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 a count of matching datasets and an array of dataset metadata objects, each with dataset_id, row_count, series_count, geo_count (number of geographies), period_min, and period_max (year range of coverage), plus an endpoint label.
Example use cases
Discover EU energy efficiency datasets
“What Eurostat energy datasets are available on DataNexusAI with the prefix 'nrg_ind'? Show me up to 100 and include how many rows and geographies each covers.”
Explore full energy dataset catalog
“Give me a list of all the energy datasets available through DataNexusAI so I can see which ones have data going back before 2010 and cover the most countries.”
Find ETS-related energy dataset IDs
“I'm looking for Eurostat energy datasets related to emissions trading — can you search DataNexusAI for datasets with 'ets' in the ID and tell me how many series each one has?”
Technical details
Endpoint
GEThttps://api.datanexusai.org/api/v1/energy/datasets?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover what Eurostat energy datasets are available before fetching actual data — ideal for building dataset pickers, checking coverage, or identifying dataset IDs to pass to downstream data query endpoints. Prefer this over general Eurostat APIs when you need quick filtered catalog access with per-call micropayment pricing and no subscription required.
Side effects
- Invalid or non-matching prefix filter returns empty dataset array with count 0
- Missing or invalid x402 USDC micropayment returns 402 Payment Required
- Limit parameter out of range may return error or be clamped to default
- Network timeout if Eurostat upstream is slow or unavailable
