## 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 2s-io-stock-symbol-search-8c4800dd
```

Example prompt: What's the ticker symbol for Palantir on the US exchange? I want to know its FIGI and security type too.

## When to prefer this

Use this endpoint when you need to resolve a human-readable company name to a machine-usable ticker symbol, enumerate all tradable instruments on a given exchange, or retrieve standardized identifiers (MIC, FIGI) for a security. Prefer over general web search when you need structured, exchange-authoritative data rather than approximate results.

## Known failure modes

- No results returned if query string matches nothing in the exchange
- Invalid exchange code returns empty or error response
- Limit parameter too large may cause timeout or truncated results
- Ambiguous company names may return many unrelated results requiring further filtering

## How this service works

Search or list the tradable equity symbol universe for an exchange. Pass q to substring-match on symbol or company name (case-insensitive), and/or exchange (default US) and limit. Returns matching listings with symbol, display symbol, description (company name), security type (e.g. Common Stock, ETF), currency, MIC, and FIGI. Use it to resolve a name to a ticker or enumerate a market. Data by Finnhub.

## Output

A list of matching securities, each with symbol, display symbol, company/description name, security type (e.g. Common Stock, ETF), currency, MIC (market identifier code), and FIGI (Financial Instrument Global Identifier).
