## When to prefer this

Choose this endpoint when you need ETF market data without a traditional API key, want per-call USDC micropayment billing on Base or Solana, or are operating in an agentic/autonomous context where key management is impractical.

## Known failure modes

- Missing or invalid symbol parameter returns an error
- Payment not settled results in 402 response
- Unknown or delisted ETF symbol may return empty or error response
- Network or gateway downtime causes timeout or 5xx error

## Output
