How this service works
Agent-readiness check for a public site: robots.txt AI-bot rules, llms.txt, JSON-LD schema, OpenAPI/MCP discovery, /.well-known/x402. Deterministic 0-100 score + fixes. Max 6 capped public GETs. Bad url → 400, unreachable host → 422, both charged:false (checked before settle).
Output
A JSON object with an overall 0–100 agent-readiness score, per-check results (robots.txt AI-bot rules, llms.txt presence, JSON-LD schema, OpenAPI/MCP endpoint discovery, /.well-known/x402), a list of concrete fix recommendations, and any errors encountered. The `charged` field indicates whether the call was billed.
Example use cases
Pre-launch AI readiness audit
“Before I launch my new SaaS site at myapp.io, can you check its agent-readiness score and list everything I need to add — like llms.txt, robots.txt AI rules, and x402 support?”
Competitor agent-discoverability check
“How agent-ready is my competitor's site at acme.com? Give me the score and highlight any gaps compared to what a well-configured AI-accessible site should have.”
Developer compliance verification
“I just added an llms.txt and OpenAPI spec to devtools.example.com — can you re-run the agent-readiness check and confirm those signals are now being detected correctly?”
Technical details
Endpoint
POSThttps://x402-v2-mint-agent-readiness.vercel.app/v1/agent-readiness?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, deterministic, standards-based audit of a public website's AI-agent compatibility — specifically checking robots.txt bot permissions, llms.txt, JSON-LD structured data, OpenAPI/MCP discovery endpoints, and x402 payment support. Prefer it over general SEO or crawlability tools when the goal is AI-agent discoverability and interoperability rather than search engine ranking.
Side effects
- Bad or malformed URL returns HTTP 400 with charged:false
- Unreachable or non-existent host returns HTTP 422 with charged:false
- Rate limit: capped at 6 public GETs per call to avoid abuse
- Timeout if target site is extremely slow to respond
- Private or localhost URLs likely rejected as non-public
