Technical details
Endpoint
GEThttps://api.certaindata.ai/ca054d66abad4d6ea80ba43013b61743-cd/country-data/:iso2When to prefer
Use this endpoint when you have a known ISO 3166-1 alpha-2 country code and need structured country metadata quickly. Prefer over the sibling search endpoint when the code is already known, to avoid ambiguity in name-based lookups. Ideal for enriching datasets that contain ISO-2 codes with human-readable names, capitals, and calling codes.
Side effects
- Invalid or unrecognized ISO-2 code returns an error or empty result
- Passing a 3-letter ISO code instead of 2-letter code may fail validation
- Lowercase iso2 codes may or may not be normalized — behavior uncertain
- Payment failure (x402) if USDC balance is insufficient
