## Core operation

POST /v1/route accepts exactly `request` and `models`. It filters models by health, risk class, data boundary, tool use, structured output, context size, modality, cost, and latency. Eligible models are ranked under `balanced`, `quality`, `cost`, or `latency` objectives. Responses include the selection, ranked candidates, rejected candidates, stable reason codes, score components, and a request ID.

## Important boundaries

- Hosted routing is stateless application logic and does not execute model calls.
- Model metrics and capabilities are supplied by the caller; Nymrel Agent does not certify them.
- The local v0.1 harness executes read-only requests only.
- Provider credentials remain on the customer's machine for local execution.
- Write-capable tools, hosted credential custody, billing, and autonomous side effects are outside v0.1.

## Service

Nymrel offers on-request implementation work for model catalogs, evaluation, routing policy, local adapters, and operational receipts. Scope and pricing are provided after a project brief.
