Hostinger Domain API 2026: Automate Domain Registration & Management

Hostinger's public API gives developers programmatic access to key platform features including domain registration, DNS record management, domain renewal, and availability checking. The API uses standard REST conventions with JSON request/response bodies and HTTP status codes.

This is particularly valuable for digital agencies managing dozens of client domains, SaaS platforms that register domains on behalf of users, or developers building tools that need domain data. Instead of clicking through hPanel for every operation, API users can script and automate repetitive tasks.

Step 1: Get API credentials. Log into hPanel → Account → API Tokens. Generate a new API token with the appropriate permissions (domain:read, domain:write, dns:read, dns:write).

Step 2: Read the API documentation. Hostinger maintains developer docs at developers.hostinger.com with full endpoint reference, authentication instructions, and code examples in cURL, Python, and PHP.

Step 3: Make your first request. Test connectivity with a simple domain availability check:

curl -X GET 'https://api.hostinger.com/v1/domains/availability?domain=example.com' 
  -H 'Authorization: Bearer YOUR_API_TOKEN' 
  -H 'Content-Type: application/json'

Domain Availability: GET /v1/domains/availability?domain={domain} — Check if a domain is available for registration.

Domain Registration: POST /v1/domains — Register a new domain. Payload includes domain name, TLD, registration period, contact details, and WHOIS privacy preference.

Domain Renewal: POST /v1/domains/{domain}/renew — Renew a domain for a specified period.

List Domains: GET /v1/domains — Retrieve all domains in the account with status and expiration dates.

DNS Records: GET/POST/PUT/DELETE /v1/domains/{domain}/dns — Full CRUD operations on DNS records. Create, update, or delete A, CNAME, MX, TXT, and SRV records programmatically.

WHOIS Lookup: GET /v1/domains/{domain}/whois — Retrieve WHOIS data for any domain.

Digital agencies: Automate domain registration for new client onboarding. Register a domain, configure DNS, and set up email — all via API in a single script that runs when a client signs up.

SaaS platforms: Register custom domains for users automatically when they upgrade to a paid tier. DNS configuration happens instantly via API without manual intervention.

Resellers: Build a white-label domain registration service on top of Hostinger's infrastructure. Set custom pricing, use your brand, and Hostinger handles the backend fulfillment.

Monitoring tools: Query domain expiration dates, WHOIS data, and DNS records automatically to alert you before domains expire or configurations drift.

Hostinger's API enforces rate limits to prevent abuse. Typical limits are around 60-120 requests per minute depending on the endpoint — consult the developer documentation for current limits as they may change.

Best practices for API usage: implement exponential backoff for rate limit errors (HTTP 429), cache domain availability results for 60 seconds before re-querying, batch DNS record operations where possible, and use webhook notifications where available rather than polling for status updates.
