Monitor

MODULE

Track every dollar, in real-time

Cost tracking per agent, smart alerts with AI diagnosis, forecast your end-of-month bill, and get automatic model recommendations.

Replay

MODULE

Debug in seconds, not hours

Step-by-step visual timeline of every agent session. See inputs, outputs, costs, and errors — then share with your team in one click.

Protect

MODULE

Guardrails that actually guard

Configurable content rules, automatic PII redaction, budget caps with kill switch, and compliance-ready audit logs.

Everything your agents need to behave.

One SDK. Three modules. Complete observability for AI agents in production.

CORE

Real-time Cost Tracking

See every API call, every token, every dollar — the moment it happens. Not at the end of the month.

AI

Smart Alerts

When something goes wrong, AI diagnoses why and suggests a fix. Not just 'threshold exceeded'.

SAVINGS

Cost Autopilot

Automatic model recommendations with estimated savings. 'Switch to gpt-4o-mini here — save $85/month.'

DEBUG

Session Replay

Visual step-by-step timeline of every agent run. Inputs, outputs, costs — all in one view.

SECURITY

Guardrails & PII

Block unwanted content, redact personal data automatically, kill switch when things go wrong.

FORECAST

Cost Forecast

Know your end-of-month bill before it arrives. Per agent, per team, with confidence intervals.

Up and running in 2 minutes.

No infrastructure. No config files. No code changes to existing agents.

Frequently asked questions

No. AgentShield tracks events asynchronously — your agent calls return immediately, with zero added latency. Events are batched and sent in the background.

OpenAI, Anthropic, Google (Gemini), Cohere, and any OpenAI-compatible API. Framework support: LangChain, CrewAI, AutoGen, LlamaIndex, and plain Python.

The SDK detects and redacts email addresses, phone numbers, credit card numbers, SSNs, and IP addresses before data leaves your environment. You can configure custom patterns.

Yes. Outbound webhooks (Pro+) let you forward events to Datadog, Grafana, PagerDuty, or any HTTP endpoint. AgentShield complements — not replaces — your existing tools.

Event data is stored per your plan: 7 days (Free), 30 days (Starter), 90 days (Pro), 1 year (Team). Session inputs/outputs are only stored if you opt in, and always with PII redacted.

AgentShield raises a BudgetExceededError in your code and optionally activates the kill switch — preventing further API calls until you lift it manually or the period resets.

Not yet. We are working on a self-hosted version for enterprise compliance needs. Contact us if that is a requirement.
