Endpoint
POSThttps://x402-nvidia.vercel.app/api/llama-guard-4When to prefer
Use this endpoint when you need a dedicated, NVIDIA-backed Llama Guard 4 safety classifier accessible via x402 micropayments without managing API keys or NVIDIA accounts. Ideal for agents that need on-demand, pay-per-call content moderation without subscription overhead, especially when already operating in an x402 payment ecosystem.
Side effects
- Missing or malformed choices/messages array returns 400 or empty response
- Payment not processed or x402 header missing results in 402 Payment Required
- NVIDIA NIM backend timeout causes delayed or 503 response
- Content too long exceeds model context window, returning an error
- Ambiguous borderline content may receive inconsistent safety labels across calls
