HELPERG Data

The infrastructure behind HELPERG's data products: a public JSON API that needs no credential, the official providers and licences it reads, whether each domain is operational, and how to integrate — for the economic calendar, published statistical values, official release notices and weather.

No forecast, consensus or rating

Looking for the data itself? Weather is in the Live data bar at the top of every page. The economic products are grouped below.

Economics

Economic data

Official-source economic data currently available through HELPERG.

Economic calendar: Scheduled official releases with the status the publisher states, verified values where published, and an official source on every row. Eurostat · ECB · U.S. BLS
Releases: Published statistical values with unit, reference period, publication status, the previous period and the revision history. Eurostat · ECB · U.S. BLS
Economic news: The publishers' own release notices, decisions and statements, linked to the calendar events and series they concern. U.S. BLS · Eurostat · ECB

Live

Is the data service operational?

Read from the public status route when this page loads: one of four honest words per data domain, when each last received data, and whether the corpus is held in durable storage. Unknown is reported as unknown.

Checking the public status endpoint…

This live reading needs JavaScript. The status is available as JSON at /api/public/v1/status and explained on the status page.

Integrate

The developer surfaces

What the platform reads, whether it is operational, and how to call it. Each of these is also a JSON endpoint.

Registered

Official providers and what is registered

Counts are derived from the platform's own registries at build time. Whether a series has published values on this deployment is stated per record by the API, never assumed here.

5
official organisations: Norwegian Meteorological Institute, U.S. Bureau of Labor Statistics, Eurostat, European Central Bank, Board of Governors of the Federal Reserve System

7
economics sources — release calendars and statistical datasets of Eurostat, the ECB and the U.S. BLS

68
registered release families with a publisher, a schedule source and, where published, the series they carry

32
registered statistical series with a fixed identity — country, frequency, unit, adjustment and transformation

4
official publication feeds — release notices, decisions and statements, linked to the calendar and series, never summarised

weather provider — the Norwegian Meteorological Institute, under CC BY 4.0

Every provider, its licence and the attribution it requires: sources page.

Two ways in, deliberately different

Public access — no credential: The pages on this site and the JSON endpoints under /api/public/v1/. Bounded windows and page sizes, shared-cacheable responses, explicit public record shapes, and every value with its source and licence. Meant for reading, for citing, and for server-side integration without an account.
Consumer access — credentialed: The endpoints under /api/v1/ serve HELPERG's own ecosystem products with a credential and a scope, wider windows, full canonical records and revision histories. They are not opened by anything on this site, and no page here carries a credential.

Both read the same corpus through the same services. The public layer maps records into smaller, allow-listed shapes; it does not re-derive any economic meaning.

Provenance and reliability

Authoritative sources only. Data is taken from the organisation that originates it — a statistical agency, a central bank, a meteorological institute — never from an aggregator, and commercial calendars are not consulted.
Validation at the boundary. Every provider payload is checked against a schema of that provider's shape before anything is read from it. What does not fit is quarantined, not guessed.
One truth model. A scheduled event, a published value, and a revision are three different records. A scheduled time that has passed never becomes a publication; a value is published only when an observation has been verified; a revision keeps the vintage it replaced.
Provenance on every record. Source, source URL, when HELPERG retrieved it, what the source said about its own change, and the licence it travels under. Where an official interface publishes the inputs and not the headline figure, HELPERG computes the figure the agency itself prints, in exact decimal arithmetic, and says so on the record with the inputs and the arithmetic.
Freshness stated, never hidden. Responses say whether the corpus is fresh, stale or unavailable, and the status page reports each domain in four honest words: ok, degraded, unavailable, unknown.

What this platform does not do

It publishes no forecast, consensus or estimate of any kind and rates nothing: HELPERG holds no survey of forecasters, and every value shown is either the publisher's own figure or a figure computed from the publisher's own inputs and marked as such. It does not scrape publishers, reproduce copyrighted articles, or redistribute data whose terms do not permit it. It does not fill a gap with an estimate: a value that has not been published is recorded as absent, and a value served from cache is served with its real age attached.
