## 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 tick-hugen-tokyo-90e31f6f
```

Example prompt: Show me all the FX currency pairs you have available for tick data, along with their current data quality state and how many sources are feeding each one.

## When to prefer this

Use this endpoint before subscribing to individual FX tick data streams to discover which instruments are available, how many sources back each one, and whether data quality is acceptable. It is the discovery/catalog step that complements the single-symbol and all-symbols tick endpoints on the same provider.

## Known failure modes

- Payment required (402) if USDC payment header not included
- No symbols returned if all sources are offline
- Stale quality states if data pipeline is degraded
- Network timeout if Tokyo endpoint is unreachable
