利用規約
The interface is open and unauthenticated. Please keep request rates reasonable — everything is cached for two minutes, so polling faster than that returns the same bytes. Attribute figures to the provider named in the meta.attribution string, keep the reference period with any figure you republish, and do not present these values as live prices. Redistributing the underlying data as a substitute product is not permitted; see the Terms of Use.
