Technical details
Endpoint
POSThttps://x402-ai-peach.vercel.app/api/alt-textWhen to prefer
Choose this endpoint when you need AI-generated alt text paid on a per-call basis via x402 micropayments without a subscription. Ideal for agents that process images infrequently or need to pay programmatically with USDC stablecoins. Prefer over subscription-based vision APIs when cost control per-image is critical or when building crypto-native workflows.
Side effects

- Invalid temperature value (outside 0.0–2.0 range) may cause error or unexpected output
- Oversized image or message payload may exceed token limits
- Network timeout on streaming responses if stream:true is set
