# Dualmark Playground

> Free AI agent readiness check. Score any URL against the AEO Spec v1.0.

Paste any URL into https://dualmark.dev/play and get back a 0-125 conformance score in under 200ms. Tells you exactly which AEO checks pass and fail, with the exact response details.

## Use the API directly

```bash
curl -X POST https://dualmark.dev/api/play/score \
  -H "Content-Type: application/json" \
  -d '{"url":"https://yoursite.com/your-page"}'
```

Returns a JSON `VerifyReport` with score, level (Below Basic / Basic / Standard / Advanced), passed checks, and failed checks.

## Or use the CLI locally

```bash
bunx @dualmark/cli verify https://yoursite.com/your-page
```

Same engine, same checks, exits non-zero on failure. Drop into CI to fail builds when conformance drops.

## What's checked

13 checks across markdown twin reachability, headers, body content, HTML link advertising, and HTTP content negotiation. See https://dualmark.dev/docs/conformance/scoring for the full breakdown and weights.
