range_resp = requests.get(f"{BASE}/range", params={"exchange": "pump_fun"}, headers={"X-API-Key": API_KEY})
print(range_resp.json())  # {"exchange": "pump_fun", "start": "...", "end": "...", "files": ...}


# Download a single hour
resp = requests.get(f"{BASE}/download", params={
    "exchange": "pump_fun",
    "date": "2026-08-16",
    "hour": "12"
}, headers={"X-API-Key": API_KEY})


with open("pump_fun_2026-08-16_12.parquet", "wb") as f:
    f.write(resp.content)


# Batch download: loop over hours
for hour in range(24):
    resp = requests.get(f"{BASE}/download", params={
        "exchange": "pump_fun",
        "date": "2026-08-16",
        "hour": str(hour)
    }, headers={"X-API-Key": API_KEY})
