How It Works

01

Authenticate

Generate an Ed25519 keypair. Request a challenge, sign it, get an API key. No email, no OAuth, no CAPTCHA.

02

Operate

Register domains, push events, manage DNS, send email — all through clean REST APIs with your API key.

03

Scale

Real-time event delivery via WebSocket. Multi-domain management. Automatic renewal. Built for production agents.

Start in Minutes

Generate your own Ed25519 keypair, sign a challenge, get an API key. No email, no OAuth.

0. Generate your keypair (once)

shell
# You need YOUR OWN Ed25519 keypair — this is your agent identity
ssh-keygen -t ed25519 -f agent_key -N ""
# → agent_key (private) + agent_key.pub (public)

# Then get a challenge with your public key:
curl -X POST https://auth.gentik.io/challenge \
  -H "Content-Type: application/json" \
  -d '{"publicKey": "'"$(cat agent_key.pub)"'"}'

# Returns: { challengeId, challenge, fingerprint }

2. Sign & verify

curl
curl -X POST https://auth.gentik.io/verify \
  -H "Content-Type: application/json" \
  -d '{
    "challengeId": "challenge_...",
    "signature": "-----BEGIN SSH SIGNATURE-----..."
  }'

# Returns: { status, agentId, apiKey }

3. Use your API key

curl
# Check domain availability
curl https://agentdomains.dev/api/domains/check?domain=myagent.dev \
  -H "Authorization: Bearer gtk_..."

# Register a domain
curl -X POST https://agentdomains.dev/api/domains/register \
  -H "Authorization: Bearer gtk_..." \
  -H "Content-Type: application/json" \
  -d '{"domain": "myagent.dev", "years": 1, "registrant": {...}}'

Built For

Native Auth

Ed25519 challenge-response. Works with SSH keys, raw hex, or base58 (Solana wallets). No browser, no email, no CAPTCHA.

Clean REST APIs

JSON in, JSON out. Comprehensive error messages with hints. Idempotency keys. Rate limit headers on every response.

Machine-Readable Docs

llms.txt, OpenAPI spec, and agents.json. Everything an LLM needs to discover and use the platform autonomously.
