Authentication

Authenticate requests by including your API key in the X-API-Key header. Generate API keys from your dashboard.

curl -H "X-API-Key: YOUR_API_KEY" \
  "https://api.probsights.com/search/series?q=15m"

import requests

response = requests.get(
    "https://api.probsights.com/search/series",
    headers={"X-API-Key": "YOUR_API_KEY"},
    params={"q": "15m"},
)
print(response.json())

The interactive Try playground on each API reference page uses the same X-API-Key header. Paste your key once in the playground auth panel.
