Global Financial Information · Data API v1

Every number here carries a source and a date.

193 economic series across 39 countries, readable by a person, a spreadsheet or an AI assistant. No key, no sign-up. Each series returns its level, unit, as-of date, source status and a finished citation string. History depth, revision records, bulk export and the statutory rules layer are licensed.

One request

curl https://packersblacktemplars-sketch.github.io/gfi-api/api/v1/series/USA.POLICY.RATE.json

That returns the United States policy rate at 3.88 percent as of 2026-11-03, sourced to the BIS compilation of central bank policy rates, with the citation string already assembled: the subject, the series id, the as-of date, the retrieval date and a permanent URL.

Routes

File	Returns
index.json	Counts, data as of, the tier, and this endpoint map.
catalog.json	All 193 series in one file: id, subject, value, unit, as-of, source status, coverage tier, definition and citation.
series/{series_id}.json	One series in full: latest, prior, change, history window, definition, source, citation.
country/{iso3}.json	A country packet: standing state, shifts, rules, people, places, news, sources and its own citation.
changes.json	Verified shift rows only. Today it returns an empty set declared as not_collected, not a set of zeroes.
openapi.json	The contract, for tooling and agents.

Two hosts, same bytes. This page and every route above serve application/json. The branded base on Hugging Face is the one to cite; that host serves every JSON file as text/plain, so point a strict client at this host instead.

Series id grammar

GEO.FAMILY.MEASURE, uppercase, dots, issued once and never reused. GEO is ISO3. Families are POLICY (RATE, REAL), PRICE (CPI_YOY), FISCAL (DEBT_GDP), MACRO (GDP_GROWTH), DEMO (six population and labour measures) and, on the licensed tier, RULE (eight statutory limits).

Four rules the data follows

1. A source is named only when that source carries the figure. Where it does not, the source is null and the status says unresolved. 0 of 193 series are in that state today rather than borrowing a neighbour's name.
2. Annual figures are periods, not dates. The as-of field is null, the period is the year and an estimate flag travels with it. No figure is stamped December 31 to make a column look tidy.
3. A derived figure publishes its inputs and a verdict on comparability. The real policy rate carries the date of the rate and the period of the price index it was deflated by. 3 series are flagged for review, including the United States, whose real rate still rests on 2024 inflation.
4. Empty is declared. An uncollected block says so. It never renders as a blank cell or a zero.

How to cite

Global Financial Information, “United States policy rate” (USA.POLICY.RATE), data as of 2026-11-03, retrieved 2026-11-10.

The string that arrives in the response already includes the permanent URL for that series, so a citation written today still resolves after the next release.
