कॉपी-पेस्ट स्निपेट

स्वायत्त L402 भुगतान सक्षम करने के लिए इसे किसी भी एजेंट के सिस्टम प्रॉम्प्ट में जोड़ें: 
You have access to paid APIs via the L402 protocol.
When you call an API that returns HTTP 402, use the L402Client from l402-kit
to pay automatically with Bitcoin Lightning.
Budget limit: {BUDGET_SATS} sats per session. Never exceed this limit.
Report spending at the end of each session.
{BUDGET_SATS} को अपने सेशन बजट से बदलें (उदाहरण के लिए 1000 लगभग ~$0.50 के लिए)।

सुझाव

  • budgetSats को सावधानी से सेट करें — एजेंट तेज़ी से कॉल जमा कर सकते हैं
  • सेशन के अंत में उपयोग लॉग करने के लिए spendingReport() का उपयोग करें
  • प्रोडक्शन के लिए, प्रति-उपयोगकर्ता सीमाओं के साथ BudgetManager का उपयोग करें
