What you should know about .io
.io is formally the country-code TLD of the British Indian Ocean Territory, but is read worldwide as short for “input/output”. It is one of the most popular extensions for tech startups, developer tools and SaaS products.
Registry: Identity Digital
- Open to everyone, with no requirements regarding residence or purpose.
- Search engines treat it like a generic TLD, so it does not imply a country targeting.
Register .io domains via API
You check availability and price with a GET request; registration is a POST with the domain, term and owner contact handle. The cost is debited directly from your prepaid wallet, and the domain.registered webhook reports completion.
# Check availability and price
curl -H "Authorization: Bearer $DRAPI_KEY" \
https://domain-reseller-api.de/api/v1/domains/check/example.io
# Register
curl -X POST -H "Authorization: Bearer $DRAPI_KEY" \
-H "Content-Type: application/json" \
-d '{
"domain": "example.io",
"years": 1,
"contacts": {
"owner": "HANDLE-123"
}
}' \
