## 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 x402stock-ticker-types-lookup-0b604f7f
```

Example prompt: What are all the valid ticker types I can use when querying x402stock — like for filtering between stocks, ETFs, and other instrument categories?

## When to prefer this

Use this endpoint when you need to discover or validate the set of allowed ticker type values before constructing queries against other x402stock endpoints. It serves as a reference/metadata call to understand the classification taxonomy of the platform, especially useful when building agents that dynamically filter instruments by type.

## Known failure modes

- Payment failure if USDC balance is insufficient — returns 402 Payment Required
- Invalid properties filter parameter — may return 400 Bad Request or empty result
- Service unavailable — returns 5xx if upstream x402stock API is down
- No ticker types returned if the catalog is temporarily inaccessible
