A technical surface for routing model work.
Use the platform API direction to connect product and workflow requests to Ethen's model routing layer, with request history, usage visibility, and fallback behavior where configured. The page explains how builders can think about a shared request path before they commit to exact implementation details. It keeps the focus on route intent, request visibility, usage awareness, and provider boundaries instead of inventing a finished catalog.
A model API that belongs to the workspace.
The Platform API is the technical surface for sending model work into Ethen. It makes model-lane selection, request history, usage signals, fallback behavior, and evidence easier to review without hardcoding every product feature to one provider path. That makes the API direction useful even before every endpoint detail is finalized. The builder gets the mental model for how a request should move and how the surrounding evidence should stay visible.
- Route model requests through a shared platform surface. A clean request path helps products evolve without provider-specific sprawl.
- Keep request history and route decisions connected to the workspace. Lane selection should be understandable by task, not treated as invisible infrastructure.
- Support fallback behavior where configured with route decisions kept visible. Evidence and logs matter because API behavior often becomes operational behavior.
- Expose usage signals by route, workflow, or model lane where data is available. Provider responsibility should remain clear where customer-managed settings or upstream policies apply.
- Connect application and workflow surfaces to flagship, open, and local model lanes. Fallback should be described as configured behavior, not as a universal guarantee.
API capabilities
The Platform API gives builders a predictable way to move model work through Ethen while keeping operational details visible enough to reason about. It gives builders a conceptual foundation for integrating model work while staying honest about the line between platform direction and verified implementation.
Model routing surface
Send requests toward flagship, open, or local lanes based on task, configuration, and workflow needs. The goal is one understandable request surface instead of many direct integrations.
Request visibility
Organize request history, route decisions, status, and evidence so teams can inspect model behavior later. Visibility matters because routing choices often affect quality, cost, and privacy posture.
Usage visibility
Surface usage signals by route, workflow, or lane where data is available, giving teams a clearer view of model work patterns. Usage context helps teams reason about demand and policy without promising billing outcomes.
Fallback behavior where configured
Define fallback paths for unavailable or unsuitable lanes and make the routing change visible to developers. Error handling is part of the user experience and should be reviewable.
Workflow integration
Let repeatable workflows call a shared API surface instead of embedding model selection across every step. Provider boundaries matter because an integration should not hide who owns what.
Local lane support where configured
Bring local model routes into the same API design direction as hosted lanes when the environment supports it. Evidence keeps the request path inspectable after the response has returned.
How API routing works
The API direction is built around a reviewable request path. A conceptual API page should help a builder think clearly before writing production code.
The product sends a request
An application, workflow, or workspace surface sends model work through a platform API path. Start with the product job the request is meant to do.
The route is resolved
The request is matched to a model lane based on task type, configuration, and available context. Choose a lane or policy that fits the task and the available configuration.
The model lane handles the work
A flagship, open, or local lane handles the request where supported by the platform configuration. Keep request and response details visible enough to review later.
The request history is recorded
Route choice, status, usage signals, and evidence can be attached to the workspace history. Attach logs, evidence, and notes where the route matters operationally.
Fallback planning stays visible
When configured fallback behavior changes the route, the decision remains inspectable in the workspace record. Treat fallback and retries as configured policy decisions rather than blanket promises.
Visibility and control
A routing API is most useful when builders can understand request decisions after the fact. Builders need to know what happened after a call, not only that a call returned.
Request history
See the path a request took and the model lane that handled it. Request history should help teams debug product behavior with less guesswork.
Usage signals
Review usage patterns by route, workflow, or lane where data is available. Route visibility makes policy changes easier to reason about.
Fallback notes
Understand when configured fallback behavior changed a request path. Provider boundaries keep responsibility clear when outside services are involved.
Evidence links
Connect API events to workspace outputs, logs, and receipts. Evidence creates a better record for review, operations, and later design work.
What this page represents
This page explains the technical API direction for routing model work through Ethen. It describes request visibility and control surfaces, not a fixed provider catalog or service guarantee. It stays at the level of verified direction so the docs do not overstate providers, endpoints, or behavior the repo has not locked down.
