How this service works
Call when an agent needs text normalized with nfkd. No network and no LLM. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/norm-nfkd first.
Output
Returns the input text after applying Unicode NFKD (Compatibility Decomposition) normalization, which decomposes characters into their base components and compatibility equivalents without any network calls or LLM involvement.
Example use cases
Normalize search index input
“I need to normalize this product description to NFKD before indexing it: 'Ａpple ＭacBook Ｐro ½ price financing available' — can you do that?”
Standardize user-submitted form text
“A user submitted their name as 'Ａndré Ｍüller' with fullwidth characters — can you run NFKD normalization on it so we can store it in a consistent unicode form?”
Prepare text for unicode-safe comparison
“Before I compare these two strings for equality, can you NFKD-normalize this one: 'café financé ½ litre'?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/norm-nfkd?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, fast, server-side NFKD unicode normalization without any LLM overhead or network lookups. Prefer the free sandbox POST /v1/sandbox/norm-nfkd first if available; use this paid endpoint when the sandbox is unavailable or rate-limited. Ideal for preprocessing pipelines that require consistent unicode normalization at scale.
Side effects
- Empty or missing text field returns validation error
- Text exceeding 100,000 characters is rejected
- Payment of exactly $0.001 USDC not provided results in 402 Payment Required
- Malformed JSON body returns 400 Bad Request
