You've spent weeks — maybe months — developing your api design. It's original, it's valuable, and it's yours. But how do you prove it? What happens when someone else claims they had the same idea first? Without proof of when your api design was created, you have nothing but your word.
Traditional methods like mailing yourself a sealed envelope (the "poor man's patent") are unreliable and easily challenged. Formal patents cost thousands of dollars and take months to process. But there's a modern solution that's fast, affordable, and mathematically tamper-proof: Bitcoin blockchain timestamping.
Every day you wait is a day someone else could independently develop a similar api design — or worse, steal yours. In the world of intellectual property, the first to prove existence wins. Not the first to create, but the first to have verifiable proof.
A api design is particularly vulnerable because it often exists only as a document, a file, or an idea in your head. Unlike physical inventions, there's no manufacturing date or physical evidence. Digital proof is your strongest defense — and blockchain proof is the strongest form of digital proof available today.
Enter a description of your api design or upload the actual file. Your content is hashed locally — it never leaves your device.
A SHA-256 fingerprint of your api design is permanently recorded on the Bitcoin blockchain with an exact timestamp.
A PDF certificate with blockchain proof, QR code, and verification link is delivered to your email.
Courts worldwide are increasingly recognizing blockchain timestamps as valid evidence. In 2025, a French court accepted Bitcoin blockchain proof as sufficient evidence of IP ownership in a copyright dispute. Chinese, American, Italian, and EU courts have followed similar paths. While this doesn't replace formal patent registration, it provides strong, independently verifiable proof of when your api design was first documented.
Permanent Bitcoin blockchain proof. Certificate in under 2 minutes. $19.
Timestamp for $19 →Yes. You can describe your api design in text, and that description gets timestamped. The more detail you include, the stronger your proof. You can also upload files — documents, designs, code, images — anything that represents your api design.
Each version gets its own timestamp. If your api design evolves, you can create a chain of proof showing how it developed over time. This actually strengthens your claim by showing the progression of your original thinking.
Your files are never stored on our servers — only the SHA-256 hash, which cannot be reverse-engineered into your original content. Your api design stays private. The blockchain records only the proof, not the content.
