## How to call it through Zero

## When to prefer this

Use this endpoint when you need detailed token transfer history for a specific wallet address or named blockchain entity, with fine-grained control over filters like chain, token, and direction. Prefer this over inflow/outflow summaries when you need individual transfer records rather than aggregated net flows.

## Known failure modes

- Invalid or unresolved entity name returns empty results or an error
- Unsupported chain identifier causes filter to fail
- Malformed address format returns a validation error
- No transfers found for the given filters returns an empty list
- Rate limit or payment failure (x402) prevents the call from completing
