Tickstem
Give your AI agent a spending limit it can't break.
Autonomous agents that can spend money are powerful — and terrifying without guardrails. Tickstem is the authorization layer that caps what an agent can spend, requires approval above a threshold you set, and records every request. One API key. No money moves through us.

You hand an AI agent a credit card or an API that moves money, and you're trusting a probabilistic system not to loop, hallucinate a purchase, or get prompt-injected into draining a budget. There's no native "this agent may spend at most €200 this month, and anything over €50 needs my sign-off." So most teams either don't let agents transact at all, or bolt on brittle one-off checks.
How it works
Grant a budget
Register an agent and grant it spending authority: an amount, a period, and an auto-approve threshold — e.g. €200/month, auto-approve under €50.
The agent requests to spend
Before it transacts, the agent asks Tickstem for authorization. Under the threshold it's approved instantly; over it, you're notified and approve or reject.
Your system verifies and settles
Your payment code checks the returned authorization token before paying, then marks it settled. Every request — approved or denied — is on the audit trail.
Why it's different
- A hard cap, not a suggestion. The limit is enforced server-side. A runaway agent hits the ceiling and stops — it can't talk its way past it.
- Human-in-the-loop where it matters. Small spends flow automatically; anything above your threshold waits for approval. You're not babysitting every transaction.
- Full audit trail. Every authorization request, approval, and rejection is recorded — so you can answer "what did the agent try to spend, and when?"
- It pairs with monitoring. The same Tickstem key gives the agent a schedule, a heartbeat, and uptime checks — so you can watch the agent you just gave a budget to.
