What it does
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.
HashProof lets developers and platforms create certificates anyone can verify.
