Example use cases
Audit competitor AI discoverability

Verify partner site llms.txt
“We're onboarding a new API partner and I want to make sure their site is AI agent friendly — can you check whether stripe.com has an llms.txt deployed and share the contents along with any recommendations?”
Bulk vendor AI readiness check
“I'm evaluating a few SaaS vendors for our procurement list. Can you start by checking whether salesforce.com has an llms.txt or llms-full.txt file and let me know if they should deploy one?”

Endpoint
GEThttps://nexus-agent-xa12.onrender.com/util/llms-auditWhen to prefer
Use this endpoint when you need to programmatically check whether a specific company website has adopted the llms.txt standard for AI agent discoverability. Prefer this over manual inspection or generic web scrapers when you want a structured response with deployment recommendations and full content retrieval in one call.
