## Swaps by wallet — GET `/v1/trades`

Every swap a wallet sent (or a pool’s, a token’s), newest first, filterable by token, side, size and time.

Layers: Elysium, HyperEVM. Not on HyperCore: swap history is EVM only; a HyperCore account's fills: POST /info userFills (Hyperliquid-compatible).
Page with live calls: https://femtos.xyz/reference/wallet-trades?layer=<elysium|hyperevm>

| Param | In | Example or values | Meaning |
|---|---|---|---|
| `layer` | query | `elysium` (Elysium); `hyperevm` (HyperEVM) | Layer |
| `trader` | query | `<creator>` (Elysium); `<evmWallet>` (HyperEVM) | History of a wallet (tx.from of the swaps); a named wallet's handle works too |
| `token` | query | (optional) | Swaps where this token is base or quote |
| `side` | query | `(empty)`, `buy`, `sell` | Buys or sells of the base |
| `minUsd` | query | (optional) | Smallest USD value (the indexer's, at the swap) |
| `limit` | query | `20` | Rows |
| `cursor` | query | (optional) | Next page: `next_cursor` of the previous answer |

Elysium:

```bash
curl -H "Authorization: Bearer $FEMTOS_KEY" "https://api.femtos.xyz/v1/trades?layer=elysium&trader=<creator>&limit=20"
```

HyperEVM:

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

| Field | Type | Meaning |
|---|---|---|
| `rows[]` | object | Newest first: {t, block, tx, logIndex, id, pair, protocol, base, quote, baseAddress, quoteAddress, side, …} |
| `coverage` | all \| priced | priced: a token of more than 20 pools, read through its priced swaps only (volume_usd set) |
| `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).
