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 code, endpoint identifier, series code, and an array of observations each with a numeric value and period (year). For example: {geo: 'USA', endpoint: 'worldbank_series', series_code: 'WB_GDP_PER_CAPITA_USA', observations: [{value: 76329.6, period: '2022'}, ...]}
Example use cases
Country GDP trend analysis
“Pull me the last 40 years of World Bank GDP per capita observations for the USA — I want to see the trend over time.”
Development indicator research
“Get me the most recent World Bank data for the series code WB_POVERTY_HEADCOUNT for India, up to 30 observations, so I can analyze poverty trends.”
Cross-country economic comparison
“Fetch World Bank GDP growth series data for Germany using the series code WB_GDP_GROWTH_DEU, give me the last 25 observations for my economic comparison report.”
Technical details
Endpoint
GEThttps://api.datanexusai.org/api/economic/worldbank/series/%7Bseries_code%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, time-series macroeconomic data sourced from the World Bank, identified by a specific series code. It is ideal for economic research, trend analysis, country-level development statistics, and data enrichment workflows that require authoritative global economic indicators. Prefer it over generic web scraping or other data providers when you need clean, numeric, period-annotated World Bank observations via a pay-per-call micropayment model.
Side effects
- Invalid or unknown series_code returns 404 or empty observations array
- Exceeding API limits or missing USDC micropayment returns 402 Payment Required
- Malformed path parameter (e.g. un-encoded characters) causes 400 Bad Request
- World Bank upstream data unavailability may cause 503 or empty result
- Limit parameter out of accepted range may return a validation error
