AgentBudget – Real-time dollar budgets for AI agents
Hey HN, I built AgentBudget after an AI agent loop cost me $187 in 10 minutes — GPT-4o retrying a failed analysis over and over. Existing tools (LangSmith, Langfuse) track costs after execution but don't prevent overspend. AgentBudget is a Python SDK that gives each agent session a hard dollar budget with real-time enforcement. Integration is two lines: import agentbudget agentbudget.init("$5.00") It monkey-patches the OpenAI and Anthropic SDKs (same pattern as Sentry/Datadog), so existing code works without changes. When the budget is hit, it raises BudgetExhausted before the next API…

What it does
AgentBudget is the ulimit for AI agents. Just like Unix systems have ulimit to prevent a single process from consuming all system resources, AgentBudget prevents a single agent session from consuming your entire AI budget. - AgentBudget/agentbudget

AgentGuard – Auto-kill AI agents before they burn through your budget2025 · github.com · ▲47Your AI agent hits an infinite loop and racks up $2000 in API charges overnight. This happens weekly to AI developers. AgentGuard monitors API calls in real-time and automatically kills your process when it hits your budget limit. How it works: Add 2 lines to any AI project: const agentGuard = require('agent-guard'); await agentGuard.init({ limit: 50 }); // $50 budget // Your existing code runs unchanged const response = await openai.chat.completions.create({...}); // AgentGuard tracks costs automatically When your code hits $50 in API costs, AgentGuard stops…

Hey HN, I noticed there are 1,000+ MCP skills on GitHub with zero way for creators to charge for them. So I built Agent37. Selling Claude skills today means asking customers to download your skill, set up Claude Code on their laptops, configure MCP servers, and pray it works. No trial, no updates, often you're just handing over the source. Agent37 lets creators upload a skill, share a link, and anyone can try it instantly (no Claude account needed). Built-in Stripe, creators keep 80%. Looking for feedback on the approach. Would you use something like this?
- PCPaylooop – Cost visibility for AI agents2025 · ▲12
Hi HN, I’m Yahya, founder of Rocket Money (formerly Truebill, YC W16). I’m working with a team to launch Payloop, a lightweight infrastructure layer that helps teams understand the real costs of deploying AI agents - across tasks, workflows, and customers. Here's a quick demo: https://www.youtube.com/watch?v=Z-GkSl_7imY Most companies today can't see what it actually costs to deploy their agents, making it nearly impossible to manage margins or price confidently. Payloop solves this with an elegant approach: just a single line of code gives you real-time visibility into cost…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
