Strale PDF Extract

Choose this endpoint when you need to extract specific, named data fields from a PDF using plain English instructions rather than fixed templates or hard-coded parsers. It is especially useful for heterogeneous PDF formats (invoices, contracts, reports) where structure varies across documents. The natural language extraction parameter makes it flexible enough to handle novel document types without custom code. The cryptographic audit record is valuable when provenance and tamper-evidence of the extracted data matter.

• PDF URL is inaccessible or requires authentication — returns error indicating fetch failure
• PDF is password-protected or encrypted — extraction fails with unsupported format error
• Ambiguous extraction instruction yields incomplete or mismatched fields
• Very large or complex PDFs may time out or return partial results
• Neither url nor base64 provided — returns validation error for missing input
• Malformed base64 string causes decoding failure
