# Bonds

Sovereign yield curves, index-level credit spreads and a bond-by-bond screener, in one section.

BlueGamma covers bonds through three tools. They answer different questions, so which one you want depends on whether you are looking at a sovereign curve, a credit index, or an individual security.

### The Three Tools

| Tool                                                                                                          | What it gives you                                                                                                                                    |

| [**Bond Comps**](https://www.bluegamma.io/documentation/market-data-guides/overview-2/bond-comps)             | A screener for individual bonds: yield, spread, rating, sector, tenor and amount outstanding, side by side                                           |

Each has its own page in this section, listed in the left-hand navigation under **Bonds**.

### Which One Do I Want?

{% endhint %}

### What They Share, and What They Don't

All three sit under **Bonds** in the left-hand navigation and export through **Download**.

The controls differ:

| Tool                 | Valuing at a past date                                                                                    |
| -------------------- | --------------------------------------------------------------------------------------------------------- |
| **Government Bonds** | **Valuation Date** selector                                                                               |
| **Bond Comps**       | **Change time**, with **LIVE DATA** to return to the current market                                       |
| **iBoxx Spreads**    | No past-date control. Current Spreads is live, and history is charted in the **Historical Spreads** panel |

### Where to Start

[**Accessing Bond Yields**](https://www.bluegamma.io/documentation/market-data-guides/overview-2/accessing-bond-yields) walks through finding a yield in each of the three, and is the quickest way in if you are new to the section. Questions that apply across all three are answered in the [**FAQs**](https://www.bluegamma.io/documentation/market-data-guides/overview-2/faqs).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://bluegamma.io/documentation/market-data-guides/overview-2.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
