Sentinel Integration and Marketplace - SIM
The governed execution and orchestration layer for AI agents
Any agent. Any provider. One API key. Sentinel handles auth, policy enforcement, budget controls, orchestration, and billing — completely invisible to your agent.
Everything your agent needs. Nothing it doesn't.
Sentinel sits between your agent and every external service. Your agent just calls tools — we handle the rest.
Auth & Security
- ✓JWT + agent API key authentication
- ✓AES-256 credential encryption
- ✓Brute-force protection & token rotation
- ✓Role-based access control (RBAC)
Policy & Budget
- ✓Per-agent spend limits & alerts
- ✓Tool and provider restrictions
- ✓Rate limiting per user/agent
- ✓Real-time budget enforcement
Provider Routing
- ✓One API key routes to any provider
- ✓OpenAI, Anthropic, Gemini, Perplexity, Mistral, Cohere, GitHub, Vercel, Railway, Stripe, Resend, Replicate
- ✓Cost estimation before execution
- ✓Full audit trail on every call
Chain Orchestration
- ✓Agent-on-agent execution with sentinel.run()
- ✓Sequential step chains with output piping
- ✓Automatic retry + provider failover per step
- ✓Budget enforcement halts chains before overspend
Up and running in 4 steps
One SDK. Any provider. Full control. Your keys stay yours.
Install the SDK & sign up
Install sentinel-sim from PyPI or npm. Sign up on the dashboard, verify your email, and generate a Sentinel API key.
pip install sentinel-sim # Sign up at sentinel-sim.com/dashboard # Generate a key → sk_sentinel_xxxxxxxxxx
Call any provider with your own keys
Use the SDK to route tool calls through Sentinel. Pass your provider keys per-request — we never store them.
from sentinel import Sentinel
client = Sentinel(api_key="sk_sentinel_...")
result = client.execute(
"chat", "openai",
{"messages": [{"role": "user",
"content": "hello"}]},
provider_credentials={
"openai": "sk-proj-YOUR_KEY"
}
)Sentinel handles everything else
Auth, policy checks, budget enforcement, provider routing, observability, and a full audit trail — all automatic.
→ auth → policy → budget check → route to provider → execute → persist → observe → respond ✓ execution_id: "c82e09da..." ✓ model: "gpt-5.4" ✓ tokens: 16, cost: $0.0001 ✓ duration: 1.7s
Chain agents together
One call triggers a multi-step chain across providers. GPT writes code, GitHub pushes it, Vercel deploys it — all orchestrated.
result = client.run(agent_id=1, payload={
"task": "build and deploy a page"
})
# Step 1: OpenAI generates code
# Step 2: GitHub creates repo + pushes
# Step 3: Vercel deploys from repo
# Retry + failover on every step
# Budget enforced — halts if exceeded
✓ status: "completed"
✓ steps: 3/3, cost: $0.02
✓ output: { url: "https://..." }Every service your agent needs. Already integrated.
