Several projects track nostr resources. With this project under a permissive license we hope to get all Nostriches on board to build the most accurate and up to date repository of NOSTR projects to then embed that raw, machine-readable data in those projects.
nostr.info switched to using this resource as data source. You can study or straight copy from https://github.com/Giszmo/nostr.info to integrate in your own project. It's licensed MIT.
