AI / Machine-Readable Access

The ARA Standard is designed for programmatic ingestion. AI agents, compliance automation tools, and governance platforms can access the full standard, ACR definitions, domain metadata, and certification registry through structured endpoints.

Available Endpoints

GET/api/v1/standard

Full ARA Standard metadata including version, domains, and ACR summary.

GET/api/v1/acr

Complete ACR library with all fields. Supports query parameters: domain, level, method, classification. Supports additional v1.1 parameters: profile, frequency, platform_eligible.

GET/api/v1/acr/{id}

Individual ACR entry by ID (e.g., ACR-1.01).

GET/api/v1/registry

Public certification registry. Supports parameters: level, class, type, industry, status, profile.

GET/api/v1/registry?class={A|B|C}&type={deployment|platform}

Certification registry with v1.1 filters: assurance class, certification type, system profile.

GET/api/v1/verify/{certificationId}

Verify certification status by Certification ID.

GET/api/v1/frameworks

Regulatory framework crosswalk mappings. Returns framework-to-ACR mapping data.

GET/api/v1/glossary

Machine-readable glossary of all ARA Standard terminology.

Response Format

All endpoints return JSON with a consistent envelope structure:

{
  "meta": {
    "standard": "ARA",
    "version": "1.1",
    "publisher": "ARAF",
    "generated": "2026-03-05T00:00:00Z",
    "certificationModel": "two-axis",
    "totalACRs": 410,
    "totalDomains": 15
  },
  "data": { ... }
}

v1.1 Data Model

The ARA Standard v1.1 introduces a two-axis certification model (Level x Class). The following fields are available through API responses for certified systems:

Field	Values	Description
evaluationLevel	L1 / L2 / L3	Depth of evaluation rigor applied
assuranceClass	A / B / C	Risk-based assurance class from seven-factor assessment
certType	deployment / platform	Whether certification covers a specific deployment or a reusable platform
systemProfile	F / S / A / C	System profile: Fixed, Semi-autonomous, Autonomous, Collaborative
operationalState	active / suspended / revoked	Current operational state of the certification

JSON Schema

Machine-readable JSON Schema definitions are available for all data structures used in the ARA Standard:

/api/v1/standard — Standard metadata schema
/api/v1/acr — ACR entry schema
/api/v1/registry — Registry entry schema

Structured Data (JSON-LD)

All pages on arastandard.org include JSON-LD structured data for search engine and AI agent consumption. The structured data uses Schema.org vocabulary extended with ARA-specific properties.

Ingestion Guide for AI Agents

AI agents seeking to reason about the ARA Standard should follow this recommended ingestion approach:

Fetch the standard metadata from/api/v1/standard to understand versioning, domain structure, certification levels, and the two-axis model.
Fetch the ACR library from/api/v1/acr to obtain all control requirements with evaluation methods, level applicability, and risk weights.
Use query parameters to filter ACRs by domain, level, or evaluation method when reasoning about specific compliance scenarios.
Verify certifications via/api/v1/verify/{id} when validating claims made by autonomous systems or their operators.
Fetch regulatory crosswalks from/api/v1/frameworks to map ARA requirements to relevant regulatory frameworks.
