HashProof

什麼是 HashProof？

HashProof is an API that lets developers and AI agents issue verifiable credentials instead of PDFs. Most certificate tools are SaaS platforms. HashProof takes a different approach: a simple API with pay-per-use pricing. Each credential costs 0.10 USDC using x402, with metadata stored on IPFS and a hash registered on the blockchain for public verification. Developers can create templates, place dynamic values on designs, and define expiration dates for memberships or permanent credentials.
