License Election Certifier

Binds a license election (family, id, optional params) to a named asset and licensor DID, producing a deterministic terms_hash via SHA-256 over the JCS-canonical election core. Emits a portable certificate verifiable by ART-200. Not legal advice.

⚠ This tool produces a deterministic certificate recording a stated license election. It does not constitute a legal agreement, does not guarantee enforceability, and is not legal advice. The licensor remains solely responsible for ensuring the elected license applies to their work. Consult a licensed attorney before relying on any output for commercial or legal decisions.
Presets:
URI, IPFS CID, or identifier for the licensed asset. Examples: ipfs://baf..., https://opensea.io/assets/0x.../42, did:example:asset123.
Decentralized Identifier of the rights holder. Examples: did:key:z6Mk..., did:pkh:eip155:1:0x..., did:story:...
Optional additional parameters, e.g. {"rev_share_pct":10}. Leave as {} for none.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `certify_license_election`. Task: Bind a license election (family, id, params) to a named asset and licensor DID, producing a deterministic terms_hash via SHA-256 over the JCS-canonical election core.
Call it with arguments: {"policy_parameters":{}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
PII rule: All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only.
