APIs & data.
Explore the engineering of a browser that depends on a public data provider. Read about unit conversions, validated identifiers, safe rendering, pagination, source labels, and failure states, without treating a third-party observation as independent chain validation.
Treat the source as a dependency
A public API has its own indexing, units, limits, and browser-access rules. Label those dependencies, keep remote values out of executable markup, and test failure states without shipping demonstration transactions as live records.
