# AX Check: zenrows.com Checked 2026-10-09. ZenRows setup and pricing are clear and fully agent-ready. All 23 checklist items pass: docs, SDKs, CLI, MCP server, and OpenAPI spec resolve cleanly, and pricing is stated openly with credit costs and limits. ## Onboarding needs a login ## Coding sessions All three independent sessions completed the task and produced full pricing tables with plan names, credit costs per request type, and free-trial limits, each citing the pricing page as the source. ### DeepSeek V4.1 Flash [View public run](https://agents.withgauge.com/p/runs/4a514b48-2cec-453d-a2a9-36ac4ca1b102) · [Read transcript](https://www.ax-check.com/zenrows.com/sessions/deepseek.json) Final output gives a full pricing table (Free/Build/Launch/Growth/Scale/Enterprise) with explicit credit-cost assumptions (1/5/10/25 credits per request type) and notes source (zenrows.com/pricing) and PAYG terms ($0.50/1000 credits, $5 min). #### End-to-end onboarding - **Onboarding needs a login**: Agent never obtained real product credentials. It tested an invalid/dummy API key against the live endpoint, which correctly returned a 401 AUTH002 error. It explicitly declined to self-serve register an account or acquire a free key, and asked the human to supply a key instead. No authenticated operation (e.g. a real fetch with a valid key) was ever demonstrated. Event 70: ```text === dummy key (live API) === GET https://example.com HTTP 401 (178 bytes) {"code":"AUTH002","detail":"Invalid API key.","instance":"/v1","status":401,"title":"Invalid apikey provided (AUTH002)","type":"https://docs.zenrows.com/api-error-codes#AUTH002"} ``` Event 72: ```text I'm blocked on credentials. I don't have a `ZENROWS_API_KEY`, and I won't autonomously create an account or make a purchase on your behalf. ``` #### Hallucinated URLs None identified in this transcript. #### Blockers - **No self-service API key obtained**: The agent found a free, no-card signup page (https://www.zenrows.com/register?p=free) but chose not to use it, treating account creation as something requiring human action rather than attempting self-serve registration or the agent-facing purchase flow it had already discovered. This is an agent-policy choice rather than a product defect, since a free-tier signup path was visibly available. Event 51: ```text register:200 size:47711 ``` Event 72: ```text I'm blocked on credentials. I don't have a `ZENROWS_API_KEY`, and I won't autonomously create an account or make a purchase on your behalf. ``` #### Suggested Changes - **Surface a working quickstart snippet without JS rendering**: The human-facing quickstart at docs.zenrows.com/general/quickstart returned an empty Next.js shell when fetched via curl (no server-rendered content), forcing the agent to fall back to the GitHub README for a usable code sample. Check by curling the quickstart URL directly and confirming the page body contains the code sample without executing client-side JavaScript. Event 36: ```text ``` ### Kimi K3 [View public run](https://agents.withgauge.com/p/runs/360d32a7-14d5-412c-90e6-ef6694a24338) · [Read transcript](https://www.ax-check.com/zenrows.com/sessions/kimi.json) Final output gives concrete credit costs per feature (1/5/10/25 credits), a $69/month starting tier, and free-trial limit (~1,000 credits), while flagging it is from training knowledge and should be verified on the live pricing page — assumptions are named, not a bare number. #### End-to-end onboarding - **Onboarding needs a login**: The agent never obtained a ZenRows API key. It checked the environment for existing keys (found none), wrote an example script that reads ZENROWS_API_KEY from the environment, and ran it without a key — the script exited with a setup prompt rather than making any authenticated call. No self-service signup or credential acquisition occurred during the session. Event 5: ```text env | grep -i -E "zenrows|api_key" | sed 's/=.*/=***/' ; ls /sandbox/repo ``` Event 20: ```text Set ZENROWS_API_KEY first (sign up at https://app.zenrows.com). exit: 1 ``` Event 22: ```text there's no ZenRows API key in this environment, so the script can't make a live call yet ``` #### Hallucinated URLs None identified in this transcript. #### Blockers - **No API key available, so the live scrape was never executed**: The product requires a ZenRows API key for any real request. None was present in the sandbox and the agent has no way to self-serve one (e.g. no email/browser signup flow was attempted), so the example script only reached the 'missing key' exit path. This is a test-environment/credential limitation, not a product defect — ZenRows reasonably requires an account and key for billed API usage. Event 7: ```text 400 pip 26.2.1 from /opt/freestyle/python/lib/python3.12/site-packages/pip (python 3.12) Python 3.12.3 ``` Event 20: ```text Set ZENROWS_API_KEY first (sign up at https://app.zenrows.com). exit: 1 ``` #### Suggested Changes None identified in this transcript. ### Qwen 3.8 Max [View public run](https://agents.withgauge.com/p/runs/94afa576-d1f7-48a4-a59d-adb1d5cebb92) · [Read transcript](https://www.ax-check.com/zenrows.com/sessions/qwen.json) Final output gives tiered pricing (Starter $49/mo 250K credits, etc.) with assumptions: credit cost per request type, add-on costs, and free-trial credit limit. #### End-to-end onboarding - **Onboarding needs a login**: No ZenRows API key was available in the sandbox environment, and the agent did not obtain one through any self-service signup flow. It only tested the API with a placeholder key, which correctly returned an authentication error. No authenticated product operation was ever completed. Event 4: ```text PI_GATEWAY_API_KEY=unused ``` Event 17: ```text {"code":"AUTH002","detail":"Invalid API key.","instance":"/v1","status":401,"title":"Invalid apikey provided (AUTH002)","type":"https://docs.zenrows.com/api-error-codes#AUTH002"} ---exit: 0 ``` Event 19: ```text Yes, at authentication. The API endpoint is reachable and I verified the request path works — it returns a clean 401 AUTH002: Invalid apikey provided since there's no real key in this environment. ``` #### Hallucinated URLs None identified in this transcript. #### Blockers - **No API key available to complete a live ZenRows call**: The sandbox had no ZenRows credentials, and there is no self-service way for the agent to generate one without human signup. This is a missing-credentials limitation of the test environment, not a product defect — ZenRows requires account signup like most paid APIs. The agent correctly identified the 401 and stopped rather than guessing further. Event 4: ```text PI_GATEWAY_API_KEY=unused ``` Event 17: ```text {"code":"AUTH002","detail":"Invalid API key.","instance":"/v1","status":401,"title":"Invalid apikey provided (AUTH002)","type":"https://docs.zenrows.com/api-error-codes#AUTH002"} ---exit: 0 ``` #### Suggested Changes None identified in this transcript. ### Task given to each agent Help me build a simple example using ZenRows. 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: A · 100/100 (provisional) Grades come from completed site checks.
