## When to prefer this

Use this endpoint when you need concise, real-time US equity fundamentals (market cap, PER, ROE, EPS, quarterly financials, latest close) for a specific NASDAQ or NYSE ticker. Prefer this over full historical endpoints when a snapshot of current metrics suffices. Best for quick valuation checks, stock screening, or enriching agent workflows with live US stock data at low per-call cost ($0.05 USDC).

## Known failure modes

- Invalid or non-US ticker symbol returns an error or empty result
- Ticker listed on neither NASDAQ nor NYSE will fail to resolve
- If exchange is specified incorrectly for a ticker, lookup may fail
- Data may lag for thinly traded or recently listed companies
- Payment failure (insufficient USDC balance) returns 402 Payment Required

## How this service works

US stock company pack ($0.05 USDC). Fundamentals for NASDAQ/NYSE-listed companies: market cap, PER, ROE, EPS, latest quarterly financials (USD), and latest close. Ticker is the US symbol (e.g. AAPL, NVDA, TSM, SKHY). Exchange auto-resolved (NASDAQ first, then NYSE) or force with ?exchange=.

## Output
