Getting an API key

While signed in, POST to /api/keys/register (or use Register free API key in Studio).
Click the confirmation link in the email (key activates once).

Python snippet

Minimal example using requests:

import os
import requests

BASE = "https://YOUR_DOMAIN"
API_KEY = os.environ.get("CATALITIUM_API_KEY", "cat_XXXXXXXXXXXXXXXXXXXXXXXX")

resp = requests.get(
    f"{BASE}/v1/jobs",
    params={"title": "ai engineer", "country": "US"},
    headers={"X-API-Key": API_KEY},
    timeout=10,
)
resp.raise_for_status()
data = resp.json()
print("Found", data["meta"]["total"], "jobs")

Limits & headers

Quotas combine daily and calendar-month limits (see API reference). Each response includes:

X-RateLimit-Limit / Remaining for the daily window.
X-RateLimit-Reset, next daily reset (UTC).
X-RateLimit-Window is daily; monthly totals are in GET /api/keys/usage.
