumDay reads hashlookup CIRCL's own published API description and derives the operations from it, so there is no hand-built connector to wait for. 11 operations are documented.

Do I need to write code to automate hashlookup CIRCL?

No. You describe the outcome you want in plain words. HumDay agrees a contract with you, writes the program, and shows you a test run before anything touches your hashlookup CIRCL account.

What can HumDay do in hashlookup CIRCL?

2 of the 11 documented operations change something in hashlookup CIRCL, and 9 read from it. HumDay only ever uses the specific operations your approved contract needs.

Is my hashlookup CIRCL account safe?

Your credentials are stored encrypted and are never shown in chat, code, or logs. Every run is limited to the operations you explicitly approved, and anything that writes to hashlookup CIRCL is held behind that approval.

Automate hashlookup CIRCL

HumDay reads hashlookup CIRCL’s own published API description and derives 11 operations from it. Describe the outcome you want in plain words — you get a program that is written, proven on real data, and run for you.

What hashlookup CIRCL is

![](https://www.circl.lu/assets/images/circl-logo.png) [CIRCL hash lookup](https://hashlookup.circl.lu/) is a public API to lookup hash values against known database of files. For more details about all the datasets included [visit the website of the project](https://www.circl.lu/services/hashlookup/). The API is accessible via HTTP ReST API and the API is also [described as an OpenAPI](https://ha

GETReturn children from a given SHA1./children/{sha1}/{count}/{cursor}

How automating hashlookup CIRCL works

Describe the outcome. Say what you want to happen, in your own words. No node graphs, no field mapping.
Approve the contract. HumDay writes down exactly what it will do, what it will touch, and what it will never do. You approve it before anything is built.
See it proven. The program runs and shows you the result before it is allowed near your live hashlookup CIRCL account.
Grant access, then go live. You approve the specific hashlookup CIRCL operations it may use — and only those.
