Every extraction endpoint you already use works unchanged with a business API key. Only two things differ from a personal integration: you authenticate with an APIB-… key, and you can add one optional header to attribute each request to a client. The request and response bodies are identical to the personal API.
All calls go to the same base URL https://de.eagle-doc.com. Documents are uploaded as multipart/form-data with a single file field (PNG, JPEG or PDF) — exactly as today.
🔁
Same bodies, same responses
Because the payloads are identical to the personal API, this page does not repeat the field-by-field tables. For every endpoint below, follow the “Full field reference” link to its complete request and response documentation.
Request headers
Only the headers below change how a request is authenticated and attributed. Everything else about the request is the same as a personal-key call.
Header
Description
api-keyRequired
Your business API key, e.g. APIB-your-business-key. The APIB- prefix is what makes the call business-scoped.
x-sub-business-ref x-sub-business-idOptional
Attributes the request to one of your clients. Send x-sub-business-ref with your own client number, or x-sub-business-id with the Eagle Doc client id. See the Clients & attribution guide.
Content-Type
Set to multipart/form-data for the file upload. Most HTTP clients add this automatically when you attach the file field.
🏢
Attributing to the business itself
Omit the client header entirely to attribute the request to the main business rather than to a specific client.
Any-Document OCR
Extract structured data from an arbitrary document. With a business key, add the optional client header to attribute the extraction.
Parameters
Name
Description
api-key (header)
Your business API key (APIB-…). Required.
x-sub-business-ref (header)
Optional. Your client number, to attribute the request to a client. Alternatively send x-sub-business-id with the Eagle Doc client id. Omit both to attribute to the business itself.
file (form-data)
The document to process (PNG, JPEG or PDF), sent as multipart/form-data.
Extract structured invoice data. Authentication and client attribution work exactly as for the other endpoints.
Parameters
Name
Description
api-key (header)
Your business API key (APIB-…). Required.
x-sub-business-ref (header)
Optional. Your client number, to attribute the request to a client. Alternatively send x-sub-business-id with the Eagle Doc client id. Omit both to attribute to the business itself.
file (form-data)
The document to process (PNG, JPEG or PDF), sent as multipart/form-data.
import requests
resp = requests.post(
"https://de.eagle-doc.com/api/invoice/v1/processing",
headers={
"api-key": "APIB-your-business-key",
"x-sub-business-ref": "A-1023", # your own client number
},
files={"file": open("invoice.pdf", "rb")},
)
print(resp.json())
import fs from "node:fs";
const form = new FormData();
form.append("file", new Blob([fs.readFileSync("invoice.pdf")]), "invoice.pdf");
const resp = await fetch("https://de.eagle-doc.com/api/invoice/v1/processing", {
method: "POST",
headers: {
"api-key": "APIB-your-business-key",
"x-sub-business-ref": "A-1023", // your own client number
},
body: form,
});
console.log(await resp.json());
🧾
Base64 variant
A base64 variant is available at /api/invoice/v1/base64/processing for integrations that prefer to send the file as an encoded string instead of multipart. It accepts the same business key and client header.

Request and response bodies are identical to the personal API. See the complete field reference: Invoice OCR full reference →
Receipt OCR
Extract structured receipt data. The business key and optional client header behave the same as everywhere else.
