How this service works
Call when an agent needs counts of word 1-grams. No network and no LLM. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/ngram-word-1 first.
Output
Returns a map or dictionary of each unique word found in the input text to its integer occurrence count (1-gram frequency table), computed locally without any network requests or LLM involvement.
Example use cases
Word frequency analysis for SEO
“Here's the body copy from our landing page — can you count the frequency of every word so I can see which terms we're overusing or underusing?”
NLP preprocessing for keyword extraction
“I need a word frequency count for this customer review dataset entry: 'The product was great but the delivery was slow and the packaging was damaged' — give me the unigram counts so I can feed them into my classifier.”
Vocabulary profiling for readability audit
“Take this paragraph from our documentation and count how many times each individual word appears — I want to see if we're repeating certain terms too heavily.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/ngram-word-1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need exact, deterministic word-level unigram frequency counts from a text without relying on an LLM or external network call. It is ideal for NLP preprocessing pipelines, SEO keyword audits, readability analysis, or any workflow that needs a reproducible word frequency table at low cost. Prefer the free sandbox POST /v1/sandbox/ngram-word-1 first for testing; use this paid endpoint when sandbox access is unavailable or rate-limited.
