cpi_inflation_yoy means the same thing in
Turkey as in Japan, which is what makes a cross-country query a single request rather
than a mapping exercise.

A country panel
One call returns the current reading of every indicator held for a country. This is the request behind a dashboard, and it replaces the per-metric fan-out that most people reach for first.One panel call is dramatically faster than one call per indicator, and it is what the
endpoint is built for. From a browser it also avoids a CORS preflight per metric.
One series, with history
One indicator, every country
Drop the country filter to get a cross-section: the same indicator for every country that publishes it.Things that will bite
Units differ by country for the same indicator. Payrolls arrive inthousands from
one office and persons from another. Read unit on every row and never pool across
units. See Units and periods.
Not every country has every indicator. Ask rather than probe:
/countries/{iso}/available-indicators is authoritative, and an empty response is an
answer, not a failure.
Some collections have ceased. collectionStatus: "ceased" means the publisher
retired the series permanently. It will not resume, and carrying its last value forward
as current is the quiet way to get a wrong answer for years.
Annual fallbacks are marked. A country whose only coverage is fallbackOnly has no
live national source. The row is real World Bank data and the wrong thing to score.
Trust metadata
The flags that decide whether a row belongs in a model.
Data availability
How deep coverage actually goes, per tier.
