# Reference (/api) Endpoints The API reference is generated from the Vizit Public API OpenAPI specification. Every operation has a page with its request and response schemas, parameters, and code samples. For behaviors that apply across the API — authentication, error shapes, pagination — see the [standards](/standards/authentication) pages. ## Authentication [#authentication] Exchange client credentials for short-lived Bearer tokens used on protected endpoints. * [Obtain an access token](/api/authentication/createToken) ## Product Details [#product-details] Create, update, and retrieve Product Detail Page (PDP) content for ingestion into Vizit. * [List product categories](/api/product-details/listProductCategories) * [Submit a PDP by GTIN](/api/product-details/upsertPdpByGtin) * [Retrieve PDP scores by GTIN](/api/product-details/getPdpByGtin) * [Submit a PDP by Amazon ASIN](/api/product-details/upsertPdpByAsin) * [Retrieve PDP scores by ASIN](/api/product-details/getPdpByAsin) ## Exports [#exports] Create and poll asynchronous bulk export jobs for PDP and image scores, then download their CSV artifacts. * [Create a bulk export job](/api/exports/createExport) * [Retrieve an export](/api/exports/getExport) * [Download an export artifact](/api/exports/downloadExport) ## Images [#images] Submit standalone images for asynchronous scoring and poll for their results. * [Submit an image for scoring](/api/images/scoreImage) * [Retrieve an image score](/api/images/getImageScore) ## Spark Ideas [#spark-ideas] Request Spark Ideas (written suggestions for a root image) and poll for their results. * [Request a Spark Idea](/api/spark-ideas/createSparkIdea) * [Retrieve a Spark Idea](/api/spark-ideas/getSparkIdea) ## Spark Images [#spark-images] Request Spark Images (generated image variations for a root image) and poll for their results. * [Request a Spark Images batch](/api/spark-images/createSparkImagesBatch) * [Retrieve a Spark Images batch](/api/spark-images/getSparkImagesBatch)
