## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability api-the402-ai-330b9092 -d '<json body>'
```

Example prompt: Pull the current stock price and basic market data for AAPL using the402.ai — pay the $0.005 USDC fee automatically.

## When to prefer this

Choose this endpoint when you need on-demand stock market data and are operating in an AI agent context with x402 micropayment capability. Ideal for agents that need financial data without a traditional API subscription, paying only per-use at $0.005 USDC. Best when integrated into agentic workflows that already handle x402 payment headers.

## Known failure modes

- Insufficient USDC balance causing payment failure
- Invalid or unrecognized ticker symbol returns error
- Payment facilitator unavailable or timeout
- Rate limiting if too many requests made in quick succession
- Market closed or data unavailable for requested time period

## Output
