Method

How a site gets a grade.

AgentBoard crawls public URLs the way an agent would: well-known files, OpenAPI, MCP metadata, pricing objects. No login. No JavaScript execution. Rank on the board is this score. Money cannot buy a higher grade.

• A · 80–100   B · 60–79   C · 40–59   D · 20–39   F · 0–19
• Verified badge is automatic at 60+. Not for sale.
• Featured is a 7-day pin for sites already at 25+. It does not change the score.
• Max score is 100. Partial credit is allowed on most checks.
