## When to prefer this

Choose this endpoint when you need Yahoo Finance market or stock data via a pay-per-call model on Base chain using x402 micropayments, and you want to avoid subscription-based finance APIs. Best for agents that already handle x402 payment flows and need on-demand financial lookups without a standing API key.

## Known failure modes

- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Invalid or missing ticker/query in request body — returns error or empty result
- Yahoo Finance rate limiting or data unavailability — returns error in result object
- Network timeout to underlying Yahoo Finance data source
- Malformed request body — returns 400 or validation error
