Example use cases
Format international phone number
“I have a phone number for a contact in Germany but I don't know the country dialing prefix — can you look up Germany's international calling code so I can format the full number correctly?”
Travel dialing instructions
“I'm about to call someone in Brazil from the US — what's Brazil's international calling code so I know what to dial before their local number?”
Auto-populate country dial prefix
“My app needs to pre-fill the phone country code field for users in South Korea — what's the international dialing prefix for South Korea?”
Technical details
Endpoint
GEThttps://globalrules-api.onrender.com/api/v1/country/JP/calling_code?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single, verified calling code fact for a specific country without building your own country database. Ideal for agents that need to format international phone numbers, auto-populate dial prefix fields, or provide travel dialing instructions. At $0.01 per call it is cost-effective for on-demand lookups. Prefer this over a full country dataset download when you only need the calling code for one country at a time.
Side effects
- Invalid or unsupported country code returns an error or empty response
- Country code must be exactly 2 uppercase letters (ISO 3166-1 alpha-2); malformed codes will fail
- Service hosted on Render free tier may have cold-start latency or occasional downtime
- Only 106 countries are supported; obscure territories may not be available
- Payment failure via x402 protocol will block the request
