Introduction

OriginStamp is a web-based, trusted timestamping service that uses the decentralized blockchain to store anonymous, tamper-proof timestamps for any digital content. OriginStamp allows users to hash files, emails, or plain text, and subsequently store the created hashes in the blockchain as well as retrieve and verify timestamps that have been committed to the blockchain. OriginStamp is free of charge and easy to use. It enables anyone, e.g., students, researchers, authors, journalists, or artists, to prove that they were the originator of certain information at a given point in time.

    • and execute them in an automated fashion

Organization

Accordingly, this documentation is divided into three parts:

  1. The Guide that walks you through the setup of your account, how to obtain an API key and how to use both the OriginStamp Dashboard and the OriginStamp API.
  2. The OriginStamp Dashboard part focusing on the use of the OriginStamp Dashboard and how to use it to manage your account, subscription and API key.
  3. The OriginStamp API part emphasizing the embedded use of the OriginStamp API within your own custom pieces of software to automate tamper-proof timestamping for your business cases.

Pricing

You can use both the OriginStamp API and the OriginStamp Dashboard free of charge with a limited amount of monthly credits. For more extensive use cases, our paid plans are well-suited.
