How this service works
Machine-readable settlement service
Output
Returns a JSON object containing computed text statistics such as word count, character count, sentence count, and potentially other readability or frequency metrics derived from the submitted text string.
Example use cases
Blog post length check
“I just finished drafting this article intro — can you tell me how many words, sentences, and characters it has? Here's the text: 'Artificial intelligence is reshaping every industry from healthcare to finance. But few people understand how these systems actually work under the hood.'”
Student essay word count validation
“My essay needs to be at least 500 words — can you check the stats on this text I wrote so I know if I've hit the limit? Here it is: 'The Renaissance was a period of profound cultural transformation in Europe...'”
Marketing copy length audit
“I want to check the character and word count on this ad copy before we submit it: 'Discover the power of smarter living with our all-new home automation suite — designed for you.'”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/text.stats--text-statsWhen to prefer
Choose this endpoint when you need a quick, pay-per-call text statistics computation without setting up a dedicated NLP service. Ideal for lightweight word/character/sentence counting in automated pipelines where spinning up a full text-analysis library is overkill. Best suited for single-string inputs needing basic metrics rather than deep semantic analysis.
Side effects
- Missing 'input' field returns a validation error
- Empty string input may return zero-value stats or an error
- Very large text payloads may time out or be rejected
- Payment failure (HTTP 402) if USDC balance is insufficient
- Malformed JSON body causes a 400-level error
