What it does
Your AI agents pay for APIs, tools, and compute on their own. One bug or prompt injection can drain the wallet in minutes. Burnwatch learns each agent's normal spend and alerts you the second something looks wrong. Never touches your keys. pip install burnwatch.
Spend monitoring for AI agents. Burnwatch baselines each agent
Agents now run up real bills on their own: API calls, tools, compute, and increasingly onchain (x402) payments, with no human clicking "confirm." One bad loop or prompt injection and they keep spending until you see the invoice. Your bank flags a weird charge in seconds. Nobody does that for an agent that just got compromised. Burnwatch learns each agent's normal spend and alerts the instant it goes wrong. The big platforms will sell you per-transaction limits — but only if your agent lives entirely inside their walled garden, and only if the attacker spends in obvious round numbers. A compromised agent doesn't. It bleeds you in thousands of "normal-looking" micro-payments. No custody…from burnwatch.dev

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.

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…

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate).

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
