Technical details
Endpoint
POSThttps://x402.agentutility.ai/classifyWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call text classification API with no subscription, settled in USDC on Base via x402. Ideal for AI agents that need to programmatically classify content (e.g. spam detection) without managing API keys or monthly plans, especially in autonomous agent workflows that already use x402 micropayments.

- Missing or empty input text returns an error
- Payment failure or insufficient USDC balance blocks the request
- Ambiguous or very short text may produce low-confidence or unexpected labels
