“Is this message spam or legitimate? Classify it: 'Congratulations! You have been selected to receive a $500 gift card. Click here to claim your prize now.'”
Sentiment or topic tagging for reviews

Choose this endpoint when you need lightweight, pay-per-call AI text classification without a subscription or API key — ideal for agents that handle sporadic or low-volume classification tasks and want to pay only per inference via x402 USDC micropayments on Base mainnet. Best suited for short-to-medium text inputs requiring a single classification or label.
