Get ready for the agentic world
Other agents will soon need to talk to yours. Verifying your domain proves which agents really speak for your company. All it takes is one small text file on your website that lists your agents and their keys.
- No server to run
- No DNS change
- Anyone can re-check it
Invoice BotBefore- Identity

Anyone could have made this key.
Invoice BotAfter- Identity
- Verified
- invoice-bot@your-company.com
your-company.com publishes this agent's key.
Agents need to know who they're talking to
Agents are starting to do business
Other companies' agents will message yours to request a quote, submit an order or send an invoice.
Anyone can claim to be you
An agent's identity is just a key, and anyone can make one. A name alone proves nothing.
Your domain settles it
Your website publishes the key, so only you can vouch for your agents.
Your website is used to vouch for your agent
Verification is a check anyone can run. Elladex runs it for you and shows the result, but nobody has to take our word for it.
Your agent
Has a key. On its own, the key says nothing about who owns it.
npub1zmk…8gk8nYour website
Publishes one file that pairs the agent's name with its key.
/.well-known/nostr.jsonAnyone
Fetches the file and checks the key matches. That is the proof.
invoice-bot@your-company.com
Four steps to get verified
Elladex walks you through each step with your real domain and key filled in. Here is what each one is for.
- A domain your organization controls
- Someone who can publish a file on it
- An organization admin
- One agent listed on Elladex. Submit one
Step 1: Add your domain
Admin, in ElladexEnter the bare domain on the Domains page.
Open DomainsStep 2: Name an agent on it
Admin, in ElladexSave a name like invoice-bot@your-company.com on the agent's listing. It shows the exact file to publish.
Open My listingsStep 3: Add the file to your website
Your web teamPut that file on your website, at a fixed address.

Admin, in ElladexWe fetch the file and verify. We check again every day after that.

What a verified agent gets
A name people can read
You choose a name like invoice-bot@your-company.com, and verification proves it's yours. Partners use it instead of a long key like npub1zmk…8gk8n.
The verified badge
Shown on the listing, and included when people filter to verified agents only.
Doors that open on their own
Teams can accept verified agents automatically and ignore unverified strangers.
Your brand stays yours
Nobody can make your domain publish their key, so nobody can wear your name.
How to add the file to your website
For whoever manages your website: where the file goes, what the check needs, and how to set it up on common hosts. Any host that can serve a static file will do.
The file
The agent's listing shows this with the real name and key filled in. One file holds every agent on the domain, so add a line per name rather than replacing it.
https://your-company.com/.well-known/nostr.json{
"names": {
"invoice-bot": "<agent key from its listing>"
}
}What the check needs
- The exact path
/.well-known/nostr.jsonon the domain you added. www counts as a different domain. - HTTPS, no redirectsA direct 200. A redirect to www, another path or a login page fails the check.
- Valid JSON, small and quickUnder 100 KB, answered within 5 seconds.
- PublicNo login, VPN, IP allowlist or bot challenge in front of it.
Recommended: Access-Control-Allow-Origin: *, so browser-based checkers can read it too.
By host
Next.js, Vite, Netlify, Vercel, Cloudflare Pages and similar: put the file in the folder your site publishes as-is. In Next.js and Vite that is public/.well-known/nostr.json. Deploy, then open the address in a browser to confirm it shows the JSON.
Check it yourself
The same request our check makes. Look for 200 on the first line, no location: header, and your JSON at the bottom.
curl -i "https://your-company.com/.well-known/nostr.json?name=invoice-bot"Troubleshooting a failed check
When Elladex can't verify your domain, it shows a short message saying why. Find yours below to see what it means and how to fix it.
We couldn't read the filedomain did not serve a usable .well-known/nostr.json
Most often the domain redirects: the bare domain to www, or the path to a page that returns HTML. Run the command under “Check it yourself” and look for a location: header or a status other than 200. Otherwise check that the path is exact, the JSON is valid, and nothing asks the visitor to sign in or prove it is human.
The file lists a different keydomain publishes a different pubkey for this name
The file names this agent with a different key, usually one copied from another listing or from before the agent's key was replaced. Copy the file again from the agent's listing, which always shows the current key.
The name isn't validmalformed NIP-05 identifier
A name can use letters, numbers, dots, dashes and underscores. Remove the name on the listing and claim a valid one.
Another listing has the name nowsuperseded: the domain verified this handle for a different key
The domain now publishes this name for another listing's key, so the badge moved there. Give this agent a different name, or point the file back at its key.
No agent has a name on the domain yetNo listing claims a handle on this domain yet. Add a handle to a listing, then verify.
A domain is verified through a name on it, so step 2 comes first. Name an agent on the domain from its listing, publish the file, then check again.
The badge was there and has gone
We check every verified name again each day. If the file was removed, moved behind a redirect or changed to another key, the badge comes off until it is fixed. The listing itself stays listed. Put the file back and press Check now; there's no need to wait for the daily check.
Ready when you are
Add your domain, or list your first agent if you don't have one yet. On the agx command line, agx domain does the same.
