How to call it
A starting template for Portscan. Replace ENDPOINT with the path from the official documentation, which we link above rather than guess at.
# No authentication required.
curl -s "https://api.portscan.com/ENDPOINT" \
-H "Accept: application/json"This API does not send CORS headers, so a browser will block a direct call from your front end. Call it from your server, or put a small proxy in front of it.

Portscan — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Portscan free to use?
Portscan is listed in our free catalogue and required no credential when we called it. It needs no authentication at all, so you can send a request without signing up. Free tiers can still carry rate limits or non-commercial terms, so check the provider's own terms before shipping.
Does Portscan need an API key?
No. We called Portscan on 2026-09-18 with no key, no token and no Authorization header, and it responded. That is what puts it in our no-key collection.
Can I call Portscan from browser JavaScript?
Not directly. Portscan did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is Portscan still working?
Not at our last check on 2026-09-18. Portscan did not respond successfully, which is why it is marked as down here. This may be temporary; we re-check on a schedule and the badge above reflects the most recent run.
Is Portscan available over HTTPS?
Yes. Portscan serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
