## Scores
| Measure | Score |
| --- | --- |
| Humans | 80/100 |
| Agents | 59/100 |
| Composite | 70/100 |

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 11 of 15 requests, but could not find a contact route for machines. It came up empty on 3 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
- ok      read the site's own guide for language models
- ok      find out what pages exist
- missing 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
- ok      read the homepage as data rather than as a page
- ok      find a machine readable API spec
- ok      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 security.txt is published, leaving no machine readable contact point for security issues or agent integration questions.** (machine_fetchable_trust)
2. **Signup page blocks automated browsers with a traffic challenge, preventing agents from obtaining API credentials without human intervention.** (programmatic_onboarding)
3. **No MCP manifest is published at any of the 3 standard paths, preventing agents from discovering integration capabilities without reading documentation.** (agent_aware_instrumentation)

## Files generated from this scan
- **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.
- **security.txt** at `/.well-known/security.txt`, 10 minutes, no developer needed. Verify: The next scan fetches /.well-known/security.txt as text and the security.txt check passes.
Each file is written from what this scan found on the site. The content is in the JSON once the evidence is opened: https://www.seconddoor.io/api/reports/close-9apk6m
## The agent door
- **machine_discoverability** 100/100. No AI crawler is blocked by robots.txt, a real browser is served the page normally, key pages render without JavaScript, a sitemap lists 1382 URLs, 6 schema.org types appear on the homepage, comparison pages are listed and readable without.
- **programmatic_onboarding** 50/100. A machine readable OpenAPI spec is published at developer.close.com/openapi.json, but the signup page is protected by automated traffic detection that blocks browser automation, preventing agents from obtaining API credentials without.
- **pricing_legibility** 96/100. 33 prices are readable without JavaScript on the pricing page, with plans named Solo/Essentials, Growth, and Scale at $9, $35, $99, and $139 per seat. An enterprise tier routes to sales, which is standard practice.
- **agent_aware_instrumentation** 28/100. A machine readable API spec is published, but no MCP manifest exists at the 3 standard paths checked, and no ai-plugin.json is published. OAuth authorization metadata and pricing.md are also absent, limiting machine-driven integration.
- **machine_fetchable_trust** 40/100. No security.txt is published at /.well-known/security.txt, and the homepage answers automated requests without a trust signal. The site does allow declared AI crawlers by user agent, but provides no machine readable security or contact.
- **commercial_rails** 40/100. Prices are published in raw HTML, the plans are published as Offer structured data.
## The human door
- **steps_to_first_value** 80/100. The signup page is 2 steps from the homepage via the Try for free call to action. The site answered the automated browser with a traffic challenge, so the form itself could not be read.
- **required_fields** null/100. Could not verify: this scan did not reach the pages that would show it.
- **verification_walls** null/100. Could not verify: this scan did not reach the pages that would show it.
- **error_recovery** null/100. Could not verify: this scan did not reach the pages that would show it.
