How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns a JSON object with computed text statistics such as word count, character count, sentence count, paragraph count, average word length, average sentence length, and readability metrics (e.g. Flesch-Kincaid score) derived from the submitted text.
Example use cases
Readability check before publishing
“Before I publish this blog post draft, can you run it through text stats so I know the word count, sentence count, and how readable it is? Here's the text: 'Artificial intelligence is transforming industries at an unprecedented pace, enabling automation and smarter decision-making across sectors.'”
Content length validation for SEO
“I need to check the stats on this article body — specifically word count and character count — to make sure it meets SEO minimums. Here's the content: 'Search engine optimization requires consistent effort and quality content creation to achieve meaningful organic traffic growth over time.'”
Automated writing quality audit
“For my agent pipeline, can you compute text statistics — including sentence count and readability scores — for this user-submitted review text: 'The product exceeded my expectations in every way. Delivery was fast and packaging was excellent. I would highly recommend this to anyone.'?”
Technical details
Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/text/stats?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, deterministic text metrics (word count, character count, sentence count, readability) for a single text payload up to 250,000 characters, especially within machine-payable x402 micro-payment workflows where per-call pricing at $0.001 USDC is acceptable. Prefer this over heavyweight NLP APIs when you only need statistical measures rather than semantic understanding or entity extraction.
Side effects
- Text exceeds 250,000 character limit — request rejected with validation error
- Empty or missing 'text' field in body — returns schema validation error
- Payment not included or insufficient — x402 payment required error returned
- Malformed JSON body — returns parse error
- Network timeout on Railway deployment — transient 5xx error
