One platform for complete AI agent observability
Every LLM call, tool use, and decision is recorded immutably. No event is ever lost or altered.
Events flow in milliseconds. Watch your agents think in real time with zero latency.
Break down spend by agent, model, and session. Eliminate runaway costs before they happen.
Step through any agent session like a debugger. Inspect every payload, every decision.
Automatic alerts when agents behave unexpectedly — cost spikes, loops, or silent failures.
Generate audit-ready reports mapped to EU AI Act Articles 9, 13, 14 & 17, SOC 2 Type II AI controls, and ISO 42001 clauses — in one click. Hand them directly to auditors, legal, or enterprise procurement.
Every agent action is SHA-256 hashed and chained. Any attempt to alter historical records is cryptographically impossible — giving regulators and auditors a trail they can actually trust.
Pause high-risk agent actions for human review before execution. Meet EU AI Act Article 14 mandates with a built-in approval workflow — approve, reject, or modify any agent decision in real time.

High-risk AI actions shouldn't execute unchecked. AgentLedger intercepts agent decisions and routes them through a real-time approval queue.
Every action is cryptographically linked. Tamper with one block, and the entire chain breaks.
