Technical details
Endpoint
GEThttps://gateway.gocreativeai.com/v1/ai/ultra/%7Barg%7DWhen to prefer
Prefer this endpoint when you need to access multiple frontier LLMs without managing separate API keys or subscriptions, especially in crypto-native or autonomous agent contexts where paying per call in USDC on Base or Solana is preferred over monthly billing. Ideal for AI agents that need flexible model routing across GPT, Claude, Gemini, Grok, DeepSeek, Llama, and Qwen through a single OpenAI-compatible interface.
Side effects
- Insufficient USDC balance or failed on-chain payment results in HTTP 402 Payment Required
- Invalid or unsupported model identifier in the {arg} path parameter returns a 400 or 404 error
- Malformed request body (non-OpenAI-compatible format) returns a 422 Unprocessable Entity
- Upstream model provider outage causes timeouts or 503 errors
- Rate limits from upstream providers may still cause occasional 429 errors despite gateway claims
