# Create Blockchain API for your project

## Blockchain API Endpoint

JSON-RPC Endpoint

```
http://api.chainup.net/<PROTOCOL>/<NETWORK>/<TOKEN>
```

Websocket Endpoint

```
ws://api.chainup.net/ws/<PROTOCOL>/<NETWORK>/<TOKEN>
```

## Using a token example&#x20;

Ethereum APIs require a valid project ID to be included with your request traffic. This identifier must be appended to the request URL. The following example shows how to do this for HTTPS or WebSocket requests:

{% tabs %}
{% tab title="HTTP" %}

```
curl http://api.chainup.net/ethereum/mainet/<TOKEN> \
    -X POST \
    -H "Content-Type: application/json" \
    -H "CONSISTENT-HASH: true" \
    -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
```

{% endtab %}

{% tab title="WebSocket" %}

```
wscat -c ws://api.chainup.net/ws/ethereum/mainet/<TOKEN>
> {"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}
```

{% endtab %}
{% endtabs %}

## Using a token example for Solana (Low latency domain)

When accessing solana you can use proprietary domain names to reduce network latency

{% tabs %}
{% tab title="HTTP" %}

```
curl http://sol.chainup.net/<TOKEN> \
    -X POST \
    -H "Content-Type: application/json" \
    -d '{"jsonrpc":"2.0","id":1, "method":"getSlot"}'
```

{% endtab %}

{% tab title="WebSocket" %}

```
wscat -c ws://sol.chainup.net/ws/<TOKEN>
> { "jsonrpc": "2.0", "id": 1, "method": "slotSubscribe"}
```

{% endtab %}
{% endtabs %}

# Agent Instructions: 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:

```
GET https://docs.chainupcloud.com/blockchain-api/overview/create-blockchain-api-for-your-project.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
