Agent door only. The human door could not be measured on this scan. A Door Gap needs both doors, so this scan does not report one.
## What the machine actually did
The agent got through 4 of 12 requests, but could not ask whether the door opens for requests carrying the AI crawlers' names. It came up empty on 7 other checks too. That is enough missing for a machine to give up before it reaches a purchase.
- ok      reach the site at all
- ok      find out whether machines are welcome
- missing 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
- 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
- missing find a machine readable API spec
- missing read the developer documentation
## Top issues
1. **The network edge refuses 5 declared AI crawlers that robots.txt welcomes, so the published policy and the actual behaviour disagree.** (machine_discoverability)
2. **No machine-readable trust or integration signals are published, leaving agents with no way to verify the site's security posture or discover supported integrations.** (machine_fetchable_trust)
3. **No API documentation or OpenAPI specification is published, leaving no programmatic entry point for agents to discover or integrate with the site.** (programmatic_onboarding)
The evidence and the recommended fix for each are on the report page: https://www.seconddoor.io/r/churnzero-wn9pm4
## Files generated from this scan
- **Let verified assistants through** at `notes`, 1 hour, developer. Verify: The next scan opens the homepage and the key pages in a real browser and under the search crawler names, and every one is served.
- **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.
- **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.
- **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.
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/churnzero-wn9pm4
## The agent door
- **machine_discoverability** 75/100. Robots.txt names Claudebot and allows 14 AI crawlers by role, and a sitemap declares 416 URLs. The homepage renders 2000 characters to a real browser.
- **programmatic_onboarding** 10/100. No API documentation is linked from the homepage, and no OpenAPI spec exists at any of the 6 standard paths checked. The site publishes no programmatic entry point for agents to discover or use.
- **pricing_legibility** null/100. Could not verify: this scan did not reach the pages that would show it.
- **agent_aware_instrumentation** 20/100. Robots.txt names Claudebot explicitly and allows 14 AI crawlers by role, showing awareness of agent traffic. No MCP manifest exists at the standard path checked. No ai-plugin.json or llms.txt file is published.
- **machine_fetchable_trust** 40/100. The homepage answers automated requests with HTTP 200 and structured data (11 schema.org types including Organization). No security.txt file is published at the standard path. No Web Bot Auth signals are present.
- **commercial_rails** 10/100. The site is classified as a content publisher with subscription wording but no cart. No payment or transaction infrastructure is visible in the homepage content, structured data, or API surface.
## The human door
- **steps_to_first_value** null/100. Could not verify: this scan did not reach the pages that would show it.
- **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.
