# Name

Names are at the heart of every contact record—yet they're often incomplete, misspelled, or reversed. Delpha's **Name Validator** helps you detect, normalize, and correct person names to ensure consistent, high-quality identity data across your systems.

Each input is evaluated through several smart checks:

* **Completeness:** Measures whether both *first name* and *last name* are present, returning individual scores for each.
* **Validity:** Confirms if the given names exist in trusted linguistic databases.
* **Consistency:** Compares the original input to its normalized form (capitalization, spacing, hyphenation, etc.).
* **Misspelled:** Detects potential typos and suggests the closest valid alternatives.
* **Reversed:** Identifies when *first name* and *last name* appear swapped based on statistical likelihoods.

The API returns a **normalized version** of the name, along with these detailed quality indicators. When needed, it also proposes gentle corrections—like fixing a misspelling or switching first and last names—always preserving the user's intended identity.

With **Name Validator**, your contact data stays clean, standardized, and ready for reliable engagement.

## 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://help.delpha.io/delpha-api-and-mcp/api/name.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.
