How this service works
Annual consumer-price inflation (CPI, % change) per country from the World Bank keyless API (indicator FP.CPI.TOTL.ZG). Serves autonomous macro and monetary-policy agents, agent-to-agent inflation-comparison pipelines, and treasury bots pricing real returns across global economies. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
Returns a JSON object with an 'ok' flag, a year-keyed dictionary of annual CPI inflation percentages (e.g. {"2022": 8.00}), the country code, the World Bank indicator ID (FP.CPI.TOTL.ZG), the data source label, and the provenance URL pointing to the underlying World Bank API call used.
Example use cases
Real return pricing for treasury bot
“Get me the annual consumer price inflation figures for the United States from 2018 to 2023 using the World Bank CPI indicator, so I can calculate real yields on my bond portfolio.”
Emerging market inflation comparison
“Fetch the World Bank annual CPI inflation data for Brazil, India, and South Africa for 2020 through 2023 — I need to compare how inflation evolved across these emerging markets.”
Monetary policy macro research
“What was Germany's annual inflation rate from 2015 to 2023 according to the World Bank CPI indicator? I'm building a report on ECB monetary policy effectiveness.”
Technical details
Endpoint
POSThttps://worldbank-inflation-cpi-annual.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need structured, year-by-year CPI inflation data from the authoritative World Bank source for one or more countries, especially in autonomous macro-agent pipelines, agent-to-agent inflation-comparison workflows, or treasury bots calculating real returns — and when you want a simple POST interface with a $0.001 USDC micropayment rather than managing World Bank API quotas directly.
Side effects
- Invalid or unrecognized country code returns an error or empty data set
- Date range outside available World Bank data yields no results
- Malformed date string causes a parsing error
- World Bank upstream API unavailability may cause timeout or null result
- Indicator code other than FP.CPI.TOTL.ZG may not be supported by this wrapper
