# List Schema
Models written to Permify using the [write schema API](./write-schema) can be listed using this API with the timestamps at which the models were created.
Request needs to be made to the API endpoint **/v1/tenants/{tenant_id}/schemas/list** to list all the models.
### Example Request on Postman
**POST** `/v1/tenants/{tenant_id}/schemas/list`

Any:

properties:
'@type':
type: string
description: >-
A URL/resource name that uniquely identifies the type of the
serialized
protocol buffer message. This string must contain at least
one "/" character. The last segment of the URL's path must represent
the fully qualified name of the type (as in
`path/google.protobuf.Duration`). The name should be in a canonical
form
(e.g., leading "." is not accepted).
In practice, teams usually precompile into the binary all types that
they
expect it to use in the context of Any. However, for URLs which use
the
scheme `http`, `https`, or no scheme, one can optionally set up a
type
server that maps type URLs to message definitions as follows:
* If no scheme is provided, `https` is assumed.
* An HTTP GET on the URL must yield a [google.protobuf.Type][]
value in binary format, or produce an error.
* Applications are allowed to cache lookup results based on the
URL, or have them precompiled into a binary to avoid any
lookup. Therefore, binary compatibility needs to be preserved
on changes to types. (Use versioned type names to manage
breaking changes.)
Note: this functionality is not currently available in the official
protobuf release, and it is not used for type URLs beginning with
type.googleapis.com. As of May 2023, there are no widely used type
server
implementations and no plans to implement one.
Schemes other than `http`, `https` (or the empty scheme) might be
used with implementation specific semantics.

description: >-
`Any` contains an arbitrary serialized protocol buffer message along
with a
URL that describes the type of the serialized message.
Protobuf library provides support to pack/unpack Any values in the form
of utility functions or additional generated methods of the Any type.
Example 1: Pack and unpack a message in C++.
Foo foo = ...;
Any any;
any.PackFrom(foo);
...
if (any.UnpackTo(&foo)) {
...
}
Example 2: Pack and unpack a message in Java.
Foo foo = ...;
Any any = Any.pack(foo);
...
if (any.is(Foo.class)) {
foo = any.unpack(Foo.class);
}
// or ...
if (any.isSameTypeAs(Foo.getDefaultInstance())) {
foo = any.unpack(Foo.getDefaultInstance());
}
Example 3: Pack and unpack a message in Python.
foo = Foo(...)
any = Any()
any.Pack(foo)
...
if any.Is(Foo.DESCRIPTOR):
any.Unpack(foo)
...
Example 4: Pack and unpack a message in Go
foo := &pb.Foo{...}
any, err := anypb.New(foo)
if err != nil {
...
}
...
foo := &pb.Foo{}
if err := any.UnmarshalTo(foo); err != nil {
...
}
The pack methods provided by protobuf library will by default use
'type.googleapis.com/full.type.name' as the type URL and the unpack
methods only use the fully qualified type name after the last '/'
in the type URL, for example "foo.bar.com/x/y.z" will yield type
name "y.z".
JSON
====
The JSON representation of an `Any` value uses the regular
representation of the deserialized, embedded message, with an
additional field `@type` which contains the type URL. Example:
package google.profile;
message Person {
string first_name = 1;
string last_name = 2;
}
{
"@type": "type.googleapis.com/google.profile.Person",
"firstName": ,
"lastName":
}
If the embedded message type is well-known and has a custom JSON
representation, that representation will be embedded adding a field
`value` which holds the custom JSON in addition to the `@type`
field. Example (for message [google.protobuf.Duration][]):
{
"@type": "type.googleapis.com/google.protobuf.Duration",
"value": "1.212s"
}
