Immutable trade confirmations for compliance‑first Fin‑tech apps
Regulators, auditors, and SOC 2 reviewers all ask for the same thing: unchangeable evidence of what really happened on your trading platform. Every filled order, K‑line candle, swap quote, or depth‑of‑book snapshot needs to live forever in a format nobody can edit later. Screenshots are nice for a quick look, but PDFs are safer—self‑contained, hard to tamper with, and easy to sign or hash.
How ScreenshotOne can help?
ScreenshotOne’s PDF API fits the job perfectly:
- Any source, one call. Pass a live URL or raw HTML and get back a pixel‑perfect PDF of the chart, order book, or confirmation screen—no headless browser to maintain.
- Immutable by design. Store the PDF as‑is, add a SHA‑256 hash to your ledger, and you’ve got write‑once proof that satisfies SOC 2 control CC7 and most securities‑law retention rules.
- Scales with the market. Whether you’re capturing one trade per minute or thousands per second during a crypto surge, the API queues and streams PDFs without throttling your app.
Quick start
curl https://api.screenshotone.com/take \ -d access_key=<your access key> \ -d url=https://example.com/receipt \ -d format=pdf \The call above grabs the trade‑receipt page, bakes it into an PDF with all CSS intact, and returns it.
Next step: Plug the PDF URL or hash into your audit log table, and you’re done—immutable evidence on tap for every trade your platform ever executes.
ScreenshotOne is one of those rare tools that just does its job perfectly. It's simple to integrate, consistently delivers great results, and the support is excellent.
We tested a few alternatives and ScreenshotOne was the clear winner for both quality and ease of use. We'd love to see the option to capture different screen formats too, like tablet and mobile, to support a more complete analysis.
