How this service works
Normalize Japanese (JP) text to a canonical form: fullwidth↔halfwidth conversion, halfwidth-katakana folding, invisible-character removal, and whitespace cleanup — each transformation toggleable. Returns a per-change log. Use to deduplicate or match text where '東京' and 'ﾄｳｷｮｳ' must compare equal.
Output
Returns the normalized Japanese text string along with a per-change log detailing each transformation applied (e.g. which characters were converted, removed, or adjusted), enabling the caller to audit exactly what changed.
Example use cases
Example prompt
“Normalize this Japanese text so that fullwidth and halfwidth characters are unified and any invisible characters are removed: '東京 ＡＢＣ ﾄｳｷｮｳ test' — turn on all normalization options.”
Technical details
Endpoint
POSThttps://furigana.agentic-jp.com/normalizeWhen to prefer
Use this endpoint when you need to canonicalize Japanese text for deduplication, matching, or storage — especially when input may contain mixed fullwidth/halfwidth forms, halfwidth katakana (e.g. from legacy systems or mobile input), zero-width or invisible Unicode characters, or inconsistent whitespace. Prefer this over generic Unicode normalization libraries when you need a per-change audit log and toggleable transformations specific to Japanese character encoding conventions.
Side effects
- Input text exceeds 5000 character limit — API returns validation error
- Non-Japanese or non-Unicode text passed — may return unchanged or partial normalization
- Invalid options object structure — API may ignore or error on unknown toggle keys
- Network timeout for large payloads near the character limit
- Payment failure via x402 protocol — call not executed
