# AX Check: allbirds.com Checked 2026-10-21. Agent guide is solid, but the MCP shopping link is broken llms.txt gives clear discovery-to-checkout steps and plain retail prices ($75-$105), but the advertised MCP endpoint returns a 404 instead of connecting. ## End-to-end onboarding not demonstrated ## Coding sessions All three independent sessions completed and read the site as a retail storefront with no API pricing tier. None could state a cost figure or pricing assumptions: one cited retail shoe prices with no source, the other two simply reported that no developer pricing exists. ### DeepSeek V4.1 Flash [View public run](https://agents.withgauge.com/p/runs/c31094de-f961-46d2-9666-87614ec14ccc) · [Read transcript](https://www.ax-check.com/allbirds.com/sessions/deepseek.json) Said only that pricing is per-item retail with no API tier. Gave no cost figure and named no plan, workload or other assumption behind one (seq 18) #### End-to-end onboarding - **End-to-end onboarding not demonstrated**: The agent never found any developer platform, API, SDK, or credential issuance mechanism for Allbirds. It only confirmed Allbirds is a retail storefront with no public developer surface, so no credentials were obtained and no authenticated operation was ever attempted. Event 16: ```text local_rate_limited=== search check === allbirds developer api sdk allbirds developer api sdk ``` Event 18: ```text There is no developer workflow to act on — no SDK, API, keys, or hosted sandbox. ``` #### Hallucinated URLs None identified in this transcript. #### Blockers - **Allbirds has no public developer platform**: Product behavior/reality: Allbirds is a consumer retail brand, not a developer product. DNS lookups for plausible developer subdomains all failed to resolve, and the main site only returned a rate-limit response, confirming there is no API, SDK, or docs surface to build against. Event 15: ```text developer.allbirds.com -> NXDOMAIN developers.allbirds.com -> NXDOMAIN docs.allbirds.com -> NXDOMAIN api.allbirds.com -> NXDOMAIN ``` Event 10: ```text 429 --- curl: (6) Could not resolve host: api.allbirds.com ``` #### Suggested Changes None identified in this transcript. ### Kimi K3 [View public run](https://agents.withgauge.com/p/runs/19b26c64-5cbf-410c-b9cf-5acd5b3bc655) · [Read transcript](https://www.ax-check.com/allbirds.com/sessions/kimi.json) The agent quoted shoe prices of about $95–$140 with no source, model or region named. It also said no API pricing exists, but it checked nothing to support that. (seq 2) #### End-to-end onboarding - **End-to-end onboarding not demonstrated**: No onboarding was attempted. The agent determined immediately that Allbirds is a consumer footwear/apparel retailer with no public SDK, API, or developer surface, and stopped per the user's explicit instruction to do so if no developer workflow exists. Event 2: ```text it has no developer product, no public SDK, no API, and no hosted service a developer could build against. There's no developer workflow here I can act on. ``` #### Hallucinated URLs None identified in this transcript. #### Blockers - **No developer product exists for Allbirds**: Product behavior / fundamental mismatch, not an agent error or missing credentials: Allbirds is a retail footwear and apparel brand with no REST API, SDK, webhooks, or sandbox environment. The agent correctly recognized this and halted rather than fabricating an integration. Event 2: ```text There's no developer workflow here I can act on. ``` Event 2: ```text Not possible. There's nothing to integrate with — no REST API, no SDK, no webhooks, no sandbox. The only interfaces are a consumer retail website and physical stores. ``` #### Suggested Changes None identified in this transcript. ### Qwen 3.8 Max [View public run](https://agents.withgauge.com/p/runs/9ed22e86-e5ef-478b-bb90-a956f5ac5f66) · [Read transcript](https://www.ax-check.com/allbirds.com/sessions/qwen.json) The agent gave no cost figure and no assumptions. It only said there is no developer pricing and that Allbirds pricing is just retail shoe prices. (seq 6) #### End-to-end onboarding - **End-to-end onboarding not demonstrated**: The agent never attempted to obtain credentials or call any API. It inspected an empty local repo and then concluded Allbirds has no public SDK/API, stopping per the prompt's own instruction to say so plainly if no developer workflow exists. Event 6: ```text Allbirds has no developer workflow I can act on. ``` Event 4: ```text total 16 drwxr-xr-x 3 root root 4096 Sep 18 08:00 . drwxr-xr-x 8 root root 4096 Sep 24 20:05 .git -rw-r--r-- 1 root root 408 Sep 18 08:00 .gitignore ``` #### Hallucinated URLs None identified in this transcript. #### Blockers - **Allbirds has no public SDK or API to build against**: This is product reality, not agent error or a test-environment limitation: Allbirds is a retail footwear brand running on Shopify with no documented developer platform, SDK, or partner API. The agent correctly identified this after checking the local repo for any hints and finding none, then halted as instructed rather than inventing an integration. Event 6: ```text There is: - **No SDK or public API** — no official Allbirds SDK, REST API, or developer docs to build against. They're a Shopify-based e-commerce store, and they don't offer a public developer platform or partner API. ``` #### Suggested Changes None identified in this transcript. ### Task given to each agent Help me build a simple example using Allbirds. Tell me how pricing works, and briefly tell me whether this product will be easy for you to manage. Let me know if you get blocked. If this product has no developer workflow you can act on, say so plainly and stop. Stay light: use the hosted product through its SDK or API. Do not start local service stacks or wait for long-running commands; if the quickstart requires either, say so plainly and stop. No product credentials were supplied and no purchases were authorized. ## Score: B · 67/100 (provisional) Grades come from completed site checks. Coding sessions and skipped checks do not affect the score. ### Clarity - **Failed** — Homepage answers Markdown requests ```text Homepage returned text/html even when text/markdown was requested; no Markdown representation offered. ``` - **Failed** — Install and next-step links resolve ```text llms.txt advertises MCP endpoint https://www.allbirds.com/api/ucp/mcp, but that fetch returned 404. ``` - **Pass** — llms.txt provides an actionable documentation index ```text llms.txt links Shop skill, UCP profile, MCP endpoint, WebMCP docs, sitemap and policies. ``` - **Pass** — llms.txt provides navigation guidance ```text llms.txt gives ordered steps: discover UCP profile, list MCP tools, then shop. ``` - **Pass** — llms.txt mentions offered API, MCP, and skills ```text llms.txt names the Shop skill, UCP MCP endpoint, and WebMCP tools. ``` - **Pass** — A compact guide representation exists ```text Allbirds /llms.txt is a compact Markdown agent guide covering Shop skill and UCP integration. ``` - **Pass** — A focused guide is directly retrievable ```text /llms.txt directly retrievable as text/markdown with concrete discovery, MCP and checkout steps. ``` - **Pass** — Equivalent instructions fit a token budget ```text llms.txt is 1203 tokens, well under the 8000-token budget. ``` - **Skipped** — Product-docs links survive format changes ```text Homepage Markdown unsupported, so link preservation across formats cannot be measured. ``` - **Pass** — The compact guide is independently actionable ```text Allbirds llms.txt gives actionable agent shopping steps: UCP discovery, MCP tools, WebMCP checkout, buyer authorization. ``` ### Onboarding - **Pass** — Docs lead to a relevant quickstart ```text Allbirds llms.txt links the Shop skill and UCP integration with a step-by-step discovery-to-checkout flow. ``` - **Pass** — Installation commands are extractable ```text llms.txt gives concrete commands: GET /.well-known/ucp, connect MCP endpoint, use tools/list. ``` - **Pass** — Code examples are available without interaction ```text llms.txt documents UCP endpoints and tool calls inline without requiring interaction. ``` - **Pass** — Prerequisites and auth boundaries are explicit ```text llms.txt states buyer authorization, agent identification via Web Bot Auth, and rate-limit handling. ``` ### Pricing - **Failed** — Agents identify pricing and its assumptions ```text 3 of 3 sessions were judged on pricing; 3 fell short. DeepSeek V4.1 Flash: Said only that pricing is per-item retail with no API tier. Gave no cost figure and named no plan, workload or other assumption behind one (seq 18) Kimi K3: The agent quoted shoe prices of about $95–$140 with no source, model or region named. It also said no API pricing exists, but it checked nothing to support that. (seq 2) Qwen 3.8 Max: The agent gave no cost figure and no assumptions.
