How this service works
Calendar and Japan data APIs for AI agents: worldwide holidays and business days (200+ countries), plus Japanese text-to-structure (address, name, bank, company normalization). Pay per call in USDC via x402, no API key.
Output
A JSON object containing: parsed prefecture (pref), city, town, and street/block number (addr), a formatted canonical address string, the original input, normalization level achieved, any unparsed remainder (other), and a point object with latitude, longitude, and the confidence level of the geocoordinate.
Example use cases
E-commerce shipping address cleanup
“I have a customer-submitted Japanese address '大阪府大阪市北区梅田１丁目３−１−２００' that might be messily formatted — can you normalize it into clean structured fields (prefecture, city, town, street) with coordinates so I can store it properly in our shipping database? Use full normalization depth.”
Real estate geocoding pipeline
“I need to geocode this Japanese address for a property listing: '神奈川県横浜市中区山下町１'. Can you break it down into structured components and give me the latitude and longitude? Use level 8 normalization.”
Address-level data deduplication
“We have two address strings that might refer to the same location: '東京都新宿区西新宿2-8-1' and '東京都新宿区西新宿２丁目８番１号'. Can you normalize both to their structured canonical forms using full normalization so I can compare them?”
Technical details
Endpoint
POSThttps://x402-ja-api.onrender.com/v1/address/normalizeWhen to prefer
Use this endpoint when you need to parse, normalize, or geocode Japanese-language address strings into structured machine-readable components. It is specifically designed for Japanese address notation (kanji, kana, numeric mixed formats) and returns both structured fields and geocoordinates in a single call. Prefer this over generic geocoding APIs when the input is in Japanese and you need prefecture/city/town decomposition alongside coordinates.
Side effects
- Address too ambiguous or incomplete — returns lower normalization level than requested
- Non-Japanese or romanized address input yields poor parse quality
- Very rural or recently renamed addresses may not resolve fully
- Service unavailable on Render free tier due to cold start or sleep (timeout)
- Insufficient USDC balance or x402 payment failure returns 402 error
