Agent-native paid utility · v0.4.3

Check explicit assertions over synthetic JSON you supply.

Start with synthetic JSON, inspect the free precheck and quote, and authorize paid execution separately only if needed. A passing deterministic assertion does not prove real-world truth.

available

Free decision support

Request validation, capability description, recipes, quotes, and purchase preparation. POST https://agent-economy.kgninja.dev/validate-request returns an unsigned precheck receipt with a canonical request hash, checked discovery contracts, the canonical MCP card hash, A2A fields, a configured x402 baseline, unpaid status, policy version, and evidence-discard metadata without creating a quote, requesting payment, executing assertions, or calling the private Verification Core.

Paid verification

Deterministic assertion execution, Ed25519-signed evidence, a delivery receipt, and the x402 settlement response. Payment remains the calling agent's policy decision.

Use with ChatGPT

Open this page in Chrome and use the official ChatGPT extension side chat to ask about the page. Page context is not payment approval. The extension does not automatically connect an MCP service or provide a payment wallet. WebMCP site tools are currently limited to the ChatGPT desktop built-in browser, not the Chrome extension. If a browser, HTTP tool or wallet is unavailable, explain the missing capability and stop there.

Copy a prompt below for explanation or free conditions checking only.

Explain this AVU page using only the synthetic JSON-check use case. Separate free precheck/quote from paid assertion execution and explain what a passing result cannot prove. Do not purchase, sign, connect a wallet or change settings.
Read AVU's free metadata and explain how to validate {"synthetic":true,"value":42}. Use only free precheck and quote operations if an authorized HTTP tool is available; otherwise show the missing capability. Report price cap, asset, network, payee, binding and expiry, then stop before signing or payment. Send no secrets.

Technical knowledge base

Product scope: syntactic and deterministic assertion execution over supplied JSON. A passing result is not proof that a real-world claim is true.
