iota_notarize
shallowio.agentsvc/services · Verify this server
Proof of existence on the IOTA mainnet: send text, a SHA-256 hash or a URL and get a tamper-proof timestamp. We store only the SHA-256 (never your content) in a locked notarization of the official IOTA Notarization package: it cannot be changed or transferred and its deletion is locked until 2106. Returns object id, transaction digest, ledger time and explorer links. Use for contracts, invoices, AI outputs, datasets, web page evidence or audit logs. Check later with iota-verify. Network fee included. Price: $0.01 USDC per call, paid inside this MCP call via x402 (USDC on Base, Solana, Polygon or Arbitrum). x402 MCP clients such as @x402/mcp pay automatically. Free sample: call with the example input {"text":"Invoice 2026-1042, total 1,250.00 EUR, issued 2026-10-11"}.
