Chainpoint

API

Global network for anchoring data to the Bitcoin blockchain

Overview

Chainpoint provides RESTful APIs for anchoring data hashes to the Bitcoin blockchain via a global distributed network. Core endpoints include creating cryptographic proofs (POST /proofs), retrieving proofs by ID (GET /proofs/{id}), and verifying proof validity (POST /verify). Responses are JSON-formatted, containing proof details and blockchain anchor metadata. Use cases include immutable timestamping of documents, ensuring regulatory compliance with tamper-proof audit trails, verifying supply chain data authenticity, and securing digital asset ownership records.

Example Integration (JavaScript)

script.js JS


fetch('https://tierion.com/chainpoint/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
