C
Why this grade
A middle-of-the-pack C. Credit on robots.txt AI-agent rules, but the biggest gaps are on Public MCP registry listing and SDK availability across languages — closing those would lift this toward a B.

Low-cost fixes that would nudge this grade up.
- /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).

- /.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.

Findings (33)
Anti Bot · 2
| Check | Status | Points | Notes |
|---|---|---|---|
| Anti-bot interstitial | pass | 10 / 10 | No anti-bot interstitial markers on a single polite homepage request — behavioural anti-bot can still challenge real crawler traffic. |

Api · 3
| Check | Status | Points | Notes |
|---|---|---|---|
| GraphQL introspection | skip | — | No GraphQL endpoint found at any of 3 conventional paths. |
| JSON error bodies for API callers | pass | 5 / 5 | HTTP 404 with parseable JSON body (Content-Type: application/json). |
| OpenAPI specification discovery | pass | 10 / 10 | OpenAPI 3.1.0 served at /openapi.json (19 paths, 3 schemas). |
Crawl · 3
| Check | Status | Points | Notes |
|---|---|---|---|
| RSS/Atom feed | skip | — | No RSS/Atom feed found at probed paths or via `<link rel="alternate">`. |

Docs · 2
| Check | Status | Points | Notes |
|---|---|---|---|
| Docs platform discoverability | warn | 3 / 6 | Docs found at /developers but platform is custom — crawler-friendliness is unknown. |
| SDK availability across languages | fail | 0 / 8 | No SDKs discoverable via npm, PyPI, or the docs page. |
Html Meta · 3
| Check | Status | Points | Notes |
|---|---|---|---|
| JSON-LD structured data | pass | 4 / 8 | JSON-LD present (WebSite); missing a machine-targeted `@type: WebAPI`/`SoftwareApplication` for full credit. |
| meta description | info | — | Meta description present (119 characters) (informational — not graded). |
| Open Graph tags | info | — | All three core Open Graph tags present on the homepage (informational — not graded). |
Identity · 3
| Check | Status | Points | Notes |
|---|---|---|---|
| Email auth (SPF, DMARC, DKIM) | info | — | No SPF / DMARC / DKIM found — domain has no email auth (informational — email trust, not agent discoverability). |
| security.txt responsible-disclosure declaration | skip | — | No security.txt found at either probed path — secondary signal, not a negative one. |
| TLS + HSTS + HTTPS redirect | warn | 5 / 10 | Cert valid, but `http://` did not redirect to `https://`. (HSTS max-age=31536000 — informational.) |
Llm Training · 3
| Check | Status | Points | Notes |
|---|---|---|---|
| Common Crawl index presence | skip | — | Common Crawl CDX endpoint was unreachable — not penalising target. |

| Wikipedia article | info | — | 1 Wikipedia article(s) match "ainglish" (Aron Wieder) but none link to ainglish.org — a name match without a domain link is not attribution (informational — not graded). |
Onboarding · 1
| Check | Status | Points | Notes |
|---|---|---|---|
| API-key / signup path discoverability | warn | 3 / 6 | Signup/API-key page found at /register but nothing on the homepage or docs links to it — a crawler would have to guess. |
Protocols · 2

| Public MCP registry listing | fail | 0 / 10 | Host ainglish.org not listed in any of 2 registry/registries consulted. |
