-You can use litellm through either:
-1. [LiteLLM Proxy Server](#litellm-proxy-server-llm-gateway) - Server (LLM Gateway) to call 100+ LLMs, load balance, cost tracking across projects
-2. [LiteLLM python SDK](#basic-usage) - Python Client to call 100+ LLMs, load balance, cost tracking

+You can use LiteLLM through either the Proxy Server or Python SDK. Both gives you a unified interface to access multiple LLMs (100+ LLMs). Choose the option that best fits your needs:

+# Azure AI Foundry Agents
+
+Call Azure AI Foundry Agents in the OpenAI Request/Response format.
+
+| Property | Details |
+|----------|---------|
+| Description | Azure AI Foundry Agents provides hosted agent runtimes that can execute agentic workflows with foundation models, tools, and code interpreters. |
+| Provider Route on LiteLLM | `azure_ai/agents/{AGENT_ID}` |
+| Provider Doc | [Azure AI Foundry Agents ↗](https://learn.microsoft.com/en-us/rest/api/aifoundry/aiagents/create-thread-and-run/create-thread-and-run) |
+
+## Quick Start
+
+### Model Format to LiteLLM
+
+To call an Azure AI Foundry Agent through LiteLLM, use the following model format.
+
+Here the `model=azure_ai/agents/` tells LiteLLM to call the Azure AI Foundry Agent Service API.
+
+```shell showLineNumbers title="Model Format to LiteLLM"
+azure_ai/agents/{AGENT_ID}
+```
+
+**Example:**
+- `azure_ai/agents/asst_abc123`
+
+You can find the Agent ID in your Azure AI Foundry portal under Agents.
+
+### LiteLLM Python SDK
+
+```python showLineNumbers title="Basic Agent Completion"

+
+## Environment Variables
+
+You can set the following environment variables to configure Azure AI Foundry Agents:
+
+| Variable | Description |
+|----------|-------------|
+| `AZURE_API_BASE` | The Azure AI Foundry project endpoint (e.g., `https://your-project.services.ai.azure.com`) |
+| `AZURE_API_KEY` | Your Azure AI Foundry API key |
+
+```bash
+export AZURE_API_BASE="https://your-project.services.ai.azure.com"
+export AZURE_API_KEY="your-api-key"
+```
+
+## Conversation Continuity (Thread Management)
+
+Azure AI Foundry Agents use threads to maintain conversation context. LiteLLM automatically manages threads for you, but you can also pass an existing thread ID to continue a conversation.
+
+```python showLineNumbers title="Continuing a Conversation"
+import litellm
+
+# First message creates a new thread
+response1 = await litellm.acompletion(
+    model="azure_ai/agents/asst_abc123",

+    api_base="https://your-project.services.ai.azure.com",
+    api_key="your-api-key",
+)
+
+# Get the thread_id from the response
+thread_id = response1._hidden_params.get("thread_id")
+
+# Continue the conversation using the same thread
+response2 = await litellm.acompletion(
+    model="azure_ai/agents/asst_abc123",

+LiteLLM ships with a native integration for [HiddenLayer](https://hiddenlayer.com/). The proxy sends every request/response to HiddenLayer’s `/detection/v1/interactions` endpoint so you can block or redact unsafe content before it reaches your users.
+
+## Quick Start
+
+### 1. Create a HiddenLayer project & API credentials
+
+**SaaS (`*.hiddenlayer.ai`)**
+
+1. Sign in to the HiddenLayer console and create (or select) a project with policies enabled.
+2. Generate a **Client ID** and **Client Secret** for the project.

+      default_on: true
+```
+
+### Required parameters
+
+- **`guardrail`**: Must be set to `hiddenlayer` so LiteLLM loads the HiddenLayer hook.
+
+### Optional parameters
+
+- **`api_base`**: HiddenLayer REST endpoint. Defaults to `https://api.hiddenlayer.ai`, but point it at your self-hosted instance if you have one.
+- **`auth_url`**: Authentication url for hiddenlayer. Defaults to `https;//auth.hiddenlayer.ai`.
+- **`mode`**: Control when the guardrail runs (`pre_call`, `post_call`, `during_call`).
+- **`default_on`**: Automatically attach the guardrail to every request unless the client opts out.
+- **`hl-project-id` header**: Routes scans to a specific HiddenLayer project.
+- **`hl-requester-id` header**: Sets `metadata.requester_id` for auditing.
+
+## Environment variables
+
+```shell
+# SaaS
+export HIDDENLAYER_CLIENT_ID="hl_client_id"
+export HIDDENLAYER_CLIENT_SECRET="hl_client_secret"
+
+# Shared (SaaS or self-hosted)
+export HIDDENLAYER_API_BASE="https://api.hiddenlayer.ai"
+```
+
+Set only the variables you need, self-hosted installs can leave the client ID/secret unset and just configure `HIDDENLAYER_API_BASE`.

 :::
 
+### Fail-Open Configuration
+
+By default, the PANW guardrail operates in **fail-closed** mode for maximum security. If the PANW API is unavailable (timeout, rate limit, network error), requests are blocked. You can configure **fail-open** mode for high-availability scenarios where service continuity is critical.
+
+```yaml

+  - guardrail_name: "panw-high-availability"
+    litellm_params:

+      timeout: 5.0                 # Shorter timeout for fail-open
+```
+
+**Configuration Options:**
+
+| Parameter | Value | Behavior |
+|-----------|-------|----------|
+| `fallback_on_error` | `"block"` (default) | **Fail-closed**: Block requests when API unavailable (maximum security) |
+| `fallback_on_error` | `"allow"` | **Fail-open**: Allow requests when API unavailable (high availability) |
+| `timeout` | `1.0` - `60.0` | API call timeout in seconds (default: `10.0`) |
+
+**Error Handling Matrix:**
+
+| Error Type | `fallback_on_error="block"` | `fallback_on_error="allow"` |
+|------------|----------------------------|----------------------------|
+| 401 Unauthorized | Block (500) | Block (500) ⚠️ |
+| 403 Forbidden | Block (500) | Block (500) ⚠️ |

+| 5xx Server Error | Block (500) | Allow (`:unscanned`) |
+| Content Blocked | Block (400) | Block (400) |
+
+⚠️ = Always blocks regardless of fail-open setting 
+
+:::warning Security Trade-Off
+Enabling `fallback_on_error="allow"` reduces security in exchange for availability. Requests may proceed **without scanning** when the PANW API is unavailable. Use only when:
+- Service availability is more critical than security scanning
+- You have other security controls in place
+- You monitor the `:unscanned` header for audit trails
+
+**Authentication and configuration errors (401, 403, invalid profile) always block** - only transient errors (429, timeout, network) trigger fail-open behavior.
+:::
+
+**Observability:**
+
+When fail-open is triggered, the response includes a special header for tracking:
+
+```
+X-LiteLLM-Applied-Guardrails: panw-airs:unscanned
+```
+
+This allows you to:
+- Track which requests bypassed scanning
+- Alert on unscanned request volumes
+- Audit compliance requirements

+  - You can configure specific entity types for PII detection and decide how to handle each entity type (mask or block).
+- **Detection Confidence Score Threshold**
+  - You can also provide an optional confidence score threshold at which detections will be passed to the anonymizer. Entities without an entry in `presidio_score_thresholds` keep all detections (no minimum score).
+- **Scope**

-### Configure Entity Types in config.yaml
+      - `input`: only user → model content is scanned
+      - `output`: only model → user content is scanned
+      - `both` (default): scan both directions
+
+    **What about `output_parse_pii`?**  
+    This flag only un-masks tokens back to the originals after the model call; it does not run Presidio detection on outputs. Use `presidio_filter_scope: output` (or `both`) when you want Presidio to actively scan and mask the model’s response before it reaches the user.
+
+    **When to pick input vs output:**
+    - `input`: Protect upstream providers; strip PII before it leaves your boundary.
+    - `output`: Catch PII the model might generate or leak back to users.
+    - `both`: End-to-end protection in both directions.
