Parse & classify

Build a parser for any document.

Define your own field schema and extract exactly what you need, or let PDF4me classify mixed batches and route each file by type. This is the custom engine. Ready-made invoice and receipt parsers live on AI data extraction.

Open the analyzer dashboard See Parse and Classify
Two endpoints

Parse extracts. Classify routes.

Use them together on a mixed inbox, or call Parse alone when you already know the document type. Ready-made parsers for invoices and receipts are a different product.

Parse Document

Send a document and a parse definition. Get JSON keyed to the fields you named. The most flexible AI endpoint for any layout, including forms you have never seen before.

Set up Parse

Classify Document

Send a document and get the predicted type (invoice, contract, receipt) plus a confidence score. Use it as the routing step before you parse.

Parse Document

Extract exactly the fields you name.

Parse Document is the universal AI endpoint. Provide a document and a parse definition; receive JSON keyed by your field schema. Native actions in Power Automate, Make and n8n.

The schema

Four keys describe any field.

  • Describe the fields. Write a parse definition: each field has a fieldName, a fieldType and a plain-language fieldDescription. Or build the same schema as a Parse Analyzer in the dashboard.
  • POST the document. Send Base64 docContent with docName to /api/v2/ParseDocument, plus your Analyzer Id or parse definition.
  • Read the JSON. The response carries parsedData keyed to your schema, plus documentType and pageCount.
  • fieldName is the JSON key you get back.
  • fieldType is string, number, date, or table for repeating rows.
  • fieldDescription is the plain-language hint. List alternate labels for accuracy.
  • fieldMethod is optional: extract takes the value as printed, generate derives or normalises it.

Classify Document

Know the type before you parse it.

Classify Document predicts whether a file is an invoice, contract, receipt or another type, with a confidence score. Use it to sort a mixed batch, then parse each file by type.

The verdict

One POST, type plus confidence.

  • POST the document. Base64-encode the PDF and send it as docContent with a docName to /api/v2/ClassifyDocument.
  • Read the verdict. The response returns documentType, category and a confidence score between 0.0 and 1.0.
  • Branch, then parse. Route high-confidence files to the matching parser. Queue low-confidence ones for review. For mixed inboxes, a Classify Analyzer can route and extract in one call.

Dashboard analyzers

Build the schema once, call it everywhere.

A Parse Analyzer or Classify Analyzer in the dashboard gives you a stable Analyzer Id for the REST API, Power Automate, Make, n8n and Zapier. Custom forms that are not in the ready-made set live here.
