```

Example prompt: Can you pull the top 20 crypto asset symbols that Mangrove tracks so I know which tickers I can query for prices or TVL data?

## When to prefer this

Use this endpoint when you need to discover or enumerate which crypto asset symbols are available on the Mangrove platform before making downstream calls for price, TVL, or market data. It is the right choice for populating dropdowns, validating tickers, or building symbol-aware queries against the Mangrove API suite.

## Known failure modes

- Invalid or non-integer top_n value returns a 400 validation error
- Exceeding rate limits or quota results in a 402 or 429 response
- Service unavailability returns a 503 error
- Empty result set if no symbols are currently indexed
