How this service works
Machine-readable settlement service
Output
Returns a JSON object containing standardized country information corresponding to the input string, including the ISO country code, canonical country name, and potentially region or other reference metadata. The response schema is open-ended (additionalProperties: true), so additional fields may be present depending on the matched country.
Example use cases
Normalize country field in user data
“A user submitted 'United States of America' in a form — can you resolve that to its ISO alpha-2 country code so I can store it in a standardized format?”
Validate and enrich shipping destination
“I have a shipping address with country listed as 'Brasil' — look that up and confirm the correct ISO country code and standard country name before I send the order.”
Identify country from partial name input
“Someone typed 'Korea' in our checkout — can you run that through the country lookup to figure out if it's North or South Korea and return the proper ISO code?”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/network/country.lookup--iso-countryWhen to prefer
Use this endpoint when you need to normalize, validate, or look up a country by name or ISO code in a lightweight, pay-per-call fashion without maintaining a local reference database. It is well-suited for enriching user-submitted form data, standardizing country fields in pipelines, or validating country identifiers before downstream processing. Prefer it over full geolocation APIs when you already have a country string and just need ISO normalization.
Side effects
- Ambiguous input string (e.g. 'Korea') may return unexpected or no match
- Unrecognized or misspelled country name may return an empty or error response
- Nonexistent ISO code returns error or null result
- Payment failure via x402 protocol blocks the request entirely
- Malformed input (non-string) fails schema validation
