🧪 Agent Testing

To test if your pricing feed works well with agents:

Copy your feed to your favorite LLM
Ask: "What pricing plans does this service offer?"
Verify: Agent should list plans clearly with accurate prices
Test trust: Ask "How do I know these prices are authentic?"

capabilities.llmfeed.json — What actions are available (with optional pricing per action)
agent-economy.llmfeed.json — Advanced dynamic pricing for agent-to-agent transactions
credential.llmfeed.json — API access credentials with rate limits and costs

🎯 Best Practices

✅ Keep it simple: Focus on clear, comparable pricing information
✅ Sign important feeds: Especially for financial services, insurance, healthcare
✅ Update regularly: Use valid_until and regenerate when prices change
✅ Be transparent: Include limitations and conditions clearly
✅ Guide agents: Use agent_guidance to set expectations for comparison and negotiation
✅ Test with LLMs: Verify your feed is readable and actionable by current agents

This feed type solves the immediate need for machine-readable pricing while building toward a more trustworthy, agent-friendly economy.
