How this service works
Public data API for SEBRA payments, PTP road accidents, EU agri-food prices, Eurostat energy (+ ETS), and trade/market analytics. Paid data endpoints use x402 (USDC micropayments). HTML docs at `/api/` are free and are intentionally omitted from this OpenAPI document so discovery scanners do not probe them as paid resources. Machine-readable discovery: `https://api.datanexusai.org/openapi.json`, `https://api.datanexusai.org/llms.txt`, `https://api.datanexusai.org/.well-known/x402`. Human docs: `/docs` and `/api/`.
Output
A JSON object containing an endpoint label and an array of registry records, each with a registry code, count of registered installations, and the sum of verified emissions for that registry. Filterable by year and/or country code, paginated by a limit parameter.
Example use cases
EU carbon emissions compliance research
“Pull up the EU ETS summary for 2022, filtered to the DE registry, with up to 50 results — I need installation counts and verified emissions to assess Germany's compliance posture.”
Cross-country ETS comparison for ESG report
“Get me ETS summary data for 2021 across all available registries, up to 30 results, so I can compare verified emissions totals between EU member states for our ESG report.”
Monitoring Bulgarian ETS registry
“What does the EU Emissions Trading System summary look like for Bulgaria — BG registry — for 2023? I need installation counts and verified emissions figures.”
Technical details
Endpoint
GEThttps://api.datanexusai.org/api/v1/energy/ets/summary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need aggregated EU ETS statistics — installation counts and verified emissions — broken down by registry (country), optionally for a specific year. It is ideal for ESG analysis, climate policy research, and carbon market monitoring. Prefer it over raw Eurostat data sources when you need a clean, pre-aggregated JSON summary accessible via micropayment without manual ETL.

- Year out of available data range returns empty results
