Technical details
Endpoint
POSThttps://kite-endpoints.vercel.app/api/chatgpt-4oWhen to prefer
Choose this endpoint when you need GPT-4o inference capability but want to pay per request using USDC cryptocurrency on Base chain instead of maintaining an OpenAI subscription or API key. Ideal for agents operating in crypto-native environments or when avoiding recurring subscription costs.
Side effects
- Payment failure: insufficient USDC balance on Base chain results in 402 error
- Invalid or missing prompt body returns an error response
- OpenAI upstream downtime causes 503 or timeout
- Rate limits from underlying OpenAI API may cause throttling
- Malformed JSON input may result in parse errors
