## Completed sBTC deposits

`GET /v1/index/sbtc/deposits`

Completed deposits, one row per `completed-deposit` event, oldest first. The event fires once the signers have swept the BTC in, so every row is final on the peg side. With no cursor or `from_height`, the read covers the last day.

### Filters

| Name | Type | Description |
| --- | --- | --- |
| `sender` | string | Stacks principal on the event. Exact match. Mainnet deposits currently carry none. |
| `bitcoin_txid` | string | Deposit's Bitcoin txid, `0x`-prefixed hex. Exact match. |

### Range and paging

| Name | Type | Description |
| --- | --- | --- |
| `limit` | integer · 1 to 1000 | Page size; capped at 1000. |
| `cursor` | string | `<block_height>:<event_index>` from a previous page's `next_cursor`. Resumes after it. |
| `from_cursor` | string | Same as `cursor`. Mutually exclusive with it and with `from_height`. |
| `from_height` | integer | First block height to read. Mutually exclusive with a cursor. With neither, the read starts one day behind the tip. |
| `to_height` | integer | Last block height to read, inclusive. |
| `confirmed` | boolean | `true` stops the page at the finality boundary, so every row is past the reorg margin. |
| `fields` | string | Comma-separated columns to return, from: `block_time`, `tx_id`, `tx_index`, `event_index`, `amount`, `sender`, `bitcoin_txid`, `output_index`, `recipient_btc_version`, `recipient_btc_hashbytes`. `cursor` and `block_height` always come back; an unknown name is refused. |

### Returns

A cursor envelope; `deposits` holds `SbtcDeposit` objects.

### Responses

- `200` Cursor-paginated envelope
- `304` The page is past finality and matches your `If-None-Match` ETag.
- `400` A parameter, filter, cursor or body field was refused; `code` says which
- `401` This bind requires the instance token, and it was missing or wrong
- `429` Rate limited; retry after `Retry-After` seconds
