When you make a model request through Waystone, you can optionally provide a unique identifier for the end-user triggering that request to allow Waystone to handle per-user usage tracking. This allows you to:
  • Set quotes on users, groups, or a combination (e.g. no single user in group X can take more than 10% of monthly credits)
  • Monitor model usage to track down service abuse
  • Apply special rules on important users (additional model output checks; model routing etc.)

​
Entities

Waystone allows you to define:
  • user (individuals)
  • group (e.g. orgs or teams)
  • a user and a group
Once a request is sent with both a user and a group, Waystone creates a link between the entities: “user is part of group”; such requests are attached to both the user and the group, and is subject to rules and conditions on both. Once a user is attached to a group, however, any request with just the user provided will only be applied to that user.

​
Metadata

You can attach arbitrary metadata to each user and group, which is then used to apply rulesets. Useful metadata for your application may include:
  • region
  • payment plan / tier of product
  • categories of note, such as “risky” or “vip”

​
Tracking usage

To attach a request to an entity, provide the unique ID for the user or group in your application when making the request. The Waystone API is a superset of the OpenAI API, so the metadata field is used to also provide user identification in user requests: 
  const client = new OpenAI({
    apiKey: process.env["WAYSTONE_API_KEY"],
    baseURL: "https://waystone.run/api/gateway/v1",
  });

  const userMetadata = {
    user: { id: userId, metadata: { tier: "free" }},
  }

  const response = await client.responses.create({
    model: "openai/gpt-4.1-mini",
    input: "Your super special prompt",
    metadata: { waystone: JSON.stringify(userMetadata) }
  });
In this example, the request is attached to a user, which is simulatanously given some additional metadata. Refer to the API for more information.

​
Taking Action on Users

Waystone’s concept of rulesets allows you to automatically take actions on users or groups by their metadata.

Exploring usage

Functionality around exploring entity usage is under development with Waystone beta users. This includes:
  • OTEL on model inputs and outputs
  • Tracking usage (tokens; requests; USD cost)
  • Usage analysis (spikes, abuse detection, etc.)
