# Bundle Trace

The **Bundle-Trace** service allows users to check the status of a submitted bundle — whether it was included on-chain, or how it behaved within bloXroute’s internal system.

It provides detailed insights including the bundle hash, block number, simulation results, and visibility across bloXroute and external builders.

Bundle-Trace limits requests to **1 request every 30 seconds** and **4 requests per day**.

[Purchase the **Bundle Trace Add-on**](https://portal.bloxroute.com/pricing) to increase the limit to **60 requests per day** for this endpoint.

## Submission Endpoint

* Method: `ethbundletrace`
* Endpoint: `https://tools.bloxroute.com`

### Parameters

<table><thead><tr><th>Name</th><th width="248.33333333333331">Description</th></tr></thead><tbody><tr><td><code>auth_header</code></td><td><p>Allows the user to include the authentication in the URL string directly.</p><p>If the authentication is provided in both the header and the URL parameter, the one in the header will be used.</p></td></tr><tr><td><code>block_number</code></td><td>[Optional]Allows the user to specify the block number they sent the bundle to.<br>In case the bundle was sent to multiple blocks - this parameter is mandatory</td></tr></tbody></table>

#### **Examples**

**Option 1 – curl Command :**

```bash
curl -X GET \
-H "Content-Type: application/json" \
-H "Authorization: <YOUR-AUTHORIZATION-HEADER>" \
https://tools.bloxroute.com/ethbundletrace/<BUNDLE_HASH>
```

**Option 2 – URL with Query Param:**

```
https://tools.bloxroute.com/ethbundletrace/<BUNDLE_HASH>?auth_header=<AUTH_HEADER>
```

#### **Response Fields**

| Field             | Description                                   |
| ----------------- | --------------------------------------------- |
| `bundle_hash`     | Hash of the submitted bundle.                 |
| `on_chain_status` | Whether the bundle was included on-chain.     |
| `block_number`    | Block number the bundle was targeted for.     |
| `bloXroute`       | Internal trace details (see breakdown below). |

#### **bloXroute Field Breakdown**

| Detail                             | Explanation                                                              |
| ---------------------------------- | ------------------------------------------------------------------------ |
| Receive time                       | Time when bloXroute first received the bundle.                           |
| Initial simulation                 | Outcome of the initial bundle simulation (e.g., success, nonce error).   |
| Effective gas price                | Measured gas price of the bundle.                                        |
| First inclusion in bloXroute block | Timestamp of first inclusion in bloXroute-simulated blocks.              |
| Inclusion %                        | Percentage of blocks where the bundle was included.                      |
| Rejection reason                   | Reason for non-inclusion in our block (e.g., higher-paying bundles).     |
| Final simulation error %           | Percentage of how many blocks the bundle had final simulation errors in. |
