LevelBlue Open Threat Exchange OTX

OTX aggregates ongoing community submissions and provider analysis without a stated geographic boundary or history start. The current API requires authentication on checked pulse endpoints; LevelBlue's published API article states 10,000 requests per hour with a key, but that article dates to 2017.
