# getPreConfCoverage

> Get Preconfirmations coverage as a percentage of network stake and its distribution by region.

Use this method to get [Preconfirmations coverage](/docs/pre-confirmations/overview#coverage). The response includes network stake coverage and a regional breakdown.

## Endpoint

Send an HTTP POST request to the Helius [Gatekeeper](/docs/gatekeeper/overview) endpoint:

```text theme={"system"}
POST https://beta.helius-rpc.com/?api-key=YOUR_API_KEY
```

## Authorizations

<ParamField query="api-key" type="string" required>
  Your Helius API key, passed as the `api-key` query parameter.
</ParamField>

## Body

This method takes no parameters. Omit `params` from the request.

## Response

<ResponseField name="result.networkSharePercent" type="number">
  Percentage of total network stake covered by Helius and BAM.
</ResponseField>

<ResponseField name="result.coverageByRegion" type="object">
  Share of covered stake in each region. For example, `"fra": 0.27` means Frankfurt accounts for 27% of the covered stake.
</ResponseField>

<Note>
  Coverage is measured by stake, not by the percentage of transactions delivered.
  It covers both sources regardless of your subscription filters and does not
  guarantee a continuous stream. See [Coverage](/docs/pre-confirmations/overview#coverage).
</Note>
