+## Service
+
+### `name`
+
+`string`
+
+Name says which service decided, in the verdict's rule.
+
+### `url`
+
+`string`
+
+URL is POSTed the body.
+
+### `header_files`
+
+`map[string]string`
+
+HeaderFiles are headers whose values are read from files each time,
+so a rotated key needs no restart: {Authorization: /etc/…/lakera}.
+
+### `body`
+
+`string`
+
+Body is the request, a template given .Text; {{json .Text}} writes it
+as a JSON string. Empty is {"input": <text>}.
+
+### `blocked`
+
+`string`
+
+Blocked is where in the answer the service says the text is unsafe:
+a dotted path, numbers for list items (results.0.flagged). True, a
+number above zero, a non-empty list or string other than "false" is
+unsafe.
+
+### `reason`
+
+`string`
+
+Reason is where it says why, for the verdict; optional.
+
+### `on`
+
+`string`
+
+On: input, output or both. Empty is input.
+
+### `action`
+
+`string`
+
+Action on unsafe: block or flag. Empty is block.
+
+### `timeout`
+
+`time.Duration`
+
+Timeout bounds one call. Empty is 3s; past it the policy's fail says.
