Quote Parsing API

Extract JSON data from quote PDFs and images using your schema.

Try It Live

Extract structured JSON from the preloaded sample, then switch to your own document when you are ready.

Document

sample-quote.pdf

Add fields, nested object fields, and lists of objects to build your schema.

Ready to try it on your own document?

We will save your file and schema so you can pick up where you left off after sign-in.

Use via API

Drop the same schema into your stack. Pick a language tab to copy a request that uses the sample document and starter schema.

Quote Parsing API in TypeScript

Type-safe TypeScript example using fetch and a JSON schema. Drop into Next.js, Express, or any Node runtime.

typescript
import { readFileSync } from 'node:fs';

const schema = {
  "type": "object",
  "properties": {
    "seller": {
      "type": "string",
      "description": "Seller or issuing company name"
    },
    "buyer": {
      "type": "string",
      "description": "Buyer or prospect name"
    },
    "quote_number": {
      "type": "string",
      "description": "Quote number or reference"
    },
    "quote_date": {
      "type": "string",
      "description": "Quote issue date"
    },
    "expiration_date": {
      "type": "string",
      "description": "Quote expiration date"
    },
    "subtotal": {
      "type": "number",
      "description": "Subtotal before tax and fees"
    },
    "tax": {
      "type": "number",
      "description": "Tax amount"
    },
    "total": {
      "type": "number",
      "description": "Quoted total amount"

    "quote_number",
    "quote_date",
    "expiration_date",
    "subtotal",
    "tax",
    "total"
  ]
};

const file = new File([readFileSync('sample-quote.pdf')], 'sample-quote.pdf', {
  type: 'application/pdf',
});

const formData = new FormData();
formData.set('file', file);
formData.set('schema', JSON.stringify(schema));

const response = await fetch('https://api.structpdf.com/v1/extract', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.STRUCTPDF_API_KEY}`,
  },
  body: formData,
});

const data = await response.json();
console.log(data);

Quote Parsing API in Python

Python example using requests. Works on Python 3.8+ and integrates cleanly with Django, FastAPI, and ETL pipelines.

python
import json
import os
import requests

schema = {
  "type": "object",
  "properties": {
    "seller": {
      "type": "string",
      "description": "Seller or issuing company name"

with open("sample-quote.pdf", "rb") as fh:
    response = requests.post(
        "https://api.structpdf.com/v1/extract",
        headers={"Authorization": f"Bearer {os.environ['STRUCTPDF_API_KEY']}"},
        files={"file": ("sample-quote.pdf", fh, "application/pdf")},
        data={"schema": json.dumps(schema)},
    )

response.raise_for_status()
print(response.json())

Quote Parsing API in Java

Java example using HttpClient. Works on Java 11+ and integrates with Spring Boot or any JVM service.

java
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.nio.file.Files;
import java.nio.file.Path;
import java.util.UUID;

public class ExtractExample {
  public static void main(String[] args) throws Exception {
    String schema = "{\"type\":\"object\",\"properties\":{\"seller\":{\"type\":\"string\",\"description\":\"Seller or issuing company name\"},\"buyer\":{\"type\":\"string\",\"description\":\"Buyer or prospect name\"},\"quote_number\":{\"type\":\"string\",\"description\":\"Quote number or reference\"},\"quote_date\":{\"type\":\"string\",\"description\":\"Quote issue date\"},\"expiration_date\":{\"type\":\"string\",\"description\":\"Quote expiration date\"},\"subtotal\":{\"type\":\"number\",\"description\":\"Subtotal before tax and fees\"},\"tax\":{\"type\":\"number\",\"description\":\"Tax amount\"},\"total\":{\"type\":\"number\",\"description\":\"Quoted total amount\"}},\"required\":[\"seller\",\"buyer\",\"quote_number\",\"quote_date\",\"expiration_date\",\"subtotal\",\"tax\",\"total\"]}";
    Path file = Path.of("sample-quote.pdf");
    String boundary = UUID.randomUUID().toString();
    String CRLF = "\r\n";

    var body = new java.io.ByteArrayOutputStream();
    body.writeBytes(("--" + boundary + CRLF
        + "Content-Disposition: form-data; name=\"schema\"" + CRLF + CRLF
        + schema + CRLF).getBytes());
    body.writeBytes(("--" + boundary + CRLF
        + "Content-Disposition: form-data; name=\"file\"; filename=\"sample-quote.pdf\"" + CRLF
        + "Content-Type: application/pdf" + CRLF + CRLF).getBytes());
    body.writeBytes(Files.readAllBytes(file));
    body.writeBytes((CRLF + "--" + boundary + "--" + CRLF).getBytes());

    HttpRequest request = HttpRequest.newBuilder()
        .uri(URI.create("https://api.structpdf.com/v1/extract"))
        .header("Authorization", "Bearer " + System.getenv("STRUCTPDF_API_KEY"))
        .header("Content-Type", "multipart/form-data; boundary=" + boundary)
        .POST(HttpRequest.BodyPublishers.ofByteArray(body.toByteArray()))
        .build();

    HttpResponse<String> response = HttpClient.newHttpClient()
        .send(request, HttpResponse.BodyHandlers.ofString());
    System.out.println(response.body());
  }
}

Quote Parsing API in Go

Go example using net/http. Idiomatic Go HTTP client suitable for microservices and serverless functions.

go
package main

import (
	"bytes"
	"fmt"
	"io"
	"mime/multipart"
	"net/http"
	"net/textproto"
	"os"
)

func main() {
	schema := `{"type":"object","properties":{"seller":{"type":"string","description":"Seller or issuing company name"},"buyer":{"type":"string","description":"Buyer or prospect name"},"quote_number":{"type":"string","description":"Quote number or reference"},"quote_date":{"type":"string","description":"Quote issue date"},"expiration_date":{"type":"string","description":"Quote expiration date"},"subtotal":{"type":"number","description":"Subtotal before tax and fees"},"tax":{"type":"number","description":"Tax amount"},"total":{"type":"number","description":"Quoted total amount"}},"required":["seller","buyer","quote_number","quote_date","expiration_date","subtotal","tax","total"]}`

	file, err := os.Open("sample-quote.pdf")
	if err != nil {
		panic(err)
	}
	defer file.Close()

	var body bytes.Buffer
	writer := multipart.NewWriter(&body)
	_ = writer.WriteField("schema", schema)

	header := make(textproto.MIMEHeader)
	header.Set("Content-Disposition", "form-data; name=\"file\"; filename=\"sample-quote.pdf\"")
	header.Set("Content-Type", "application/pdf")
	part, err := writer.CreatePart(header)
	if err != nil {
		panic(err)
	}
	if _, err := io.Copy(part, file); err != nil {
		panic(err)
	}
	writer.Close()

	req, err := http.NewRequest("POST", "https://api.structpdf.com/v1/extract", &body)
	if err != nil {
		panic(err)
	}
	req.Header.Set("Authorization", "Bearer "+os.Getenv("STRUCTPDF_API_KEY"))
	req.Header.Set("Content-Type", writer.FormDataContentType())

	resp, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()

	out, _ := io.ReadAll(resp.Body)
	fmt.Println(string(out))
}

Frequently Asked Questions

What does the Quote Parsing API return?

Send a quote PDF or image plus a JSON schema and get back structured JSON shaped exactly like your schema, alongside per-field findings, snippets, and page references that explain where each value came from.

Which file formats are supported?

PDFs and common image formats all flow through the same extraction endpoint, so exported quotes, scans, and screenshots can be ingested in one call.

How is usage priced?

Extractions are billed per page in credits. There is no separate parse charge before extraction — the credit you see is the credit you pay.

Can I customize the fields I extract?

Yes. Edit the schema in the playground or build it visually in the Schema Builder. Save it once and reuse it in production via schema_id, including nested objects and line-item arrays.

Do I have to sign up to try it?

No. Run the demo on a sample quote without an account. When you upload your own quote, we ask you to sign in with Google or a magic link to run your first extraction. Your file and schema are saved automatically so you pick up where you left off.
