Example

Send your API key in the X-API-Key header (recommended) or as the api-key query parameter. Examples below use the header.

import requests

resp = requests.get(
    "https://kwery-api.com/v1/symbols",
    headers={"X-API-Key": "YOUR_KEY"},
)
data = resp.json()
for sym in data.get("symbols", []):
    print(f"{sym['symbol']}: {sym['sources']}")

Query parameter alternative: Add api-key=YOUR_KEY to the URL for quick tests; the header is recommended for production.
