curl -i -X POST "https://mesh.heurist.xyz/x402/agents/YahooFinanceAgent/fetch_price_history" \
  -H 'content-type: application/json' \
  -d '{"debug": {"default": false, "description": "Debug mode flag.

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