How this service works
Discover the current TickerLayer Indices symbol catalog. Stock symbols are market-qualified in COUNTRY_OR_MARKET:SYMBOL form such as US:AAPL.
Output
An array of index symbol objects, each containing a market-qualified symbol string in COUNTRY_OR_MARKET:SYMBOL format (e.g. US:SPX) and a human-readable name for the index.
Example use cases
Validating an index symbol before querying
“Before I fetch the price for this index, can you check if 'US:DJI' is a valid symbol in the TickerLayer indices catalog?”
Building a global index watchlist
“I want to set up a watchlist of global market indices — can you fetch all the available index symbols from TickerLayer so I can pick the ones I care about?”
Discovering country-specific index coverage
“Which market indices does TickerLayer cover for European markets? Pull the full indices symbol catalog so I can see what's available.”

Endpoint
GEThttps://x402.tickerlayer.com/v1/indices/symbolsWhen to prefer
Use this endpoint when you need to enumerate all supported index symbols before making downstream quote or data requests, or when you need to validate whether a specific index ticker exists in TickerLayer's coverage universe. Prefer this over the stocks, ETF, forex, commodities, or crypto sibling endpoints when the asset class is specifically a market index (e.g. S&P 500, Dow Jones, FTSE 100).
Side effects
- Payment failure (402) if the x402 payment of $0.02 USDC is not successfully processed
- Empty or incomplete symbol list if the catalog is temporarily unavailable
- Network timeout if the endpoint is under load
- Malformed response if API versioning changes
