Reference direction for model-routing APIs.
Understand the API concepts behind Ethen model routing: request shape, lane selection, response visibility, error handling, and fallback behavior where configured. The page is careful to teach the request model without pretending to be a finished endpoint catalog. Builders get the concepts they need to design responsibly before they rely on exact implementation details.
API documentation for the routing surface.
The API docs explain the reference direction for sending model work through Ethen at the concept level rather than as a substitute for verified endpoints, SDKs, credentials, or install commands. The focus is how a request maps to a model lane, what response visibility can include, how errors and fallback behavior can be represented, and how API events connect back to evidence and workspace history. That means focusing on request shape, model-lane selection, response visibility, error expectations, and evidence rather than inventing commands, SDK behavior, or schemas the repo does not verify.
- Explain request shape concepts before exact endpoints are documented. A clear mental model reduces later integration mistakes.
- Map API requests to flagship, open, and local model lanes where supported. Lane selection should be explained by task and policy, not only by names.
- Describe response visibility, request history, and evidence records. Response visibility matters because operational review often begins after the call completes.
- Explain errors and fallback behavior where configured. Error handling is part of integration design and deserves conceptual clarity.
- Connect API documentation to Gateway and Platform API pages. Evidence matters because the request path should be inspectable later.
API documentation capabilities
The page gives builders a clear model for how an Ethen API reference should work once implementation details are finalized. The page should help builders reason about how an Ethen API surface ought to behave once the implementation details are verified elsewhere.
Request shape direction
Explain the conceptual fields a model-routing request may need, such as task, context, lane preference, and workflow metadata. Request concepts help teams structure integrations before code is committed.
Routing concepts
Show how requests can move through flagship, open, or local lanes depending on configuration and use case. Lane concepts matter because model choice is part of the product philosophy.
Response visibility
Describe how responses can include output, status, route information, and evidence links where available. Response and output concepts matter because the result should be reviewable.
Error behavior
Frame errors as visible states that help users inspect what happened and decide whether to retry, review, or change a route. Error concepts matter because resilient integrations need a visible failure story.
Fallback behavior where configured
Explain how configured fallback paths can change a request route while keeping the decision visible. Evidence concepts matter because the path behind a request can affect product decisions later.
Evidence connection
Connect API requests and responses to workspace receipts, logs, and review records. Policy concepts matter because not every task should follow the same route.
How to read the API docs
The API docs should help builders understand the request lifecycle before they rely on exact implementation details. Conceptual API docs should reduce ambiguity before a builder reaches for exact reference details.
Start with the request goal
Identify the model work being requested: chat, summarization, coding, review, extraction, workflow step, or local-lane task. Begin with the job the request is supposed to do.
Map the lane
Understand how the request may use flagship, open, or local lanes based on configuration. Map that job to lane and policy concepts.
Review the response model
Look for output, status, route information, evidence links, and error details where available. Understand what the response should make visible.
Plan fallback behavior
Use Gateway docs to understand fallback behavior where configured and how route changes remain visible. Plan for errors, review, and evidence before writing integration code.
Connect to evidence
Treat API calls as part of workspace history so important outputs can be reviewed later. Move to verified implementation detail only where the docs can prove it.
Visibility and control
API behavior should be observable enough for builders to debug and review. Good API docs teach not only how to send a request, but how to reason about what comes back and what should be recorded.
Request visibility
Understand how a request is represented in the workspace record. Visible request concepts help builders debug later.
Route visibility
See which model lane handled the request where supported. Lane visibility matters because route policy can affect behavior.
Error visibility
Use error states to decide whether to retry, change context, or inspect fallback behavior. Response visibility matters because teams often need more than the final text.
Evidence visibility
Connect API output to receipts and review records. Evidence visibility keeps the operational record aligned with the integration design.
What this page represents
This page explains the reference direction for model-routing APIs. It is a conceptual guide to request flow, response visibility, errors, and fallback behavior while exact implementation details belong in verified API docs. The page intentionally stops short of inventing exact endpoints, SDK signatures, or command examples beyond what the repo can verify elsewhere.
