How this service works
Public data API for SEBRA payments, PTP road accidents, Hearthstone cards, EU agri-food prices, and trade/market analytics. Paid data endpoints use x402 (USDC micropayments). Docs and discovery endpoints are free. 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
Returns a JSON object containing the geographic identifier, endpoint label, series code, and an array of time-stamped observations each with a period (e.g. '2024-01') and a numeric value representing the OECD indicator reading for that month.
Example use cases
Tracking US economic momentum
“Fetch the OECD composite leading indicator for the US using series code OECD_CLI_USA and show me the last 24 monthly observations so I can see how economic momentum has been trending.”
Country comparison for macro research
“Get the OECD leading indicator series for Germany — series code OECD_CLI_DEU — with up to 120 observations, so I can compare it against other eurozone countries in my macro research.”
Automated economic dashboard refresh
“Every morning, retrieve the latest OECD economic series data for Japan using series code OECD_CLI_JPN with the most recent 12 periods and add it to my dashboard tracker.”
Technical details
Endpoint
GEThttps://api.datanexusai.org/api/economic/oecd/series/%7Bseries_code%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured OECD time-series data (such as composite leading indicators or other OECD statistical series) by series code, and are willing to pay $0.01 USDC per call via x402 micropayment. Prefer this over scraping OECD's own website when you need clean JSON output ready for downstream analysis, or when integrating economic data into an automated agent workflow that requires programmatic access without managing API credentials beyond USDC payments.
Side effects
- Invalid or unknown series_code returns a 404 or empty observations array
- Exceeding rate limits or unpaid micropayment returns a 402 Payment Required response
- Network timeout or upstream OECD data unavailability may return a 503
- limit parameter outside acceptable range may be ignored or return an error
- Malformed path parameter (e.g. unencoded special characters) returns a 400 Bad Request
