Needs `analytics.read`, `product.read` and `evaluation.readInference` on the product, else 403. A product that does not exist answers 404. ## OpenAPI ````yaml /openapi.json get /analytics/inference openapi: 3.0.0 info: version: 1.0.0 title: Product Management Service API description: API documentation for Product Management Service contact: name: Galtea AI servers: - url: https://api.galtea.ai security: - bearerAuth: [] tags: [] externalDocs: description: Galtea Platform Documentation url: https://docs.galtea.ai paths: /analytics/inference: get: tags: - analytics summary: Get latency, cost and tokens per version for a product description: >- The average latency (ms), cost (USD), input tokens and output tokens per version, per test type and pooled over the test types, with the filters of `GET /analytics`, except that `metricIds` and `specificationIds` do not narrow this response.
