AgentLedger gives AI agents a sandbox to test payment flows before they spend a cent in production. Step through transactions, inspect payloads, catch the bugs — before your agent maxes out a Stripe limit on a bad loop.

Every AI agent that accesses paid APIs — Twilio, AWS, Stripe, Sapiom, any of them — needs to be tested. But right now there's no staging environment for agent financial flows. You either run against production credentials, or you don't test at all.
One bad loop. One misread response. One agent that decides to re-try a failed charge four times. That's a $400 bill from your payment provider — before you've shipped anything.
Every payment call runs in a fully isolated sandbox. Same API surface as production — same payloads, same responses — but zero real charges. Your agent can't tell the difference. Neither can your budget.
Watch every transaction happen in sequence. Inspect request payloads, response codes, latency, and cost — all timestamped and linked. Pause, resume, or replay any trace to reproduce exactly what your agent did.
Configure per-agent spending caps, rate limits, and blocked vendor lists. Catch a misbehaving agent before it burns through your sandbox budget — or before it reaches production with no brakes.
Full transaction history for every agent session — what ran, when, how much it cost, and what the API returned. Export to your observability stack or replay a session exactly as it happened, in any environment.
AgentLedger intercepts your agent's financial API calls and routes them through a sandboxed proxy. You see everything — the raw requests your agent is sending, the responses it's receiving, the cost it's accumulating, and every policy decision being made in real time.
No code changes required. Point your agent's SDK at the AgentLedger proxy and the sandbox activates automatically. When you're ready to go to production, flip the switch — same API calls, real money.
