Fiuvi150+ data sources, one endpoint: how we think about coverage
Coverage is the metric that matters most for a data API. Here is how we decide which sources to add next, and how we keep 99% of records resolving.
Coverage is deceptively easy to claim and hard to actually deliver. It is not enough to index a source once — new records appear daily, pages get restructured constantly, and metadata changes as sites redesign or migrate.
We prioritize new sources based on where activity is actually happening: high-traffic sites with growing content volume, APIs with active developer communities, and any data provider that starts seeing meaningful demand.
Once a source is added, the harder work is keeping it current. That is why 99% of records in our directory resolve with verified data and metadata at any given time — coverage is a maintenance problem as much as an integration one.
The result for developers is simple: you should not have to know or care which sources we support before you make a call. If the record exists, it should resolve.
