First, you need to register for an account on CoinMarketCap and obtain an API key. This key will allow you to make requests to CoinMarketCap's API. Once registered, navigate to the API section of your account to generate and copy your API key.

Use a programming language like Python to make API requests. Install the `requests` library if needed. Write a script to send a GET request to the CoinMarketCap API endpoint (e.g., `/v1/cryptocurrency/listings/latest`). Include your API key in the request headers to authenticate. Parse and store the JSON response data.

Example in Python:
```python
import requests
headers = {'X-CMC_PRO_API_KEY': 'your_api_key'}
response = requests.get('https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest', headers=headers)
data = response.json()
```

Convert the fetched data into a format suitable for Weaviate. Weaviate expects data to be structured into classes and properties. Define a schema that represents the data structure. Map CoinMarketCap data fields to Weaviate classes and properties.

Example structure:
```json
{
"class": "Cryptocurrency",
"properties": [
{"name": "name", "dataType": ["string"]},
{"name": "symbol", "dataType": ["string"]},
{"name": "price", "dataType": ["number"]}
]
}
```

Install and set up Weaviate. This can be done locally using Docker or on a cloud service. Ensure Weaviate is running and accessible. You may need to configure network settings or ports if running locally.

Example Docker command:
```bash
docker run -d -p 8080:8080 semitechnologies/weaviate:latest
```

Use Weaviate’s RESTful API to define the schema. Send a POST request to `/v1/schema` with the schema JSON you prepared. This sets up the necessary classes and properties in Weaviate to store your data.

Example in Python:
```python
import json
schema = {
"classes": [{
"class": "Cryptocurrency",
"properties": [
{"name": "name", "dataType": ["string"]},
{"name": "symbol", "dataType": ["string"]},
{"name": "price", "dataType": ["number"]}
]
}]
}
response = requests.post('http://localhost:8080/v1/schema', json=schema)
```

Iterate over the CoinMarketCap data and transform each entry to match the Weaviate schema. Use Weaviate’s RESTful API to upload data by sending POST requests to `/v1/objects`.

Example in Python:
```python
for crypto in data['data']:
obj = {
"class": "Cryptocurrency",
"properties": {
"name": crypto['name'],
"symbol": crypto['symbol'],
"price": crypto['quote']['USD']['price']
}
}
response = requests.post('http://localhost:8080/v1/objects', json=obj)
```

After loading the data, query Weaviate to ensure the data has been correctly imported. Use Weaviate’s GraphQL interface to fetch and verify data matches your expectations. This step ensures that the data is both complete and accurate.

Example query:
```python
query = """
{
Get {
Cryptocurrency {
name
symbol
price
}
}
}
"""
response = requests.post('http://localhost:8080/v1/graphql', json={'query': query})
print(response.json())
```

This guide provides a direct and practical approach to moving data from CoinMarketCap to Weaviate using native capabilities and basic programming techniques.
