myconf.it API

Public, no-auth JSON endpoints for the free tools on myconf.it. Designed for shell scripts, monitoring jobs, LLM agents and anything that prefers structured output to scraping HTML.

// live endpoints

GET /api/ip

Caller IP (IPv4 / IPv6), geolocation, ASN, HTTP headers.

curl https://myconf.it/api/ip
curl -H 'Accept: text/markdown' https://myconf.it/api/ip
curl https://myconf.it/api/ip.md

Use case: replace ifconfig.me / icanhazip with a tool that gives you geo + headers in one shot.

GET /api/subnet?ip=<ipv4>&cidr=<0-32>

Full IPv4 subnet calculation: network, broadcast, hosts, masks, binary, class, type.

curl 'https://myconf.it/api/subnet?ip=192.168.1.0&cidr=24'
curl 'https://myconf.it/api/subnet?ip=10.0.0.0&mask=255.255.255.224'
curl 'https://myconf.it/api/subnet.md?ip=172.16.0.0&cidr=20'

Accepts cidr (0–32) or mask (dotted decimal).

// planned

GET /api/geo?ip=<ip>

Geolocate an arbitrary IP. Registered users.

GET /api/email?domain=<domain>

SPF / DKIM / DMARC / blacklist report. Registered users.

Response envelope

All endpoints return a uniform JSON envelope so agents and LLMs can parse responses without knowing the specifics of each tool. The explanation field is a human-readable summary intended for LLMs that need to translate the result for an end user.

  "version": "1.0",

}

CORS, auth, rate limits

All endpoints respond with Access-Control-Allow-Origin: * and require no authentication. They are safe to call from browsers, server-side agents and LLM tool calls. Reasonable use is welcome; abusive traffic is rate-limited at the edge by Cloudflare. Premium endpoints (geo lookup for arbitrary IPs, deliverability checks) will require a free account.
