Source type: Public API specification directory
Access and cost
The directory states that its data can be accessed through an HTTP API and publishes the directory under a CC0 license; individual listed APIs retain their own availability, terms, and licensing.
Cost: Current price was not established in this review; check the provider's access terms.
Update cadence: Release cadence was not normalized in this review; check the source's dates, update notes, and API limits before comparing periods.
Before you use it
It is community-maintained: specifications can become stale or incomplete, and a directory entry does not establish that the listed API is free, stable, or commercially redistributable.
