## Developer quickstart
Build and Backtest with the most trusted & comprehensive Tokenomics API.
```python Python theme={null}
import requests
url = "https://api.tokenomist.ai/v4/token/list"
headers = {"x-api-key": "YOUR_API_KEY"}
response = requests.get(url, headers=headers)
tokens = response.json()["data"]
for token in tokens[:5]:
print(token["name"], token["circulatingSupply"])
```
```typescript TypeScript theme={null}
const response = await fetch(
"https://api.tokenomist.ai/v4/token/list",
{ headers: { "x-api-key": "YOUR_API_KEY" } }
);
const { data: tokens } = await response.json();
tokens.slice(0, 5).forEach((token) => {
console.log(token.name, token.circulatingSupply);
});
```
