Looking at the [PassiveTotal docs](https://api.passivetotal.org/api/docs/#api-Account-GetV2AccountQuotas), there's both `quota` and `quotas`. I've raised a ticket with them I think it should be `/account/quota` [here](https://github.com/westwardai/OpenSecurityAPIs/blob/508e209f781a668c5ede6a89ebd1eff609758926/data/PassiveTotal.yaml#L40), based on my testing, though I'll update this issue if they say otherwise.
