Request attachment text
Extract readable text from an attachment up to 7500000 bytes, at no extra charge. Repeating this request reuses the same current source extraction for 24 hours; no request body or Idempotency-Key is needed. Conversion runs for at most 30 seconds. OCR is unavailable. Current mailbox access and the source attachment are checked before serving cached text. If extraction cannot complete, use the original attachment download.
