# LunarLander routes

> Bifrost routes for HelloMoon Lunar Lander submit, bundle, and binary batch.

Send the body HelloMoon's [Lunar Lander reference](https://docs.hellomoon.io/reference/lunar-lander) defines. ThorNode supplies the upstream credential. The response body is Lunar Lander's, unchanged.

## Submit

```text theme={null}
POST /lunarlander
```

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sendTransaction",
  "params": ["<BASE64_SIGNED_TRANSACTION>", { "encoding": "base64" }]
}
```

Response: `{"jsonrpc":"2.0","id":1,"result":"<SIGNATURE>"}`.

## Bundle

Up to 4 transactions that land together or not at all.

```text theme={null}
POST /lunar-submit-bundle
```

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sendBundle",
  "params": [["<BASE64_SIGNED_TRANSACTION_1>", "<BASE64_SIGNED_TRANSACTION_2>"], { "encoding": "base64" }]
}
```

Response: `{"jsonrpc":"2.0","id":1,"result":"<BUNDLE_ID>"}`.

## Batch

Binary body, `content-type: application/octet-stream`. Concatenate up to 16 transactions, each as a big-endian 16-bit length followed by the raw transaction bytes:

```text theme={null}
[2 bytes: tx1 length][tx1 bytes][2 bytes: tx2 length][tx2 bytes]...
```

```text theme={null}
POST /lunar-submit-batch
```

Response:

```json theme={null}
{ "attempted": 2, "accepted": 2, "rejected": 0, "parse_error": null }
```
