How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
Returns the classified category label for the input text, likely alongside a confidence score or ranked list of matching categories. If custom categories are provided, classification is performed against those; otherwise the default set (tech, finance, health, sports, politics, entertainment, science, business) is used.
Example use cases
News article topic detection
“I have this news article excerpt and I want to know if it falls under politics, science, or business: 'NASA announced a new lunar mission funded by a public-private partnership with SpaceX and Blue Origin.' Can you classify it for me?”
Customer support ticket routing
“Classify this support ticket so I can route it to the right team — categories should be billing, technical, account, and general: 'I was charged twice for my subscription this month and I need a refund immediately.'”
Content moderation topic tagging
“Tag this social media post with the most relevant topic from: sports, entertainment, politics, health, science — here's the text: 'LeBron James announced he will participate in the 2024 Paris Olympics representing Team USA.'”

Endpoint
GEThttps://klymax402.com/api/text-classifier/api/classifyWhen to prefer
Use this endpoint when you need lightweight, fast text classification against a fixed or custom set of topic categories and do not want to manage API keys. Ideal for content routing, tagging pipelines, or topic detection tasks within an agent workflow that already uses x402 micropayments on Base.
Side effects
- Text input shorter than 50 characters may produce inaccurate or refused results
- Invalid or empty categories array may cause fallback to defaults or error
- Payment failure (insufficient USDC balance) returns HTTP 402
- Ambiguous text spanning multiple categories may produce low-confidence or split results
- Network timeout or service unavailability returns HTTP 5xx
