# act: keep proxy
a proxy: its name, the facet kind it stands for, its scope, its rule as a predicate, its strength, its named control, its failure mode, and whether it is aggregate-only to the proxy with its version by hash, not ready until its controls have run and its calibration is read
[figure: The caller sends KeepProxyInput to /v1/act/keep_proxy. The platform returns a card whose body is Proxy.]
POST/v1/act/keep_proxy
Keep a proxy. The call needs the strategy rung under a token with the act grant, and it is served by either, by the size bound.
The route takes [KeepProxyInput](/concepts/keepproxyinput) and returns a card whose body is [Proxy](/concepts/proxy).
## Request body
The request body is [KeepProxyInput](/concepts/keepproxyinput).
| field | type | required | note |
|---|---|---|---|
| `proxy` | [Proxy](/concepts/proxy) | yes | |
## Response
The route returns a card whose body is [Proxy](/concepts/proxy). Every card ends with a foot that states the basis of each number, the scope of the call, and the time when the facts were true.
## Headers
| header | required | meaning |
|---|---|---|
| `Scale-Scope` | yes | the scope the call runs in: tenant/, then /brand/, then /strategy/ |
| `Scale-As-True-On` | no | the date the facts must have been true on; defaults to now |
| `Scale-As-Known-On` | no | the date the facts must have been known on; defaults to now |
| `Scale-Key` | no | for a change, the key made from the input; a repeat under the same key returns the unit held and writes nothing |
A caller needs the strategy rung and a token with the act grant. The platform or the desktop app serves this route.
## Example
The example sends the smallest body that KeepProxyInput allows. The build validates it against the schema of KeepProxyInput.
