API support for querying an ecosystem and change log support

[zhenghao104]

Currently there is no API to query all vulnerabilities for an ecosystem similar to the filtering here https://osv.dev/list?ecosystem=GIT

Is there any plan to support it?

Also, is there any way to check what has changed in the database for each ecosystem or package version since a timestamp?

I am aware of https://google.github.io/osv.dev/data/ but it requires downloading and unzipping a file. We are trying to build a system to cache all the Git vulnerabilities, and I haven't found a way to refresh our database periodically without downloading and unzipping the file every 24 hours. There's also no API to check what has changed so we need to reingest everything once in a while.
