How Narwhal handles data

Where the data comes from, what we check, and what we publish.

The rules differ by data type. Each API has its own methodology and limits.

Sources

Economics comes from government statistics offices and other official publishers. The coverage table names them.

FX comes from licensed or approved providers. Commercial provider names stay private unless attribution is required.

Palmoil uses official FFB schedules.

Before publication

Match the source, dataset, release, and period.
Check fields, units, timestamps, and completeness.
Normalize formats without filling missing values.
Store the accepted observation and its evidence.

Bad source data does not replace the last accepted result. Missing values stay missing.

Public and private

Public

Source institution or source class, units, periods, timestamps, calculations, revisions, and known limits.

Private

Credentials, private URLs, provider IDs, routing, contracts, internal schemas, and monitoring details.
