Public SDK helpers `replace(file)` and `replaceFromFileId(fileId)` upload through the Files API when needed, then send this JSON body. Generated clients send `{ fileId }` JSON only. The HTTP route still accepts a multipart `file` for CLI/internal use; that path is not generated into the public SDKs. ## OpenAPI ````yaml /api-reference/openapi.json put /v1/templates/{id} openapi: 3.1.0 info: title: Eigenpal API version: 1.0.0 description: >- Public REST API for inspecting automations, starting and monitoring runs, managing files, collecting human reviews, and running evaluations. contact: name: Eigenpal url: https://eigenpal.com license: name: Apache-2.0 url: https://www.apache.org/licenses/LICENSE-2.0 servers: - url: https://api.eigenpal.com description: Production (canonical API hostname) security: - bearerAuth: [] tags: - name: Metadata description: Authenticate and inspect the current API context. - name: Models description: >- List text, vision, and OCR models configured for the current tenant environment.
