# Resource Auditor

The resource provider that wishes to avail this service can select the auditor to verify the data before generating the `dataid`. The auditor can use the marketplace API to access the data that is to be verified.

The auditor can also choose to perform claim verification via trust anchors. Once the verification is complete, the party can proceed with other operations.

#### Marketplace API

Marketplace API can be used to fetch details regarding the data using the `orderId`. The auditor fixes the data verification result parameter.

```yaml
 {
    orderId: 'orderId',
    isCer: true,
  }
```

#### Trust Anchor Data Verification

For details, please refer to the claim issue section.

Once the verification process is completed, the marketplace automatically synchronizes the verification details.

## 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://docs.ont.io/decentralized-identity-and-data/ddxf/solutions/resource-auditor.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.
