HashProof issues verifiable credentials (diplomas, course completions, attendance, memberships) with one API call — no account, no API key, no human onboarding. $0.10 USDC per credential, paid via x402 on Base (eip155:8453) or Celo (eip155:42220). Every credential is registered on-chain in the CredentialRegistry contract on Celo (0x7a1B759A602Aba72a70f99Dffd0a386d7504ce9B), pinned to IPFS, and delivered as a PDF with a QR code anyone can scan to verify for free against three independent sources: database, IPFS and blockchain. Agent flow: GET /templates/:ref/requirements (free) to discover required fields, POST /templates/:ref/preview (free) to check the layout, POST /issueCredential ($0.10 via x402) to issue, then share https://hashproof.dev/verify/:id. Verification is always free and public. Also available as an MCP server (npx hashproof-mcp, in the official MCP registry) and as an agent skill. Full guide: https://hashproof.dev/skill.md
