# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://persona-mcp-server.onrender.com/ai/advisory" \
  -H 'content-type: application/json' \
  -d '{"classification_only": {"description": "true => simple classification (lowest tier $1)", "required": false, "type": "boolean"}, "has_source_docs": {"description": "true => source documents attached for cross-verification (raises tier)", "required": false, "type": "boolean"}, "question": {"description": "Korea-specific question/matter to judge", "required": true, "type": "string"}, "title": {"description": "Short subject (optional)", "required": false, "type": "string"}}'

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
