How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON object containing the country name, indicator name (e.g. 'GDP (current US$)'), and an array of rows each with a date and numeric value — representing a time series of the requested economic indicator.
Example use cases
GDP comparison across countries
“Get me the GDP figures for the USA, Germany, and China so I can compare their economic sizes this year.”
Historical economic trend analysis
“Pull the historical GDP data for Brazil going back as far as available so I can chart its economic growth over time.”
Agent-driven macroeconomic monitoring
“Every week, fetch the latest economic indicators for Japan and alert me if GDP changes by more than 2% from the prior reading.”

Endpoint
GEThttps://anibalb.duckdns.org/x402/economic-indicators?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need macroeconomic indicator data (like GDP) for a specific country without account registration or API keys, and you can pay micro-amounts in USDC on Base via x402. Ideal for AI agents operating in a pay-per-call model needing one-off economic lookups.
Side effects
- Invalid or unsupported country code returns an error or empty rows array
- Unsupported indicator type returns no data
- Payment failure via x402 results in 402 response before data is delivered
- Network timeout on the duckdns.org dynamic host if server is offline
- Empty rows if data is not available for the requested period
