Analytics that go beyond raw prices

Ultra and Mega plans unlock derived intelligence built on years of market telemetry.

Negative Price Risk

Know roughly 12 hours ahead when wholesale prices might go negative. Critical for battery operators and flexible demand.

Zone Correlation

Discover which markets move together. Sample DE ↔ FR linkage around 0.847 — essential context for coupled portfolios.

Carbon-Optimal Windows

Find the lowest-carbon contiguous hours ahead of any deadline — illustrative savings up to 42% versus peak hours for flexible loads.

Pricing

Four public plans —basic,pro,ultra, andmega— mirror RapidAPI quotas. Send X-RapidAPI-Subscription as BASIC, PRO, ULTRA, or MEGA and the gateway unlocks matching capabilities automatically.
