Example prompt: Can you pull up the full list of commodity symbols available on TickerLayer so I know which tickers I can use for pricing queries?

## When to prefer this

Use this endpoint when you need to enumerate all available commodity symbols on TickerLayer before making downstream price or market-status queries. Prefer this over the stocks, ETF, forex, crypto, or indices symbol endpoints when your domain of interest is physical or futures-based commodities (e.g. gold, oil, natural gas, agricultural goods).

## Known failure modes

- Payment failure (402): x402 micropayment of $0.02 USDC not completed or rejected
- Network timeout if TickerLayer catalog endpoint is temporarily unavailable
- Empty or malformed symbol list if catalog is being updated
- Authentication/payment header missing, resulting in 402 response
