# AX Check: pandas.pydata.org Checked 2026-09-18. Install and quickstart work fine; no Markdown docs for agents. Install commands and getting-started tutorials resolve cleanly (8 of 23 checks pass), but no llms.txt or Markdown guide exists to help agents navigate docs quickly. ## End-to-end onboarding not demonstrated ## Coding sessions All three independent sessions (DeepSeek V4 Pro, Kimi K3, Qwen 3.8 Max) completed and correctly identified pandas as free, open-source (BSD-3-Clause) software with no tiers, usage fees, or API keys required, only local compute cost. ### DeepSeek V4 Pro [View public run](https://agents.withgauge.com/p/runs/ebe5b7d6-c51a-446b-b0bd-1e822b042dce) · [Read transcript](https://www.ax-check.com/pandas.pydata.org/sessions/deepseek.json) Seq 13 states the price ('Free... BSD-3-Clause, no usage fees, no tiers, no credit card') with the explicit basis that pandas is a self-hosted open-source library rather than a metered/hosted service. #### End-to-end onboarding - **End-to-end onboarding not demonstrated**: Pandas is a local open-source library with no hosted product, SDK, API, or credentials. The agent correctly identified this and never attempted authentication or a hosted operation — there was nothing to onboard to. Event 13: ```text pandas has **no hosted product, SDK, or API**, so there's no remote developer workflow to act on. The only workflow is local Python. ``` #### Hallucinated URLs None identified in this transcript. #### Blockers None identified in this transcript. #### Suggested Changes None identified in this transcript. ### Kimi K3 [View public run](https://agents.withgauge.com/p/runs/d439b0e7-1d25-456a-9446-07b844d8be68) · [Read transcript](https://www.ax-check.com/pandas.pydata.org/sessions/kimi.json) Final output states cost is $0 with explicit basis: BSD-3-Clause open-source license, no tiers/usage limits/API keys, only cost is local compute (seq 14). #### End-to-end onboarding - **End-to-end onboarding not demonstrated**: Pandas is an open-source local Python library with no hosted service, accounts, credentials, or API. The agent recognized this immediately and never attempted or needed any onboarding, credential fetch, or authenticated operation, correctly stopping per instructions since there is no developer workflow to act on. Event 6: ```text pandas isn't a hosted product** — it's a free, open-source Python library (BSD-3-Clause license). There's no pricing, no API keys, no accounts, and no SDK-to-cloud workflow. ``` #### Hallucinated URLs None identified in this transcript. #### Blockers None identified in this transcript. #### Suggested Changes None identified in this transcript. ### Qwen 3.8 Max [View public run](https://agents.withgauge.com/p/runs/7e5e605d-27e9-4b57-9a4a-75198bc1edf1) · [Read transcript](https://www.ax-check.com/pandas.pydata.org/sessions/qwen.json) Final output states pandas is free/OSS (BSD 3-Clause, NumFOCUS-maintained) with the explicit basis 'no hosted tier, no API key, no metered usage' as the assumption behind the zero-cost figure. #### End-to-end onboarding - **End-to-end onboarding not demonstrated**: No product credentials were obtained or used. Pandas is a local open-source library with no hosted API, account, or auth surface, so there was no self-service credential acquisition or authenticated hosted operation to verify. The agent correctly identified this and did not attempt to fabricate a workflow. Event 13: ```text cd /sandbox/repo && python3 pandas_example.py ``` Event 16: ```text pandas isn't a hosted product and has no such SDK/API, so I used it the only way it exists: as an installed Python library. ``` #### Hallucinated URLs None identified in this transcript. #### Blockers - **No hosted product or developer workflow exists to test**: The seed prompt asked for use of a hosted product's SDK/API and pricing info, but pandas is a free local library with no hosted tier, API key, or SDK. This is a product-category mismatch rather than a defect in any product — the agent flagged it plainly instead of inventing a hosted workflow. Event 16: ```text pandas has no pricing — it's free, open-source software under the BSD 3-Clause license, maintained by a nonprofit (NumFOCUS). There's no hosted tier, no API key, no metered usage. ``` Event 16: ```text pandas isn't a hosted product and has no such SDK/API, so I used it the only way it exists: as an installed Python library. ``` #### Suggested Changes None identified in this transcript. ### Task given to each agent Help me build a simple example using pandas. 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: C · 50/100 (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 despite text/markdown Accept header; no Markdown representation offered. ``` - **Failed** — llms.txt provides an actionable documentation index ```text /llms.txt returns HTTP 404 on GitHub Pages; no documentation index exists. ``` - **Skipped** — llms.txt provides navigation guidance ```text No llms.txt body was returned (404), so navigation guidance cannot be judged. ``` - **Skipped** — llms.txt mentions offered API, MCP, and skills ```text No llms.txt body was returned (404), so API/MCP/skills mentions cannot be judged. ``` - **Skipped** — A compact guide representation exists ```text No site-published Markdown guide; homepage negotiation returned HTML, and /llms.txt is 404. ``` - **Skipped** — A focused guide is directly retrievable ```text No standalone .md or negotiated Markdown guide was fetched; only HTML docs pages. ``` - **Skipped** — Equivalent instructions fit a token budget ```text No Markdown compact guide exists to measure against the token budget. ``` - **Skipped** — Product-docs links survive format changes ```text Homepage Markdown unsupported, so link preservation across formats cannot be judged. ``` - **Pass** — The compact guide is independently actionable ```text Getting started page gives concrete install commands (conda/pip) and tutorial first steps. ``` - **Pass** — Install and next-step links resolve ```text Install and next-step links resolve: getting_started, install, tutorials, API reference all fetched 200. ``` ### Onboarding - **Pass** — Docs lead to a relevant quickstart ```text Getting started page links 10 intro tutorials and 10 Minutes to pandas quickstart. ``` - **Pass** — Installation commands are extractable ```text Install page gives extractable commands: conda install -c conda-forge pandas and pip install pandas. ``` - **Pass** — Code examples are available without interaction ```text Install and getting-started pages show inline code examples without requiring interaction. ``` - **Pass** — Prerequisites and auth boundaries are explicit ```text Install page lists required dependencies and Python version support; no auth needed for a library. ``` ### Pricing - **Skipped** — Pricing is readable without interaction ```text Not applicable: the relevant product is free. pandas is a free open source library; no pricing page or paid plans exist. ``` - **Skipped** — Prices are stated, not gated ```text Not applicable: the relevant product is free. No prices are stated because pandas is free open source software. ``` - **Skipped** — Pricing units and limits are explicit ```text Not applicable: the relevant product is free. No pricing units or limits apply; pandas is free open source software. ``` - **Skipped** — Agents identify pricing and its assumptions ```text Not applicable: the relevant product is free. pandas is a free open source library; no pricing page or paid plans exist. ``` ### Activation - **Pass** — An API reference or OpenAPI spec is reachable ```text API reference index lists all public pandas objects, functions and methods. ``` - **Skipped** — An MCP server is documented and well-formed ```text No MCP server documentation found in fetched pandas pages. ``` - **Skipped** — A CLI install path is documented ```text pandas is a Python library; no CLI install path documented. ``` - **Pass** — SDK packages resolve on their registries ```text PyPI registry lookup for pandas returned HTTP 200. ``` - **Skipped** — Agent skills are published ```text No agent skills published in fetched pandas documentation. ``` [Full report data](https://www.ax-check.com/pandas.pydata.org/report.json)
