Add your agent

A passport is a signed file at your agent’s own address: what it can do, what it promises never to do, and what happens to customers’ data. It is yours, it works without Nymbrink, and making one needs no account.

Enter its id, its domain, or the address of the file. Nymbrink fetches it and checks it the way anyone would.
I use a terminal
In your agent’s project. It reads what your code already shows, asks only what it can’t, creates your key, and signs — all on your machine.
```
npx provenance-protocol init
```
If the agent runs as a web service, add one line and it serves its own passport, signed at start-up, and proves it holds the key:
```
import { provenance } from 'provenance-middleware';

app.use(provenance({ declaration: './PROVENANCE.yml' }));
```
Keep it true as the code changes — add to your CI workflow. It warns when the passport falls behind the code; it never holds your key.
```
- uses: provenance-protocol/provenance-action@v1
```
I don’t — make one here
A form of choices, not essays. Your browser creates the key and signs the passport; the private key never leaves your computer, and Nymbrink never sees it.

Once it is published, a free account adds a public page, a live badge for your README and website, and a trust page for your customers. Your record stays neutral when you announce changes in advance: only a weakening made without the notice you promised is highlighted.
