Questions developers ask
What does APIDir verify about OpenAI API?
APIDir separates the service channel from the underlying model owner, records exact offer configuration, links the source, and exposes the check date.
Does an entry mean APIDir recommends this provider?
No. A directory record is a research starting point. Review current sources, legal terms, limits, and a workload-specific test.
Why can a displayed observation be stale?
Historical observations remain visible for audit, but stale records do not support current cheapest or savings claims.
