Integration Documentation

Complete reference for AgentGuard runtime protection, approvals, audit ingestion, and supply-chain scanning APIs.

Authentication

All API requests require authentication via the X-API-Key header. You can generate and manage your keys from the API Keys dashboard.

curl -H "X-API-Key: ag_live_your_key_here" \
  https://agentguard.gopluslabs.io/api/v1/scan

Alternative: You can also authenticate using a Bearer token in the Authorization header: Authorization: Bearer ag_live_your_key_here

Base URL

https://agentguard.gopluslabs.io

Development: For local development use http://localhost:3000 as the base URL. All endpoint paths remain the same.

Runtime Protection

Connected local guards enforce policy before risky actions, cache policy for offline use, and sync only redacted audit events to AgentGuard Cloud.

Evaluate action

POST /api/v1/actions/evaluate

Fetch effective policy

GET /api/v1/policies/effective

Sync redacted audit events

POST /api/v1/events/ingest

Review approvals and session timelines

GET /api/v1/approvals

curl -fsSL https://agentguard.gopluslabs.io/install.sh | bash

Scan Agent Supply Chain

POST/api/v1/scanAuth Required

Scan skills, tools, plugins, MCP servers, or agent code before they enter a runtime. Submit raw code content and receive threat analysis with risk scoring, detected threats, and permission analysis.

X-API-Key	Your API key

Body Parameters

Name	Type	Required	Description
content	string	Yes	The raw source code or manifest content to scan
ai	boolean	No	Enable AI-powered deep analysis (default: false). Adds ~5-30s processing time.

Example Request

curl -X POST https://agentguard.gopluslabs.io/api/v1/scan \

Rate Limiting

API requests are rate-limited using a sliding window algorithm to ensure fair usage and service stability. Limits are applied per API key.

Tier Limits

Tier	Protected Actions / Month	Requests / Minute	API Keys
Free	100	5	1
Pro	5,000	50	5
Enterprise	Unlimited	200	20

Response Headers

X-RateLimit-Limit: 50
X-RateLimit-Remaining: 47
X-RateLimit-Reset: 1740600000

X-RateLimit-Limit -- Maximum requests allowed in the current window
X-RateLimit-Remaining -- Requests remaining in the current window
X-RateLimit-Reset -- Unix timestamp when the rate limit window resets

Rate Limited Response 429 Too Many Requests

{
  "error": {
    "code": "RATE_LIMIT_EXCEEDED",
    "message": "Rate limit exceeded. Please wait before making another request.",
    "retryAfter": 32
  }
}

Error Codes

The API uses standard HTTP status codes. All error responses follow a consistent shape with a machine-readable error code and a human-readable message.

HTTP Code	Error Code	Description
400	VALIDATION_ERROR	Invalid request parameters
401	AUTHENTICATION_ERROR	Invalid or missing API key
402	QUOTA_EXCEEDED	Monthly protection quota exceeded
403	FEATURE_NOT_AVAILABLE	Feature requires higher tier
404	NOT_FOUND	Resource not found
429	RATE_LIMIT_EXCEEDED	Rate limit exceeded
500	INTERNAL_ERROR	Server error

Error Response Shape

{
  "error": {
    "code": "VALIDATION_ERROR",
