Tokenwall

What it does

Tokenwall stops AI agent loops before the dollar ceiling trips. Reserve-then-commit budgeting per action. Per-user, per-task, per-agent attribution. Built by someone who runs treasury at tier-1 banks. Free during private beta, first 20 builders.

Tokenwall was a one-week experiment, a circuit breaker for AI agents. It didn

For one week in June 2026, this was a circuit breaker for AI agents. I built it, launched it on Product Hunt, and set real pass-or-fail criteria before I started. It didn't find its market, so I closed it on purpose instead of letting it limp. No drama. That's just how most experiments end when you're honest with yourself about the result. Interest is not demand. A lot of sharp people told me the idea was clever. Nobody needed it badly enough to hand over an email or a dollar. Those are completely different signals, and I won't confuse them again. Thanks to everyone who took a look, kicked the tires, or argued with me about how you actually catch a loop at iteration 3. That part was…from tokenwall.dev

  • AgentGuard – Auto-kill AI agents before they burn through your budget2025 · github.com · ▲47

    Your 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…

    Hi guys, am building SecureLend.ai and when working on our underwriting agents (free trial, paid after) I had issues with seamless payment options. Of course I looked at x402 which I believe is a great protocol but not a fan of a) sharing private keys with the agent b) having a human in the loop or c) similar workaround e.g. pre-funded wallets So I started building out a solution. For my use case it was important to not only have stablecoins but also a fiat rail which is now implemented using Stripe. Initially I build a mandate system internally but am very glad and big shoutout to the guys…

  • Tokencap – Token budget enforcement across your AI agentsApr 2026 · github.com · ▲7

    I built this after hitting the same wall repeatedly — no good way to enforce token budgets in application code. Provider caps are account-level and tell you what happened, not what is happening. Two ways to add it: # Direct client wrapper client = tokencap.wrap(anthropic.Anthropic(), limit=50_000) # LangChain, CrewAI, AutoGen, etc. tokencap.patch(limit=50_000) Four actions at configurable thresholds: WARN, DEGRADE (transparent model swap), BLOCK, and WEBHOOK. SQLite out of the box, Redis for multi-agent setups. One design decision worth mentioning: tokencap tracks tokens, not dollars. Token…

  • Today, I’m proud to announce Homebrew 6.0.0. 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). Happy to discuss any questions here!
