Third-party sources keep their own terms
Many datasets are built from public sources (for example the Bitcoin blockchain, mempool.space, GitHub, OpenStreetMap, fund issuers and exchanges). Each page and API response names its sources. Data taken from those sources stays under the source's own license or terms; for example OpenStreetMap data is under ODbL. Please credit the original source as well.
