Getting started

Public utility endpoints such as time, IP address and exchange rates are free and require no authentication.

The DNS Management API at /v1 requires a Bearer token from Account → API keys. A token can access only its owner’s verified zones.

Public endpoint

fetch('https://api.c.nf/v1/public/time')
  .then(response => response.json())
  .then(data => console.log(data.data.iso8601));

Authenticated DNS v1 endpoint

fetch('https://api.c.nf/v1/dns/zones', {
  headers: { 'Authorization': 'Bearer cnf_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' }
})
  .then(r => r.json())
  .then(data => console.log(data.data.zones));

For AI agents

Point an agent at /v1/ai for a brief written to be pasted straight into a prompt, or at /v1/ai?format=json for the same endpoints as tool definitions. /v1/openapi.json is the full OpenAPI 3.1 contract, and /llms.txt is the crawler map. All four are generated from the same route table as this page, so none of them can describe an endpoint that does not exist.
