## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tickerlayer-stocks-symbol-catalog-d466fa96
```

Example prompt: Can you pull the full list of stock symbols available on TickerLayer, including their market codes like US:AAPL, so I can see what equities I can query?

## When to prefer this

Use this endpoint when you need to discover or validate which stock symbols are supported by TickerLayer before making downstream data calls, or when building a symbol picker/autocomplete. Prefer this over the ETF, Indices, Forex, Commodities, or Crypto catalog endpoints when you specifically need equity/stock listings. This is the right choice when you need the market-qualified symbol format (e.g. US:AAPL) for use with other TickerLayer endpoints.

## Known failure modes

- Payment failure: x402 payment of $0.02 USDC not processed, returns 402 Payment Required
- Network timeout if the catalog is large and connection is slow
- Empty or partial response if the catalog is temporarily unavailable
- Rate limiting if too many requests are made in quick succession

## How this service works

Discover the current TickerLayer Stocks symbol catalog. Stock symbols are market-qualified in COUNTRY_OR_MARKET:SYMBOL form such as US:AAPL.

## Output

An array of stock symbol objects, each containing: the market-qualified symbol (e.g. US:AAPL), the unqualified base symbol (e.g. AAPL), the company or instrument name, and the market/country code (e.g. US). The catalog covers all equities currently supported by TickerLayer across all available markets.
