What is SENS
SENS Energy Data API provides programmatic access to the Polish electricity market: distribution system operator (DSO/OSD) tariffs, retailer offers, and composite price comparisons (distribution + supply + market components), calculated server-side from data derived from URE-approved tariff filings.
Instead of manually parsing price lists and tariff documents published by each individual operator, you send a single REST request and get back a normalized JSON response.
Who it's for
SENS is built for B2B integrators, not end consumers:
- Aggregators and comparison platforms that need up-to-date tariffs and prices in one consistent format,
- Retailers (sprzedawcy) who want to automate pricing for business customers,
- VPP / DSR operators and consumption-optimization companies that need structured market data,
- AI agents and LLM tooling that need a reliable source of truth for the Polish energy market (see the MCP integration).
