How this service works
One specific fact for one country: VAT/GST rate, public holidays by country, visa requirements for travelers, tipping customs, power plug type, minimum wage, corporate tax, digital nomad visa, customs duty-free allowance and more. 138 countries, 55 fields, verified sources. Example: /api/v1/country/JP/vat
Output
A JSON object containing the country code (e.g. 'IN'), the week start day (e.g. 'Sunday' or 'Monday'), and an 'updated' timestamp indicating when the data was last verified.
Example use cases
Calendar app localization for India
“I'm building a calendar app and need to know what day the week starts in India — can you look up the week start convention for IN so I display the correct first column?”
Scheduling tool international support
“My scheduling tool needs to show the right week layout for users in India. What's the first day of the week there — Sunday, Monday, or something else?”
Cross-country calendar comparison
“I'm comparing how weeks are laid out across different countries. What day does the week officially start in India?”
Technical details
Endpoint
GEThttps://globalrules-api.onrender.com/api/v1/country/IN/week_startWhen to prefer
Choose this endpoint when you need a single, verified, structured fact about the week start convention for a specific country, especially for calendar localization, scheduling tools, or international apps. It is more reliable than scraping Wikipedia or inferring from locale strings, and cheaper than calling a general-purpose LLM for country facts.
Side effects
- Invalid or unsupported country code returns an error or empty result
- Country code not among the 106 supported countries returns a not-found response
- Network timeout from the hosted Render.com service during cold start
- Payment failure (x402) if USDC balance is insufficient
