Cloudflare Trace

Overview

Cloudflare Trace returns your connection’s view from Cloudflare’s edge — your public IP, location (country/city/colo), TLS details, and more — as plain text from the /cdn-cgi/trace endpoint on any Cloudflare-served site. Keyless, CORS-friendly, and a handy way to get your own public IP without a dedicated IP API.

Note (verified 2026-08): the listing’s mirror endpoint (cloudflare-trace.fawazahmed0.workers.dev) returns HTTP 404 — the workers.dev deployment is gone. The official Cloudflare endpoint works (verified live).

Quick Start

Official endpoint (verified live):

curl "https://www.cloudflare.com/cdn-cgi/trace"

fl=574f50
h=www.cloudflare.com
ip=210.61.187.110
ts=1787377422.000
visit_scheme=https
uag=curl/8.14.1
colo=KHH
loc=TW
tls=TLSv1.3
sni=plaintext
warp=off
gateway=off
rbi=off

Any Cloudflare-served site works:

curl "https://example.com/cdn-cgi/trace"   # if the site uses Cloudflare

Authentication

None — keyless.

Rate Limits & Notes

• Free; it’s an edge service, no documented hard limit.
• Returns plain-text key/value lines: ip (your public IP), loc (country code), colo (edge city), tls (TLS version), h (host), uag (user agent).
• The mirror workers.dev endpoint is dead (404) — use the official /cdn-cgi/trace path.
• Great as a zero-dependency IP + connection-info source.

FAQ

Is Cloudflare Trace free? Yes — free and keyless.

Why does the listed URL 404? The community mirror (cloudflare-trace.fawazahmed0.workers.dev) is offline — use any Cloudflare site’s /cdn-cgi/trace.

What info does it give? Your public IP, location, TLS details, and Cloudflare edge info.
