How this service works
Machine-readable settlement service
Output
Returns a JSON object containing an 'operation' string describing what was performed and a 'result' field with the country data associated with the provided code. The response may include additional fields with country metadata such as name, region, or other structured details.
Example use cases
Enrich e-commerce shipping data
“I have a country code 'FR' coming in from our checkout form — can you resolve it to full country details so I can validate and display the shipping destination properly?”
Validate user-submitted country codes
“A user just entered 'GBR' as their country — can you look that up and confirm it's a valid country code and tell me what country it maps to?”
Decode analytics country field
“Our analytics pipeline is giving me two-letter country codes like 'JP' and I need to resolve them to full country info — can you look up 'JP' for me?”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/f/country.lookupWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call country code resolution with no subscription or API key setup, and you only need occasional lookups. Ideal for agents that need to enrich or validate ISO 2-letter or 3-letter country codes inline during a workflow without integrating a full geolocation or reference data service.
Side effects
- Invalid or unrecognized country code returns an error or empty result
- Missing 'input' field in request body causes a 400-level validation error
- Ambiguous code (e.g. a code that doesn't match any ISO standard) may return no result
- Network or service unavailability returns a 5xx error
- Malformed input (non-string or overly long value) may be rejected
