Sister project to Anubis

This project came about due to a lack of free and open APIs for subdomain enumeration.

There is only one endpoint - https://anubisdb.com/anubis/subdomains/:domain, where :domain is the domain.

GET returns the full list of known subdomains for the domain. POST stores valid submitted subdomains and returns counts only; it does not return the full stored subdomain list. Use GET after POST if you need the current full list.

A sample AJAX GET request looks like:

fetch("https://anubisdb.com/subdomains/reddit.com", {
  method: "GET",
  headers: {
    "Content-Type": "application/json",
  },
})
  .then((response) => response.json())
  .then((data) => {
    // Handle data here
    console.log(data);
  })
  .catch((error) => {
    // Handle error here
    console.error("Error:", error);
  });

A sample AJAX POST request looks like:

fetch("https://anubisdb.com/subdomains/reddit.com", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    subdomains: ["www.reddit.com", "old.reddit.com"],
  }),
})
  .then((response) => response.json())
  .then((data) => {
    // {
    //   domain: "reddit.com",
    //   created: false,
    //   acceptedSubdomainCount: 2,
    //   insertedSubdomainCount: 1
    // }
    console.log(data);
  })
  .catch((error) => {
    console.error("Error:", error);
  });

You're limited to 60 requests per 10 seconds per source IP. This is enforced at Cloudflare's edge before requests reach the Worker.

There is also a 10,000 subdomain limit per domain.

This service runs as a Cloudflare Worker backed by the anubis-db D1 database.

Useful commands:

yarn dev
yarn db:migrate:local
yarn db:migrate:remote
yarn migrate:postgres
yarn deploy

yarn migrate:postgres reads the source PostgreSQL URL from DB_URL or SOURCE_DB_URL, generates D1-compatible SQL chunks in .d1-import, and applies them to the remote D1 database with Wrangler. Keep CLOUDFLARE_API_TOKEN in the shell environment when running remote D1 or deploy commands.

The most straightforward way of contributing is just to use Anubis and have it sends its results to AnubisDB.

Contributions to AnubisDB are always appreciated, as well. Currently parsing and over-use protections are lacking. Take a look at the issues and see if there is anything that you'd like to contribute to.
