The open standard for the agentic web.
The Foundry Standard defines what it means for a website to be AI agent-ready. Run The Assay to get your score. Earn your certification.
Three domains. One standard.
The Foundry Standard evaluates every site across three weighted domains. Each reflects a distinct aspect of AI agent compatibility.
Can AI agents actually navigate and extract meaning from your site? This domain covers structured data, semantic markup, machine-readable metadata, and the presence of agent-friendly artifacts like agents.json and llms.txt.
- Structured data (JSON-LD, schema.org)
- Semantic HTML and ARIA roles
- agents.json publication
- llms.txt presence and format
- Crawlability and robots.txt hygiene
Does your site handle AI agent interactions safely, without introducing risk to users or operators? This domain covers authentication patterns, rate limiting, input validation, and resistance to prompt injection vectors.
- Authentication and authorization controls
- Rate limiting and abuse prevention
- Input sanitization and output encoding
- Prompt injection surface area
- HTTPS and transport security
Does your site behave responsibly when AI agents act on its behalf? The highest-weighted domain covers consent surfaces, reversibility of agent-initiated actions, transparency disclosures, and human-in-the-loop checkpoints.
- Consent and disclosure patterns
- Reversibility of agent-triggered actions
- Human-in-the-loop checkpoints
- Transparency about AI involvement
- Data minimization for agent interactions
Certification tiers
Earn certification by meeting the scoring thresholds across all three domains. Higher tiers require stronger fundamentals and active participation in the standard.

- Overall score of 60 or above
- No critical failures in any domain
- Passing marks in Agent Safety
Your site is actively signaling AI agent compatibility and meets strong standards.
- Overall score of 75 or above
- agents.json published and valid
- No critical failures in any domain
- Bronze requirements met
Your site exemplifies best-in-class AI agent readiness. The highest Foundry Standard certification.
- Overall score of 90 or above
- Annual certification audit
