D
Why this grade
A D grade. What you have on robots.txt AI-agent rules is being outweighed by missing signals on Anti-bot interstitial and JSON-LD structured data. Fix those first for the biggest score lift.

Quick wins
Low-cost fixes that would nudge this grade up.
- JSON error bodies for API callers Return a JSON error body (application/json or application/problem+json), not an HTML page, when the caller sends `Accept: application/json`.
- /ai.txt AI-crawler directives Add a short `/ai.txt` at the site root declaring your AI-crawler usage terms (see spawning.ai/ai-txt).
- /llms-full.txt long-form index Add a `/llms-full.txt` — the full-text companion to llms.txt with your key docs inlined for LLMs (see llmstxt.org).
- /.well-known/agent.json (A2A AgentCard) Publish an A2A AgentCard at `/.well-known/agent.json` with name, description, skills, and endpoints.
- /.well-known/ai-plugin.json manifest Publish a `/.well-known/ai-plugin.json` manifest with name_for_model, description_for_model, and an api block.
Blocking issues
High-weight checks that aren't passing.
- Anti-bot interstitial Anti-bot interstitial detected via body marker `cdn-cgi/challenge-platform`. LLM crawlers hitting this see nothing.
