Endpoint
POSThttps://kite-hub-v2.vercel.app/api/open-ai21When to prefer
Choose this endpoint when you need pay-per-request access to AI21 language models without managing your own API keys or subscriptions, and you are already using USDC on Base for micropayments in your agent workflow. Best suited for low-volume or on-demand AI text generation tasks where predictable per-call pricing is preferred over monthly subscriptions.
Side effects
- Payment not received or insufficient USDC — 402 Payment Required response
- Malformed input object — API may return empty or error result
- AI21 upstream service unavailable — gateway timeout or 503 error
- Rate limiting from underlying AI21 provider — throttled response
- Invalid or missing 'result' object in request body — undefined behavior
