hey Hive account@ura-soul ,
Always happy to see people learn more about what's going on in HAF core work.
i've seen your work on ureka.social, pretty nice! Would be great to see some APIs integrated there.
APIs are publicly accessible, and they are shipped within Hive/HAF nodes, making them open source and decentralized.
The easiest way to get access to the APIs is via their swagger documentation, available on HAF nodes' URL.
For example, head over to https://api.syncad.com/ (has more recent tagged code) and you can see all different available APIs, you can switch by project to find different API sets.

Feel free to reach out on discord if you need any further assistance.
