In a typical production LLM architecture, Credo AI sits as a policy enforcement point after inference but before the response is delivered. It intercepts the raw LLM output (from providers like OpenAI, Anthropic, or your own fine-tuned model) and programmatically evaluates it against your configured content, fairness, data privacy, and compliance policies. Think of it as a Policy-as-Code gateway that can block, redact, or flag outputs in real-time based on rules you define. This is critical for integrating AI into regulated workflows in finance, healthcare, or legal sectors where uncontrolled outputs carry significant risk.
Integration
AI Integration with Credo AI Policy Enforcement

Where Credo AI Fits in Your LLM Stack
Credo AI acts as the runtime guardrail and governance layer between your LLM applications and your end-users or downstream systems.
Implementation involves deploying Credo AI's policy engine as a sidecar service or a dedicated microservice in your inference pipeline. Your application code sends the LLM's prompt and completion to the Credo AI API, which returns a governance verdict (ALLOW, BLOCK, FLAG_FOR_REVIEW) and an enriched audit log. For high-throughput applications, this can be integrated via asynchronous queues to avoid adding latency to the user experience. Key integration surfaces include:
- Pre-production: Connecting Credo AI to your CI/CD pipeline to run policy checks on new prompt versions or model deployments.
- Runtime: Embedding the Credo AI SDK or calling its REST API within your LangChain callbacks, FastAPI routes, or agent orchestration logic.
- Post-hoc: Streaming inference logs from your monitoring tools (like LangSmith or Arize AI) to Credo AI for batch analysis and compliance reporting.
Rollout is typically phased, starting with logging-only mode to baseline policy violations without blocking, then moving to soft enforcement (flagging for human review), and finally hard enforcement for critical policies. Governance teams use Credo AI's dashboard to define policies—such as "block any output containing PII" or "flag potential regulatory advice"—and map them to specific LLM applications. The integration creates an immutable audit trail that links every decision to a specific policy, user session, and model version, which is essential for internal reviews and regulatory examinations. For teams already using platforms like Weights & Biases for experiment tracking, Credo AI complements by adding the governance and risk dimension to the MLOps lifecycle.
Credo AI Integration Surfaces and Policy Types
API-Level Policy Enforcement
Integrate Credo AI's policy engine directly into your LLM inference pipeline. This surface intercepts requests and responses between your application and model providers (OpenAI, Anthropic, etc.) to evaluate outputs against configured policies before they reach end-users.
Key Integration Points:
- Pre-Completion Hooks: Inject Credo AI's evaluation SDK into your application's LLM calling logic. The SDK sends the prompt and generated completion to Credo for policy scoring.
- Post-Completion Validation: For streaming responses, buffer the final output and submit it for a blocking validation check. Failed checks can trigger a re-generation request with a corrected system prompt or a fallback message.
- Webhook Callbacks: For asynchronous processing, configure your LLM service to send completion payloads to a webhook endpoint that forwards them to Credo AI's API, logging the policy verdict for audit.
This layer is critical for enforcing content safety, preventing data leakage, and blocking outputs that violate fairness thresholds in real-time user interactions.
High-Value Use Cases for Runtime Policy Enforcement
Credo AI's policy engine acts as a runtime guardrail, programmatically evaluating LLM outputs against your organization's content, fairness, and data privacy standards before they reach users or downstream systems. These patterns show where to integrate policy checks for maximum control and compliance.
Customer-Facing Chatbot Content Guardrails
Intercept every chatbot response before it's sent to the user. Enforce policies against generating harmful content, unsubstantiated claims, or leaking internal data. Integrate Credo AI's API as a sidecar service to your chatbot's inference endpoint, routing outputs for policy scoring and blocking violations.
Automated Document Generation & Review
Govern LLM-generated contracts, marketing copy, or internal reports. Use Credo AI to scan drafts for policy violations like non-compliant clauses, speculative financial projections, or inclusion of sensitive data. Integrate into content approval workflows in platforms like SharePoint or Google Docs via webhooks.
RAG-Powered Agent Response Validation
Add a policy check layer after your Retrieval-Augmented Generation (RAG) system produces an answer. Validate that the final synthesis is grounded in the provided context and doesn't hallucinate or violate fairness policies. This integration sits between your RAG pipeline's final output and the user-facing API.
Financial or Healthcare Decision Support
For high-stakes domains like loan underwriting or clinical note summarization, enforce strict fairness and accuracy policies. Integrate Credo AI to audit LLM-suggested decisions or summaries, flagging outputs that show potential bias against protected classes or that contradict source data.
Internal Copilot Tool-Calling Governance
Govern agents that execute actions via API (e.g., sending emails, updating CRM). Use Credo AI to evaluate the intent and generated parameters of a tool call before execution. Block actions that would violate data access policies, send communications to unauthorized parties, or create non-compliant records.
Personalized Marketing Content Compliance
Screen dynamically generated product descriptions, email subject lines, or ad copy for regulatory compliance (e.g., FTC guidelines, GDPR). Integrate Credo AI's policy checks into the rendering pipeline of marketing platforms like Braze or Marketo, preventing non-compliant variants from being deployed.
Example Guardrail Workflows with Credo AI
These workflows demonstrate how to integrate Credo AI's policy engine as a runtime guardrail layer for LLM applications. Each example shows a concrete automation that blocks, flags, or redirects outputs before they reach end-users or downstream systems.
Trigger: A customer support chatbot (e.g., in Zendesk or Salesforce Service Cloud) generates a response to a user query.
Context Pulled: The raw LLM completion, the conversation history, and metadata about the user's service tier.
Credo AI Action: The completion is sent to Credo AI's policy engine via its API. A pre-configured Content Safety Policy evaluates the text against rules for:
- Hate speech and harassment
- Unverified medical or financial advice
- Leakage of internal system prompts or PII
- Inappropriate emotional tone for a support context
System Update:
- If the policy check passes, the response is delivered to the user.
- If the policy check fails, the response is blocked. A fallback action is triggered:
The ticket is automatically escalated, and the violation is logged to Credo AI's audit trail with the full context.json{ "action": "block_and_redirect", "fallback_message": "I need to connect you with a human agent for further assistance.", "violated_policy_id": "content_safety_001", "audit_log_id": "audit_xyz789" }
Human Review Point: All blocked interactions are routed to a supervisor dashboard in Credo AI for weekly review to calibrate policy thresholds and identify new edge cases.
Implementation Architecture: The Policy Enforcement Layer
Integrating Credo AI's policy engines as a runtime guardrail layer to programmatically block, flag, or modify LLM outputs that violate content, fairness, or data privacy policies before they reach end-users or downstream systems.
The core integration pattern places Credo AI's policy engine as a runtime filter between your LLM inference endpoint (e.g., OpenAI, Anthropic, a fine-tuned model) and your application's API or user interface. For each LLM call, the raw completion is intercepted and sent to Credo AI's assessment API, which evaluates it against your configured policy library. Policies can check for:
- Content Safety: Blocking outputs containing hate speech, violence, or disallowed topics.
- PII & Data Privacy: Detecting and redacting personally identifiable information (PII) like credit card numbers or health data before the response is logged or displayed.
- Fairness & Bias: Flagging outputs that show statistical disparities across protected attributes (e.g., gender, ethnicity) in high-stakes decisions like loan approvals.
- Hallucination & Factuality: Using Credo AI's integrations with grounding sources to score answer veracity against trusted knowledge bases.
This layer acts as a circuit breaker, preventing policy violations from propagating. Violations can trigger actions defined in your policy: block the response entirely, return a sanitized version, route the query for human review, or log the incident to an audit trail.
Implementation requires configuring two primary touchpoints: the policy definition layer in Credo AI's console and the runtime enforcement API in your application code. A typical architecture involves:
- Policy Configuration: Define and test policies in Credo AI's interface, mapping controls to specific LLM use cases (e.g., a stricter fairness policy for a recruiting chatbot vs. a marketing copy generator).
- API Integration: Wrap your LLM client calls with a service that calls Credo AI's
/evaluateendpoint. Use a non-blocking, asynchronous pattern to minimize latency impact. - Audit Logging: Configure Credo AI to stream all evaluation events—including inputs, outputs, policy checks, and violation details—to your SIEM (e.g., Splunk) or data lake for immutable audit trails.
- Fallback Handling: Design fallback logic for when the policy engine is unavailable (e.g., fail open with logging or fail closed to block all outputs) based on your risk tolerance.
For high-throughput applications, deploy the policy engine as a sidecar container or service mesh filter alongside your LLM microservice to enforce governance without modifying core application logic.
Rollout and governance for this layer follow a phased approach. Start with monitoring-only policies in a staging environment to establish a baseline violation rate without impacting users. Then, gradually enforce blocking policies for the highest-risk violations (e.g., clear PII leakage) in production, using feature flags to control the rollout percentage. Credo AI's dashboards provide real-time visibility into policy violation rates, helping you tune sensitivity thresholds and identify patterns that may require prompt engineering or model retraining. This integration creates a continuous compliance feedback loop, where policy violations detected at runtime automatically generate tickets in systems like Jira or ServiceNow for the responsible AI team to investigate and remediate.
Code and Payload Examples
Validating Inputs Before LLM Call
Before sending a user query to an expensive LLM, you can use Credo AI's API to screen the input for policy violations, such as toxic language or attempts to extract PII. This pre-call check prevents wasted tokens and potential policy breaches.
pythonimport requests # Example: Screening a user query with Credo AI query = "Tell me the credit card numbers for customer John Doe." credo_check_url = "https://api.credo.ai/v1/policies/check" headers = {"Authorization": f"Bearer {CREDO_API_KEY}"} payload = { "content": query, "policy_ids": ["pii-detection", "toxic-content"], "action": "screen" } response = requests.post(credo_check_url, json=payload, headers=headers) result = response.json() if result.get("violations"): # Block the call, return a safe message safe_response = "I cannot process that request." log_violation(result["violations"], "input_screening") else: # Proceed with LLM call llm_response = call_openai(query)
This pattern is ideal for high-volume, public-facing chatbots where input quality is unpredictable.

Governance, Audit, and Phased Rollout
Integrating Credo AI's policy engine requires a structured approach to risk management, evidence collection, and controlled release.
A production integration with Credo AI typically follows a three-layer architecture: 1) your LLM application layer (e.g., a LangChain agent or custom API), 2) the Credo AI Policy Engine acting as a runtime guardrail, and 3) your core systems of record. The policy engine intercepts LLM requests and responses, evaluating them against configured content, fairness, and data privacy policies. Violations can trigger programmatic actions like blocking the output, redacting sensitive data, or routing the decision for human review. This layer is integrated via API calls or SDK hooks within your inference pipeline, ensuring all traffic is evaluated before reaching end-users or downstream systems like Salesforce, ServiceNow, or internal databases.
Rollout is phased, starting with shadow mode where policies are evaluated in parallel but don't block production traffic, generating initial risk reports and tuning policy thresholds. This is followed by a canary release to a low-risk user segment or a single use case (e.g., internal HR chatbot), where enforcement is active but with a high-confidence threshold and a defined human-in-the-loop escalation path. Full production rollout occurs only after validating policy effectiveness, monitoring for false positives/negatives, and ensuring the integration's latency and reliability meet SLAs. Each phase is governed by a change advisory board (CAB) process, with approvals logged in Credo AI's audit trail.
For audit and compliance, the integration automatically captures immutable logs of every policy check—including the input prompt, the LLM's raw output, the applied policy, the evaluation result, and any enforcement action. These logs are essential for demonstrating control effectiveness to internal audit teams and external regulators. Credo AI can be configured to generate standardized reports mapping these logs to frameworks like the NIST AI RMF or EU AI Act, pulling evidence from linked systems like Weights & Biases for model lineage and Arize AI for performance monitoring. This creates a closed-loop governance system where policy violations in production can trigger automated retraining pipelines or prompt engineering updates, managed through integrated ticketing systems like Jira or ServiceNow.

Frequently Asked Questions
Below are detailed walkthroughs for common integration patterns that connect LLM applications to Credo AI's policy enforcement engine, illustrating how runtime guardrails are applied in production.
This workflow intercepts LLM-generated responses before they reach the end-user, applying policy checks for harmful content, PII leakage, and brand safety.
- Trigger: A user query is processed by your LLM application (e.g., a chatbot built with LangChain or a custom service). The application generates a candidate response.
- Context/Data Pulled: Before returning the response, the application calls the Credo AI Policy Engine API, sending the
user_query,llm_response, and relevantcontext(e.g., user segment, interaction history). - Model/Agent Action: Credo AI evaluates the response against active policies (e.g., "No profanity," "No unverified medical advice," "Mask all PII"). Policies can use a combination of classifiers, regex patterns, and secondary LLM checks.
- System Update: The API returns a structured result:
json
{ "policy_decision": "BLOCK", "violated_policies": ["PII_DETECTION"], "safe_alternative": "I can see your account details are on file. For security, I can't share them here. Please use the secure portal or call support." } - Human Review Point: If configured, blocked responses with high severity are logged to a Credo AI case management queue for later review by a compliance officer. The chatbot serves the
safe_alternativetext to the user.
