Input your merchant profile — platform, buyer type, AOV, agent-traffic appetite — to get a ranked protocol decision matrix across UCP, ACP, x402, and Visa TAP/VIC with a ready-to-wire stack recommendation. Outputs a §4 hash-anchored OpenChainGraph artifact.
| Protocol | Your Platform | Your Buyer Type | Your AOV Range | Agent-Ready |
|---|
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 `select_agentic_checkout_protocol`. Task: Score ACP, UCP, x402, and Visa TAP against platform profile (buyer type, AOV, geography, stack capabilities) and returns a ranked protocol recommendation with fit scores.
Call it with arguments: {"policy_parameters":{"platform":"custom","buyer_type":"agent","aov":"mid","agent_appetite":"high","geo":"global","tech_cap":"api","stack_card":false,"stack_crypto":false}}
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.
Open the tool with the sample prefilled: https://ainumbers.co/chaingraph/art-19-agentic-checkout-protocol-selector.html#p=v1.H4sIAAAAAAAA_wGWAGn_eyJwbGF0Zm9ybSI6ImN1c3RvbSIsImJ1eWVyX3R5cGUiOiJhZ2VudCIsImFvdiI6Im1pZCIsImFnZW50X2FwcGV0aXRlIjoiaGlnaCIsImdlbyI6Imdsb2JhbCIsInRlY2hfY2FwIjoiYXBpIiwic3RhY2tfY2FyZCI6ZmFsc2UsInN0YWNrX2NyeXB0byI6ZmFsc2V9YddB_5YAAAA
