> Country and Currency Codes – Name Normalise is a paid API for AI agents from country-codes-iso.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).

Normalises free-text country name variants (e.g. USA, U.S., United States of America) to ISO 3166-1 alpha-2 and alpha-3 codes, with a confidence score, up to 25 names per call.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability country-and-currency-codes-name-normalise-1f2b3542
```

Example prompt: Can you normalise these country name variants to their ISO 3166-1 alpha-2 and alpha-3 codes with confidence scores: USA|U.S.|Deutschland|United States of America|UK?

## When to prefer this

Choose this endpoint when you need to resolve informal, user-typed, or multilingual country name variants to authoritative ISO 3166-1 codes at scale (up to 25 per call) and require a per-result confidence score to flag uncertain matches. It is purpose-built for name normalisation with fuzzy matching, unlike a plain code-conversion endpoint which only handles already-structured codes.

## Known failure modes

- More than 25 names submitted in a single call — excess names may be skipped or rejected
- Completely unrecognisable or misspelled strings return low confidence or null codes
- Ambiguous names that map to multiple countries (e.g. 'Georgia') return the best-guess match with lower confidence
- Missing 'names' query parameter causes a 400-level error
- Service degraded flag set to true when operating in reduced-accuracy mode

## How this service works

Normalise country names like USA, U.S. or United States of America to ISO codes; up to 25 per call, with confidence.

## Output

Returns an array of result objects, one per input name, each containing the original input string, the matched canonical country name, ISO alpha-2 code, ISO alpha-3 code, match status, the field matched on, and a numeric confidence score. Also includes a summary, verdict, and optional degraded/disclaimer fields at the response level.
