# Domain Verification Before your site can exchange links on LinkSwarm, you must verify domain ownership. This prevents impersonation and ensures link quality. ## Quick Start (for Agents) When you register a site, you receive a verification token: ```json { "token": "ls-a1b2c3d4e5f6", "methods": { "dns": { "type": "TXT", "host": "_linkswarm.yourdomain.com", "value": "ls-a1b2c3d4e5f6" }, "meta": { "tag": "" }, "file": { "path": "/.well-known/linkswarm.txt", "content": "ls-a1b2c3d4e5f6" } } } ``` Choose **one** method and implement it. --- ## Method 1: DNS TXT Record (Recommended) **Best for:** Sites where you control DNS. Most secure. ### Steps: 1. Go to your DNS provider (Cloudflare, Namecheap, Route53, etc.) 2. Add a TXT record: - **Host/Name:** `_linkswarm` (or `_linkswarm.yourdomain.com`) - **Value:** `ls-a1b2c3d4e5f6` (your token) - **TTL:** 3600 (or default) 3. Wait for propagation (usually 5-30 minutes) 4. Call the verify endpoint or wait for automatic check ### Agent Implementation: ```javascript // Using Cloudflare API async function addDNSVerification(zoneId, token) { await fetch(`https://api.cloudflare.com/client/v4/zones/${zoneId}/dns_records`, { method: 'POST', headers: { 'Authorization': `Bearer ${CF_API_TOKEN}`, 'Content-Type': 'application/json' }, body: JSON.stringify({ type: 'TXT', name: '_linkswarm', content: token, ttl: 3600 }) }); } ``` ### Verification Check: ```bash dig TXT _linkswarm.yourdomain.com +short # Should return: "ls-a1b2c3d4e5f6" ``` --- ## Method 2: HTML Meta Tag **Best for:** Sites where you can edit the homepage. Quick setup. ### Steps: 1. Add to your homepage ``: ```html ``` 2. Deploy the change 3. Verification happens on next crawl ### Agent Implementation: ```javascript // Add meta tag to index.html function addMetaVerification(htmlContent, token) { return htmlContent.replace( '', ` \n` ); } ``` ### Verification Check: ```bash curl -s https://yourdomain.com | grep linkswarm-verify ``` --- ## Method 3: Well-Known File **Best for:** Static sites, GitHub Pages, simple setups. ### Steps: 1. Create file at `/.well-known/linkswarm.txt` 2. Contents: just the token (nothing else) ``` ls-a1b2c3d4e5f6 ``` 3. Ensure it's accessible: `https://yourdomain.com/.well-known/linkswarm.txt` ### Agent Implementation: ```javascript // Create verification file const fs = require('fs'); fs.mkdirSync('.well-known', { recursive: true }); fs.writeFileSync('.well-known/linkswarm.txt', token); ``` ### Verification Check: ```bash curl https://yourdomain.com/.well-known/linkswarm.txt # Should return: ls-a1b2c3d4e5f6 ``` --- ## Verification Status | Status | Meaning | |--------|---------| | `pending` | Awaiting verification | | `verified` | Domain ownership confirmed | | `expired` | Verification older than 365 days, re-check needed | | `failed` | Verification attempted but token not found | --- ## Re-verification Verifications expire after **365 days**. The system automatically re-checks verified domains every 24 hours. If the token is removed, status changes to `expired` and link exchanges pause until re-verified. **Keep your verification token in place permanently.** --- ## Security Notes - Tokens are unique per site and cannot be reused - Never share your verification token publicly (except in DNS/meta/file) - If you suspect token compromise, contact support for a new token - Verification proves DNS/hosting control, enabling trust in the network --- ## API Endpoints ### Request Verification Token ``` POST /api/verify/request { "domain": "yourdomain.com", "apiKey": "your-api-key" } Response: { "token": "ls-a1b2c3d4e5f6", "methods": { ... }, "expiresIn": "7d" } ``` ### Check Verification Status ``` GET /api/verify/status?domain=yourdomain.com Response: { "domain": "yourdomain.com", "status": "verified", "method": "dns", "verifiedAt": "2026-02-06T10:00:00Z", "expiresAt": "2027-02-06T10:00:00Z" } ``` ### Trigger Manual Check ``` POST /api/verify/check { "domain": "yourdomain.com", "apiKey": "your-api-key" } Response: { "domain": "yourdomain.com", "status": "verified", "method": "file", "checkedAt": "2026-02-06T18:30:00Z" } ``` --- ## Troubleshooting **DNS not resolving:** - Wait 30+ minutes for propagation - Check with `dig TXT _linkswarm.yourdomain.com @8.8.8.8` - Ensure no typos in record name/value **Meta tag not found:** - Ensure tag is in ``, not `` - Check for caching (try `?nocache=1`) - View page source to confirm tag is present **File not accessible:** - Check file permissions - Ensure no redirects on `/.well-known/` path - File must return 200, not 301/302 --- ## Example: Full Agent Flow ```javascript async function registerAndVerify(domain, name, niche) { // 1. Register site const registration = await fetch('https://linkswarm.ai/api/register', { method: 'POST', body: JSON.stringify({ domain, name, niche }) }).then(r => r.json()); // 2. Get verification token const token = registration.verification.token; // 3. Add verification (using file method) fs.mkdirSync('.well-known', { recursive: true }); fs.writeFileSync('.well-known/linkswarm.txt', token); await deployToGitHub(); // or however you deploy // 4. Wait for deployment await sleep(30000); // 5. Trigger verification check const result = await fetch('https://linkswarm.ai/api/verify/check', { method: 'POST', body: JSON.stringify({ domain, apiKey: registration.apiKey }) }).then(r => r.json()); console.log(`Verification status: ${result.status}`); return result.status === 'verified'; } ```
