| Measure | Score |
| --- | --- |
| Humans | 77/100 |
| Agents | 58/100 |
| Composite | 68/100 |
| Door Gap | 19 points |

The human score is the mean of the four human dimensions, the agent score the mean of the six agent dimensions, and the Door Gap the difference between them.
## What the machine actually did
The agent got through 8 of 15 requests, but could not read the site's own guide for language models. It came up empty on 6 other checks too.
- ok      reach the site at all
- ok      find out whether machines are welcome
- ok      ask whether the door opens for requests carrying the AI crawlers' names
- missing read the site's own guide for language models
- ok      find out what pages exist
- ok      find a contact route for machines
- missing find a published agent interface
- missing find an agent plugin manifest
- missing find out whether verified agents are recognised
- missing read the homepage as data rather than as a page
- missing find a machine readable API spec
- missing read the developer documentation
- ok      read the prices without running JavaScript
- ok      find a comparison page worth citing
- ok      walk the way a visitor would, to a signup form or a product
## Top issues
1. **No developer documentation is linked from the homepage, in raw HTML or the rendered page, so integration starts with a search engine.** (programmatic_onboarding)
2. **API documentation contains no credentials, endpoints, code samples or authentication details.** (programmatic_onboarding)
3. **No machine-readable integration signals are published for AI agents or tools.** (agent_aware_instrumentation)

## Files generated from this scan
- **Pricing as Offer structured data** at `pricing page`, 20 minutes, developer. Verify: The next scan reads Offer structured data with a price and currency on the pricing page, and the pricing check credits it.
- **robots.txt rules for AI crawlers** at `/robots.txt`, 10 minutes, no developer needed. Verify: The next scan reads robots.txt and finds every search and agent crawler allowed, none of them kept off product or pricing paths.
- **Machine interfaces: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds the interface you published answering at its well-known path, and that check passes.
- **pricing.md** at `/pricing.md`, 20 minutes, no developer needed. Verify: The next scan fetches /pricing.md as text and records pricing as machine readable.
- **Organization structured data** at `homepage`, 15 minutes, developer. Verify: The next scan reads Organization and WebSite nodes in the homepage JSON-LD and the structured data check passes.
- **llms.txt** at `/llms.txt`, 15 minutes, no developer needed. Verify: The next scan fetches /llms.txt as text and the llms.txt check passes.

## The agent door
- **machine_discoverability** 94/100. No AI crawler is blocked by robots.txt, a real browser is served the page normally, and key pages including pricing and docs are readable without JavaScript.
- **programmatic_onboarding** 10/100. The documentation at /docs and /docs/developers contains 86051 characters of text but shows no API credentials, endpoints, code samples, authentication documentation, or self-serve key issuance.
- **pricing_legibility** 85/100. Three prices are readable without JavaScript on the pricing page: $14, $24, and $36 per seat per month. An enterprise tier routes to sales, which is standard practice. Currency and billing model are clear.
- **agent_aware_instrumentation** 8/100. No MCP manifest is published at any of the three standard paths checked. No ai-plugin.json or llms.txt is present. The site does not signal machine-readable integration points.
- **machine_fetchable_trust** 85/100. security.txt is published at /.well-known/security.txt with a contact route for machines. The homepage responds to automated requests with HTTP 200 and serves content normally to a browser carrying an AI crawler user agent.
- **commercial_rails** 65/100. Prices are published in raw HTML, a self serve signup form is reachable from the homepage.
## The human door
- **steps_to_first_value** 80/100. The primary call to action, 'Try for Free', is 2 steps from the homepage and leads to a signup form. The form itself is 2 steps from the homepage. No account system is required to view pricing or documentation.
- **required_fields** 98/100. The signup form contains 3 fields, 0 of which are required. Two sign-in options are offered: Google and Apple. A visitor can proceed without entering any data.
- **verification_walls** 80/100. No verification requirement appears on the signup page. Single sign-on via Google or Apple avoids email verification entirely. The form does not ask for phone, address, or payment details.
- **error_recovery** 50/100. The page has 4 inline error containers, but 0 of the 3 inputs carry validation rules or descriptions. A visitor will not know what format is expected before submission.
