Every datapoint, traced to its publisher.
The authoritative catalog behind Dynamic Feed: every upstream source, its licence, whether commercial use and redistribution are permitted, how often it updates, and the tools it backs. Each live value carries a per-row provenance + freshness envelope, so you can cite the source and verify your usage rights yourself.
Every source below is cleared for commercial redistribution and served with attribution per its licence. Sources whose terms don't permit it are paused entirely until licensed, they don't appear here at all. We'd rather serve fewer feeds than ones we can't stand behind.

Every datapoint is provenance-stamped and signed. Trace any subject's chain of custody with POST /v1/explain, or verify a signature against the public keys.
