```
require 'uri'
require 'net/http'

url = URI("https://app.barndoor.ai/api/llm-gateway/admin/governance-config")

http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true

request = Net::HTTP::Put.new(url)
request["Authorization"] = 'Bearer <token>'
request["Content-Type"] = 'application/json'
request.body = "{\n  \"require_pricing_for_mappings\": true\n}"

response = http.request(request)
puts response.read_body
```

### Response

```json
{
  "require_pricing_for_mappings": true
}
```

### Authorizations

- **Authorization**: JWT obtained through Barndoor's authentication flow. Pass the token verbatim in `Authorization: Bearer <token>`.

### Body
- **require_pricing_for_mappings**: When `true`, the gateway refuses to enable a model route whose `upstream_model` has no pricing configured. Use this to guarantee every billable request has a known unit cost.

### Response
- **200**: The updated configuration.
