Use it to generate one page per device model. Device models hidden from third parties are excluded; with a manufacturer secret key, `include_forbidden` adds that manufacturer's own hidden models. ## OpenAPI ````yaml device-manufacturer-guidance/manufacturer-api/openapi.json GET /device_models/route_params openapi: 3.1.0 info: title: Seam Ecosystem API version: 1.0.0 description: >- Read what Seam publishes about the devices it supports: manufacturers, device models with their images, variants and capabilities, the providers that integrate them, and the partner apps that support them through Seam. Every endpoint accepts `GET` with query parameters, or `POST` with the same parameters as a JSON body. Successful responses include `"ok": true`. Published content is public, so you can call most endpoints without a key. Send an embed key from a browser, or a secret key from your servers, to identify yourself. servers: - url: https://ecosystem.seam.co/v1 security: [] externalDocs: description: Manufacturer API guide url: https://www.seam.co/docs/device-manufacturer-guidance/manufacturer-api paths: /device_models/route_params: get: tags: - device_models summary: List device model route params description: >- Lists published device model slugs with their manufacturer and device type slugs and `updated_at`, ordered by slug, without variants, images or capabilities.
