Earnings day monitoring
“Check the current price and percent change for META — I want to see how the market is reacting after their earnings report.”
Technical details
Endpoint
POSThttps://x402deploy.vercel.app/api/stockWhen to prefer
Choose this endpoint when you need a quick, no-auth stock quote for any major US-listed ticker and are already set up for x402 micropayments. At $0.005 USDC per call it is cost-effective for occasional lookups or agent workflows that need on-demand price checks without maintaining API keys for a dedicated financial data provider.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty result
- Market closed state may affect availability of real-time prices vs delayed quotes
- Payment failure via x402 (insufficient USDC balance or facilitator issue) blocks the request
- Network timeout on the upstream data provider returns a 5xx error
- Missing required 'symbol' field in request body returns a 400 validation error
