      "description": "Submit one locally calculated Verifyum version 2 commitment. Accepts only the commitment and an idempotency key. Never send a file, filename, raw file hash, nonce or private manifest. The caller must hash the file and build the private manifest on its own machine first, as documented at https://verifyum.com/agents. This creates a real public transaction on Solana Mainnet. Public use is currently free and the network fee is currently paid by AI SENSE AS. That is a current service policy, not a permanent pricing guarantee. Create proofs only on clear user intent, never speculatively, in bulk, or as a hidden side effect. When retrying, reuse the exact same commitment and idempotency key.",

The response also contains the exact Solana RPC call and expectations so the caller can independently confirm the transaction on chain, because this hosted check is performed by the Verifyum service itself. A finalized Verifyum anchor demonstrates that a commitment to exact file bytes existed no later than the estimated Solana block time. It does not prove authorship, ownership, legal signature validity, when the file was first created, or whether statements inside the file are true.",
