## How to call it through Zero

## When to prefer this

Choose this endpoint when you need quick, no-signup, pay-per-call stock price lookups for AI agents operating autonomously with a USDC wallet on Base. It is ideal for agents that need occasional equity price data without committing to a subscription or managing API keys — the x402 micropayment acts as both authentication and billing. Best for low-to-moderate frequency lookups where $0.003/call economics make sense.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty data
- Payment failure or insufficient USDC balance results in a 402 response blocking the call
- Network or Cloudflare Worker downtime may cause 5xx errors
- Market closed hours may return last closing price rather than a live quote
- Missing or malformed schema parameter may cause a 400 bad request
