| Param | In | Example or values | Meaning |
|---|---|---|---|
| `layer` | query | `hyperevm` | EVM layer |
| `address` | query | `<evmWallet>` | Transfers from / to this address (a named wallet's handle works too); token then optional |

```bash
curl -H "Authorization: Bearer $FEMTOS_KEY" "https://api.femtos.xyz/v1/transfers?layer=hyperevm&address=<evmWallet>&direction=any&limit=20"
```

| Field | Type | Meaning |
|---|---|---|
| `rows[]` | object | Newest first: {block, t, tx, logIndex, token, symbol, decimals, from, to, direction, amount, amountRaw, …} |
| `usdBasis` | current_price \| null | What usd / minUsd value the transfers at |
| `fromBlock` | int | First block of the window |
| `toBlock` | int | Last block of the window |
| `scanned` | int | Index rows read for this page (filters apply to them: at most 1000 per source per call) |
| `spamHidden` | int | Rows of spam tokens left out (includeSpam=true shows them) |
| `next_cursor` | string \| null | Opaque cursor of the next page; null when nothing is left in the window. A filtered page can hold fewer rows than limit, even none: keep paging while next_cursor is not null |

Next page: `cursor` = the `next_cursor` of the previous answer (https://femtos.xyz/agents.md#pagination).
