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 8 of 17 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 read the product catalogue as data
- ok      read a product page as data
- ok      read the returns and shipping terms
- ok      walk the way a visitor would, to a signup form or a product
## Top issues
1. **The network edge refuses 3 declared AI crawlers that robots.txt welcomes, so the published policy and the actual behaviour disagree.** (machine_discoverability)
2. **No OpenAPI specification was found at the 6 standard paths checked, so a client must be written from prose instead of generated.** (programmatic_onboarding)
3. **No developer documentation is linked from the homepage, in raw HTML or the rendered page, so integration starts with a search engine.** (programmatic_onboarding)
The evidence and the recommended fix for each are on the report page: https://www.seconddoor.io/r/nike-zj422c
## 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.
- **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.
- **Agent checkout: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds a UCP manifest, a storefront MCP endpoint or another discovery file answering, and the checkout 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.
- **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.
- **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/nike-zj422c
## The agent door
- **machine_discoverability** 75/100. Nike publishes a sitemap with 113 URLs and serves structured data (5 schema.org types) on the homepage to all automated clients. However, the network edge refuses requests from gptbot, perplexitybot and oai-searchbot despite robots.txt.
- **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. Nike offers no programmatic route for agents to browse or purchase products.
- **pricing_legibility** 35/100. Eight prices appear in the homepage HTML, but no product pages could be reached to measure structured pricing data. The homepage shows prices for promotional items, but the full catalogue pricing remains unmeasured because product links.
- **agent_aware_instrumentation** 8/100. No MCP manifest exists at any of the 3 standard paths checked. Nike has not published machine-readable instructions for how agents should interact with the site.
- **machine_fetchable_trust** 65/100. The returns policy and shipping policy both read as plain text at their published URLs and are accessible to automated clients. However, neither policy is embedded in structured data on product pages, and no security.txt file is published.
- **commercial_rails** null/100. Could not verify: this scan did not reach the pages that would show it.
## 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.
