# Function Health: 15 point Door Gap
- Site: functionhealth.com

- Scanner version: 12
AI agents cannot discover or access the API, and the network edge blocks crawlers that robots.txt welcomes.
## Scores
| Measure | Score |
| --- | --- |
| Humans | 58/100 |
| Agents | 43/100 |
| Composite | 51/100 |
| Door Gap | 15 points |
| Percentile | 16th |
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 6 of 15 requests, but could not ask whether the door opens for requests carrying the AI crawlers' names. It came up empty on 8 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
- ok      read the prices without running JavaScript
- missing find a comparison page worth citing
- ok      walk the way a visitor would, to a signup form or a product
## Top issues
1. **The network edge refuses 2 declared AI crawlers that robots.txt welcomes, so the published policy and the actual behaviour disagree.** (machine_discoverability)
2. **No developer documentation is linked from the homepage, in raw HTML or the rendered page, so integration starts with a search engine.** (programmatic_onboarding)
3. **robots.txt blocks 7 AI crawlers, so those assistants cannot read this site at all.** (machine_discoverability)
The evidence and the recommended fix for each are on the report page: https://www.seconddoor.io/r/functionhealth-ndmhqy
## 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.
- **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.
- **A comparison page brief** at `/compare/function-health-vs-competitor`, 3 hours, no developer needed. Verify: The next scan finds a comparison page listed in the sitemap or linked from the homepage, and reads its text without JavaScript.
- **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.
- **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/functionhealth-ndmhqy
## The agent door
- **machine_discoverability** 57/100. Robots.txt blocks 7 training crawlers (gptbot, claudebot, google-extended, ccbot, applebot-extended, meta-externalagent, bytespider) while welcoming search and agent crawlers.
- **programmatic_onboarding** 10/100. No API documentation is linked from the homepage. No OpenAPI spec exists at any of the 6 standard paths checked. No MCP manifest, OAuth metadata, or pricing.md is published.
- **pricing_legibility** 85/100. 10 prices are readable in raw HTML without JavaScript, ranging from $1 to $15,000. No tier is gated behind a sales contact or demo request. Prices are published on the pricing page with clear per-month or per-seat terms.
- **agent_aware_instrumentation** 0/100. No MCP manifest is published at any of the 3 standard paths. Robots.txt blocks 7 AI crawlers by name, including gptbot and claudebot. No ai-plugin.json or llms.txt is present.
- **machine_fetchable_trust** 40/100. No security.txt is published at /.well-known/security.txt. The homepage answers automated requests and publishes an Organization schema with a ContactPoint.
- **commercial_rails** 65/100. Prices are published in raw HTML on the pricing page. A self-serve signup form is reachable from the homepage in 2 steps and asks for 11 fields, 5 required, with no payment card requested. The form does not gate access to a trial.
## The human door
- **steps_to_first_value** 80/100. The primary call to action, 'Start testing', is 2 steps from the homepage and leads to a signup form. The form does not require payment or email verification before submission.
- **required_fields** 45/100. The signup form has 11 fields total. 5 are required: Email, First name, Last name, Phone number, and Date of birth. The remaining 6 are optional. A visitor must provide personal information to proceed, but the form does not demand company.
- **verification_walls** 65/100. No verification requirement is visible on the signup page itself. The form does not display copy about email confirmation, phone verification, or identity checks before submission.
- **error_recovery** 43/100. 2 of 12 form inputs carry validation rules. The form includes 2 live regions for error messaging. No inline error containers are present on the page.
