https://api.ismalicious.com/check/stream?query=example.com (or /stream?query=...). Same auth as GET /check (X-API-KEY Base64 or session).

What is each SSE message?

JSON lines like {"type":"reputation","data":{...}}. Phases include reputation, basic, insights, optional dns, enrichment, then done.

Can I stream file hashes?

No. The API returns 400 if the target looks like a hash; use GET /check for hashes.

The public progressive API is SSE-only. Use curl -N or EventSource in the browser.
