NIP-05 Automated PR Service

Automates NIP-05 identifier registration via pull requests. Users submit their Nostr pubkey through a web form, and the system automatically creates a PR to add them to the nostr.json file.

For Users

Visit the registration form to request your NIP-05 identifier. Once your PR is approved and merged, your identifier will be active.

1. User submits username + pubkey via the web form
2. Express server validates input and triggers a GitHub repository_dispatch event
3. GitHub Actions workflow updates nostr.json and creates a PR using peter-evans/create-pull-request
4. Repository owner reviews and merges the PR

Setup Instructions

0. Fork this repo

Clone the repository in your github by forking this repository. If you have already forked this repo, you can skip this step.

1. Create a GitHub Personal Access Token

1. Go to GitHub Settings > Developer settings > Personal access tokens > Fine-grained tokens
2. Create a new token with:
   • Repository access: Only select this repository
   • Permissions:
     • Actions: Read and write (required to trigger repository_dispatch)
     • Contents: Read and write
     • Metadata: Read-only (auto-granted)
     • Pull requests: Read and write
3. Copy the token (starts with github_pat_)

2. Enable GitHub Actions Workflow Permissions

1. Go to your repository's Settings → Actions → General
2. Scroll to "Workflow permissions"
3. Select "Read and write permissions"
4. Check "Allow GitHub Actions to create and approve pull requests"
5. Click Save

3. Deploy to Zeabur

1. Go to Zeabur Dashboard
2. Create a new project or select an existing one
3. Click Add Service and select Git
4. Connect your GitHub repository (bitkarrot/nip05-service)
5. Zeabur will automatically detect the Dockerfile and deploy

4. Set Environment Variables in Zeabur

In your Zeabur service settings, add these environment variables:

• GITHUB_TOKEN: Your GitHub personal access token (required)
• GITHUB_OWNER: Your GitHub username (default: bitkarrot)
• GITHUB_REPO: Your repository name (default: nip05-service)
• ALLOWED_ORIGIN: CORS origin (default: *)

5. Configure Your Domain (Optional)

In Zeabur service settings, add a custom domain under Domains section. The service will be accessible at the provided URL.

6. Configure Repository (For Forks)

If you fork this repository, update the environment variables in Zeabur:

• GITHUB_OWNER: Your GitHub username
• GITHUB_REPO: Your repository name

Files

• .well-known/nostr.json - The NIP-05 identifier mapping
• add-nip05.html - User-facing registration form
• api/submit-nip05.js - API handler for form submissions
• server.js - Express server entry point
• Dockerfile - Container configuration for Zeabur
• .github/workflows/add-nip05.yml - GitHub Actions workflow

Security Notes

• The GitHub token is stored as a Zeabur environment variable, never exposed to users
• Input validation happens both client-side and server-side
• The workflow validates username and pubkey format before making changes
• PRs require manual approval before merging

NIP-05 Format

Once registered, users can set their NIP-05 identifier in their Nostr profile as:

username@yourdomain.com

For the root identifier _, it displays as just the domain.
