## What the machine actually did
The agent got through 10 of 15 requests, but could not find a contact route for machines. It came up empty on 4 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
- missing 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 MCP manifest was found at the 3 standard paths checked, so an agent has no published machine door to this site.** (agent_aware_instrumentation)
2. **No security.txt is published, so a machine has no documented route to report a problem.** (machine_fetchable_trust)
3. **No OpenAPI specification is published, requiring agents to write API clients by hand from prose documentation.** (programmatic_onboarding)
The evidence and the recommended fix for each are on the report page: https://www.seconddoor.io/r/rankscale-tdthx9
## Files generated from this scan
- **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/rankscale-tdthx9
## The agent door
- **machine_discoverability** 100/100. Robots.txt names 10 AI crawlers and allows them all. A real browser is served the page normally. No user agent rule refuses declared crawler names.
- **programmatic_onboarding** 18/100. Authentication is documented at /api in prose form. No OpenAPI spec exists at any of 6 standard paths. No self-serve API key issuance is published.
- **pricing_legibility** 93/100. 8 prices are readable without JavaScript on the pricing page. No tier is gated behind a sales contact. Plans are published as Offer structured data. Prices range from $20 to $780 per month.
- **agent_aware_instrumentation** 20/100. Robots.txt names 10 AI crawlers and allows them. No MCP manifest is published at any of 3 standard paths. No ai-plugin.json exists. No Web Bot Auth signals are present.
- **machine_fetchable_trust** 40/100. No security.txt is published at /.well-known/security.txt. The homepage answers automated requests. No trust signals are machine readable. A visitor cannot verify the site's security posture or contact information without reading HTML.
- **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. The site answered our automated browser with a traffic challenge, so the form itself could not be read. A human following the same link reaches the form. Nothing behind the wall was measured.
- **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.
