PipeProwler surveils the pipelines and corridors that move Henry Hub prices, including every active Gulf Coast LNG export corridor, in real time. Notice text and scheduled-quantity flows are ingested continuously, standardized into a unified topology of pipeline meters and hub tags, and resolved into severity-graded events at sub-minute latency. Every observation carries full data lineage from the raw source through to the API, which means a trader, a risk team, and an audit team are all looking at the same defensible record of what happened, when, and why it mattered.
