How this service works
Small text utilities for agents and developers, paid per call: turn any text into a URL-safe slug, or extract the most frequent keywords (English and French stopwords removed). Up to 20,000 characters per call, deterministic, no data kept.
Output
A JSON object containing the computed result: for slugify requests, a 'slug' field with the URL-safe lowercase hyphenated version of the input text; for keyword extraction, a list of the most frequent meaningful words after stopword removal in English and French.
Example use cases
CMS URL slug generation
“I'm publishing a new blog post called 'How to Build Scalable REST APIs with Node.js' — can you convert that title into a clean URL-safe slug I can use as the post's permalink?”
Keyword extraction for SEO tagging
“Here's a 500-word product description for my e-commerce site. Can you pull out the most frequent meaningful keywords from it so I can use them as SEO tags? Remove common English filler words.”
Multilingual keyword analysis
“I have this French press release text — can you extract the top keywords from it, ignoring common French stopwords, so I can see what the main topics are?”
Technical details
Endpoint
POSThttps://api.genexxis.com/slugify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, stateless text utility that is guaranteed not to retain data — ideal for privacy-sensitive content. It is well-suited for automated pipelines that generate URL slugs or extract keywords at scale, billed per call with no subscription overhead. Prefer it over general-purpose LLMs for slug/keyword tasks where reproducibility and low cost per call matter more than semantic sophistication.
Side effects
- Text exceeds 20,000 character limit — request rejected with an error
- Empty or whitespace-only input — may return an empty slug or empty keyword list
- Non-text binary data submitted — unexpected output or error
- Payment not provided or invalid x402 payment — 402 Payment Required response
- Network timeout on very large inputs near the character limit
