+## Install Usage License
+
+Install a Harper license for a block of usage. Multiple usage blocks may be installed, and they will be used up sequentially, with the earliest installed blocks used first. A license is installed
+by creating a string that consists of three base64url encoded blocks, separated by dots. The three blocks consist of:
+- `header`: This is a JSON object with two properties:
+  - `typ`: should be "Harper-License"
+  - `alg`: should be "EdDSA"
+
+This JSON object should be converted to base64url (conversion from utf-8 to base64url) and is the first base64url block.
+
+- license payload: This is a JSON object with properties:
+  - `id` _(required)_ - A unique id for the license
+  - `level` _(required)_ - Usage level number
+  - `region` _(required)_ - The region id where this license can be used
+  - `reads` _(required)_ - The number of allowed reads
+  - `readBytes` _(required)_ - The number of allowed read bytes
+  - `writes` _(required)_ - The number of allowed writes
+  - `writeBytes` _(required)_ - The number of allowed write bytes
+  - `realTimeMessages` _(required)_ - The number of allowed real-time messages
+  - `realTimeBytes` _(required)_ - The number of allowed real-time message bytes
+  - `cpuTime` _(optional)_ - The allowed amount of CPU time consumed by application code
+  - `storage` _(optional)_ - Maximum of storage that may be used
+  - `expiration` _(required)_ - The date when this block expires, as an ISO date
+
+This JSON object should be converted to base64url (conversion from utf-8 to base64url) and is the second base64url block.
+
+For example:
+```json
+{
+	"id": "license-717b-4c6c-b69d-b29014054ab7",
+	"level": 2,
+	"region": "us-nw-2",
+	"reads": 2000000000,
+	"readBytes": 8000000000000,
+	"writes": 500000000,
+	"writeBytes": 1000000000000,
+	"realTimeMessages": 10000000000,
+	"realTimeBytes": 40000000000000,
+	"cpuTime": 108000,
+	"storage": 400000000000000,
+	"expiration": "2025-07-25T21:17:21.248Z"
+}
+```
+
+- `signature`: This is the cryptographic signature, signed by Harper, of the first two blocks, separated by a dot, `header.payload`. This is also converted to base64url.
+
+The three base64url blocks are combined to form the `license` property value in the operation.
+
+- `operation` _(required)_ - must always be `install_usage_license`
+- `license` _(required)_ - This is the combination of the three blocks in the form `header.payload.signature`
+
+### Body
+
+```json
+{
+	"operation": "install_usage_license",
+	"license": "abc...0123.abc...0123.abc...0123",
+}
+```
+
+### Response: 200
+
+```json
+{
+	"message": "Successfully installed usage license"
+}
+```
+
+---
+
+## Get Usage Licenses
+
+This will retrieve and return all active usage licenses, with counts of how much of the limits have been consumed.
+
+- `operation` _(required)_ - must always be `get_usage_licenses`
+
+### Body
+
+```json
+{
+	"operation": "get_usage_licenses"
