Endpoint
POSThttps://api.relaystation.ai/v1/pdf/metadataWhen to prefer
Choose this endpoint when you need to programmatically read or write standard PDF metadata fields (title, author, keywords, dates) without full document parsing or OCR. It is purpose-built for metadata operations only and is more cost-efficient than full document ingest pipelines for this narrow task.
Side effects
- Invalid or corrupted PDF file returns an error
- PDF is password-protected and metadata cannot be accessed
- Missing required file input returns validation error
- Unsupported metadata field name returns error
- Network timeout for large PDF uploads
