What you need

A file your business system produced: an invoice, a statement run, a report. The original, exactly as it came out. Not a PDF, not something re-saved from a text editor.

If your system prints to a file, or spools to a queue you can copy from, that file is what you want.

No file to hand?

Open the app and press Load demo. It opens a sample statement run with its template already built, so you can press Extract and see the JSON straight away. Nothing to sign up for, and nothing to download.

API reference

Mon, 01 Jan 0001 00:00:00 +0000

Base URL https://reamline.com. Authenticate with an API key in the x-api-key header, or a session token as Authorization: Bearer.

Requests and responses are JSON throughout. Every request sends the document either as text (a plain string) or textB64 (base64 of the original bytes). Prefer textB64, for the reasons in encoding.

POST /v1/extract

Turn a document into JSON.

curl -s -X POST https://reamline.com/v1/extract \
 -H "Content-Type: application/json" -H "x-api-key: $KEY" \
 -d '{"templateId":"tpl_...","textB64":"..."}'

Field
`textB64` or `text`	The document. Required.
`templateId`	Which document type to use. Omit it and the service works it out from your recognition rules.
`revision`	Pin to a specific published version. Defaults to the live one.
`template`	An inline template object, instead of a stored one. Useful for testing without publishing.

The response carries one entry per document found:

The payment that vanished

Sun, 02 Aug 2026 00:00:00 +0000

Here is a customer statement, as the accounts system printed it:

14/04/2026 00153140 I 2071.30
14/04/2026 00153141 I 517.82
15/04/2026 ON A/C P -1294.56
19/05/2026 00153235 I 1176.00
23/06/2026 00153320 I 2589.12
 ────────
 5059.68

Five lines. The script reading it produced four.

The missing one is the payment. The customer had paid £1,294.56 and the statement they received showed four charges adding to £6,354.24 above a total of £5,059.68. A £1,294.56 hole with nothing to explain it, and what was missing was their money.

How it works

Mon, 01 Jan 0001 00:00:00 +0000

You do this once per document type. It takes minutes, and you only ever point at things.

1. Open a real example

Drag in a file your system has produced. It stays in your browser. Nothing is uploaded while you are setting things up.

No file to hand? Press Load demo instead. It opens a sample statement with the finished template already applied, so you can see all five steps at once and press Extract straight away.
