Agent Hack Auto-Detection API

Real-time security scanning for AI agent pipelines. Detect prompt injection, tool abuse, data exfiltration, and runaway loops — all with deterministic, rule-based detection. No LLM in the loop.

API Overview

Agent Hack Auto-Detection API provides 8 endpoints covering every step of an agentic pipeline:

Method	Endpoint	Description	Tier
GET	`/health`	Health check — returns status, version, timestamp	Free (no auth)
POST	`/scan/prompt`	Scan a user prompt for injection, escalation, exfiltration	Basic
POST	`/scan/toolcall`	Validate a tool call against allowlists and abuse patterns	Basic
POST	`/scan/plan`	Analyze an agent plan for runaway steps and dangerous directives	Pro
POST	`/scan/output`	Scan model output for leaked secrets, PII, and unsafe content	Pro
POST	`/scan/session`	Full gate — scan prompt + tools + plan + output in one call	Pro
GET	`/policies`	List built-in policy profiles and their metadata	Ultra
POST	`/policies/evaluate`	Full session scan with detailed policy decision explanation	Ultra

Pricing Tiers

Tier	Price	Rate Limit	Endpoints Included
Basic	Free	200 req/day	`/health`, `/scan/prompt`, `/scan/toolcall`
Pro	$29/mo	5,000 req/day	All Basic + `/scan/plan`, `/scan/output`, `/scan/session`
Ultra	$99/mo	50,000 req/day	All Pro + `/policies`, `/policies/evaluate`
Mega	$299/mo	250,000 req/day	All Ultra + highest payload limits

Scoring & Verdicts

Every scan endpoint returns a riskScore (0–1) and a verdict:

allow — riskScore < 0.30 — Safe to proceed
review — riskScore 0.30–0.65 — Flag for human review
block — riskScore > 0.65 — Block the request

Formula: riskScore = sum(signal_weights) / (sum(signal_weights) + 10)

Response Headers

All authenticated endpoints return standard rate-limit headers:

Header	Description
`X-RateLimit-Limit`	Requests allowed per window
`X-RateLimit-Remaining`	Requests remaining in current window
`X-RateLimit-Reset`	Unix timestamp when the window resets
`X-Request-Id`	Unique request identifier (UUID v4)
