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 with the endpoint name ('energy_countries') and an array of country objects, each containing a two-letter geo code (e.g. 'BG') and a row_count indicating how many energy records exist for that country.
Example use cases
Discover energy data coverage before querying
“Before I start pulling energy stats, can you tell me which countries are available in the Eurostat energy dataset and roughly how much data each one has?”
Find country code for targeted energy lookup
“I want to query Bulgarian energy data — can you first check whether Bulgaria is in the energy countries list and what its country code is?”
Audit dataset completeness for EU energy report
“I'm building an EU energy report and need to know which countries have data in the Eurostat energy database — can you list all of them with their record counts?”
Technical details
Endpoint
GEThttps://api.datanexusai.org/api/v1/energy/countries?utm_source=zero.xyzWhen to prefer
Use this endpoint first when you need to discover which countries are available before making targeted energy data queries. It is ideal for building dynamic country selectors, validating country codes, or auditing dataset coverage before committing to deeper paid queries on country-specific energy data.
Side effects
- Invalid limit parameter (non-integer) returns a validation error
- Payment failure via x402 if USDC balance is insufficient — returns HTTP 402
- Empty result if dataset has no indexed countries yet
- Rate limiting or quota exceeded returns HTTP 429
