可搜尋的 PDF 隨附於 2024-07-31-preview prebuilt-read 模型，一般 PDF 耗用量不需要任何使用量成本。
使用可搜尋的 PDF
若要使用可搜尋的 PDF，請使用 作業提出POST要求，並將輸出格式指定為 pdf：Analyze
POST /documentModels/prebuilt-read:analyze?output=pdf
{...}
202
Analyze作業完成後，請提出GET擷取Analyze作業結果的要求。
成功完成時，可以擷取 PDF 並下載為 application/pdf。 此作業允許直接下載 PDF 的內嵌文字格式，而不是Base64編碼的 JSON。
// Monitor the operation until completion.
GET /documentModels/prebuilt-read/analyzeResults/{resultId}

// Upon successful completion, retrieve the PDF as application/pdf.
GET /documentModels/prebuilt-read/analyzeResults/{resultId}/pdf
200 OK
Content-Type: application/pdf
索引鍵/值組
在舊版 API 中，預先建置的檔模型會從窗體和檔中擷取索引鍵/值組。 透過將 keyValuePairs 功能新增至預先建置的版面配置，版面配置模型現在可以產生相同的結果。
索引鍵/值組是文件內的特定範圍，其識別標籤或索引鍵，及其相關的回應或值。 在結構化表單中，這些組別可能是標籤，以及使用者為該欄位輸入的值。 在非結構化文件中，它們可能是根據段落中文字內容而得的合約執行日期。 AI 模型已經過定型，可以根據各種不同的文件類型、格式和結構來擷取可識別的索引鍵和值。
