When a `group_1` user hist `structured-contents` API endpoint, he needs to be able to do `10k` API calls (like our currently available on-demand `articles` endpoint), so that he can easily test out the endpoint and see whether it's a fit for his product.
**Acceptance criteria**
As a `group_1` user I'm able to make `10k` API requests to `structured-contents` endpoint in a lifetime.
**ToDo**
- [ ] update access policies in the `main` API and infrastructure to allow access
- [ ] expand the same middleware that's applied to `/v2/articles` endpoint to `structured-contents` endpoint (we should be able to use the same `httputil.Cap` middleware)
- [ ] test it thoroughly in `dev` environment (you can reduce the threshold)
**Notes**
There's no need to do any UI changes or anything like that, as our `structured-contents` endpoint falls under On-demand API current dashboard visualization of requests left should do the job.
