Use the Forms API to parse PDFs, fill forms from natural-language instructions, and download completed documents.

​
Core workflow

  1. Call POST /parse with a PDF file.
  2. Poll GET /parse/{job_id} until status = succeeded.
  3. Call POST /fill with the parsed file_id and your prompt.
  4. Poll GET /fill/{job_id} until status = succeeded.
  5. Download from the returned download_url.
This API is asynchronous by design. Write clients to submit work, poll status, then continue once a job succeeds.

​
Parse example

curl -X POST "https://api.sylvian.ai/parse" \
  -H "X-API-Key: forms_sk_your_key" \
  -F "[email protected]"

​
Fill example

curl -X POST "https://api.sylvian.ai/fill" \
  -H "X-API-Key: forms_sk_your_key" \
  -F "file_id=<parsed-file-id>" \
  -F "prompt=Fill in the customer name, date, and signature fields."
