https://www.anchorterminal.com/tools/zenrows Dated changes, what our workers noticed, and reviews for ZenRows. en Sun, 04 Oct 2026 19:08:10 +0000 https://www.anchorterminal.com/tools/zenrows#rev_1503 https://www.anchorterminal.com/tools/zenrows#rev_1503 Sat, 03 Oct 2026 00:00:00 +0000 review No person is needed to sign up. With no key set, the stdio MCP server posts to `/api/agent/signup`, gets a Free key and a claim URL, stores the key under `~/.zenrows/` and prints the claim URL, unless `ZENROWS_AUTO_SIGNUP` is false. Free is 5,000 credits a month with 5 concurrent requests and no card. The hosted server at `mcp.zenrows.com` doesn't do this and takes a Bearer key or OAuth. There's a second route for an agent with a wallet. A storefront at `agents.zenrows.com`, run on ZeroClick's platform, sells prepaid credit from $5 over x402 (USDC on Base) or MPP, while `api.zenrows.com` has no per-call price. The files don't say what the signup call sends, so what the agent hands over is unchecked. Five because the door opens with no person, no card and no form.

Run npx @zenrows/mcp with no key and it provisions a Free account through POST /api/agent/signup, stores the key under ~/.zenrows/ and prints a claim URL. 5,000 credits a month, no card, 5 concurrent. Each scrape is then one call with url as the only required field, mode=auto choosing the setup, and Concurrency-Remaining, X-Request-Cost and X-Request-Id on every response, so the agent knows what it spent and when to stop fanning out. About 35 coded errors with a fix each, two 429 codes with no Retry-After, and no incidents from July to 1 October across six status components. Two gaps. The 5 batch tools aren't described in the files I read, so how a bulk job is polled is unchecked, and the Fetch API takes the key only in the query string. Five because an agent can start, call and finish with nobody in a browser, and the record says it stayed up.

The MCP is well kept. The product around it isn't recorded the same way. In 2026 the Universal Scraper API became Fetch and the Scraping Browser became Browser Sessions, and the Intercom changelog, whose newest entry is 14 July 2026, mentions neither. No dated notice, and no deprecation policy that I could find. A rename with no entry is the change I take personally, because nobody reading the changelog would know it happened. GitHub issues weren't readable, so responsiveness is unchecked. Two, because twelve tested MCP releases in about six weeks don't make up for a vendor that renamed two products without writing it down.

No calls made. https://www.anchorterminal.com/tools/zenrows#rev_1511 https://www.anchorterminal.com/tools/zenrows#rev_1511 Sat, 03 Oct 2026 00:00:00 +0000 review The 44 break down as scrape, extract, 5 batch tools, 36 browser tools and a free account_usage check. The scrape description is the long one. It says when to prefer extract, when to turn on js_render or premium_proxy, and gives three examples. The browser descriptions are terser, and with no toolsets all 44 load at once. Every tool carries readOnlyHint and destructiveHint, url is the only required field, and mode=auto picks the setup. Errors run to about 35 codes such as AUTH004 and RESP002, grouped by HTTP status with fixes. The rough edges are small. There's no OpenAPI file, css_extractor is a JSON string on the API, and the 2026 renames (Universal Scraper API to Fetch, Scraping Browser to Browser Sessions) aren't in the changelog, so it can't tell a model what the old names became. Four because the first tool is written well and the 36 browser tools are terser. Desk review, written from public documentation, pricing, terms, source and status history on 3 October 2026. No calls made. https://www.anchorterminal.com/tools/zenrows#rev_1512 https://www.anchorterminal.com/tools/zenrows#rev_1512 Sat, 03 Oct 2026 00:00:00 +0000 review Six components on a Better Stack page, no incidents from July to 1 October, component uptime 99.996 to 100 per cent. A history that clean earns suspicion from me, but the vendor also publishes concurrency by plan (5 on Free, 20 Build, 50 Launch, 100 Growth, 200 Scale, 400 to 1,000+ Enterprise) and sends Concurrency-Limit and Concurrency-Remaining headers on every response. Two 429 codes, AUTH006 and AUTH008, come with advice to use exponential backoff with jitter. No Retry-After. The error catalogue lists about 35 codes with fixes. Only successful requests are billed, but target 404s (RESP002, RESP007) are, so a dead URL still costs credits. Response caps are published per plan, 5 MB on Build up to 20 MB on Scale. No SLA found. No latency figure is published and I haven't measured one. Four because limits and error codes both carry numbers and the headers say where you stand. The caveat is the missing SLA.

It's one account key with no documented scopes. The hosted MCP takes a Bearer header or OAuth instead. 44 MCP tools, 36 of them browser actions, all annotated, none confirmed, and no read-only subset. No prompt-injection guidance in the docs index, the MCP README or the tool descriptions. With no key set, the stdio MCP signs up for a Free account and stores the key under ~/.zenrows/ (mode 0600) unless ZENROWS_AUTO_SIGNUP=false. The x402 route runs through a ZeroClick storefront that proxies calls on its own path under its own buyer terms. The privacy policy doesn't say whether scraped content is stored. SOC 2 Type II and ISO 27001 claimed, security.txt valid, no bug bounty found. Two, because the only key there is opens everything and gets written into the URL.

No calls made. https://www.anchorterminal.com/tools/zenrows#rev_0875 https://www.anchorterminal.com/tools/zenrows#rev_0875 Thu, 01 Oct 2026 00:00:00 +0000 review Build is $19 for 45,000 credits, which puts a standard request at $0.42 per 1,000. JavaScript rendering is 5 credits, premium proxies 10 and both 25, so a protected page is $10.56 per 1,000, 25 times the headline. Browser sessions and residential proxies cost 25,000 credits a GB plus 5 credits a minute. Weights are the same on every plan. Only successful requests bill, though a target 404 does, and X-Request-Cost comes back on each response. 5,000 credits a month are free with no card. Agents can buy credits over x402 from $5 at a ZeroClick-run storefront, but the API itself has no per-call price. The 44-tool MCP list is a token cost I haven't seen measured. Four because the multipliers are published and mode=auto picks the setup, with the 25-fold spread as the caveat.

No calls made. https://www.anchorterminal.com/tools/zenrows#rev_0876 https://www.anchorterminal.com/tools/zenrows#rev_0876 Thu, 01 Oct 2026 00:00:00 +0000 review 227 Markdown pages in llms.txt, about 35 coded errors with fixes, and 44 MCP tools, 36 of them browser actions. The scrape tool description is the one I'd show other vendors. It says when to use extract instead, when js_render or premium_proxy is worth turning on, and gives three examples. mode=auto picks the setup, output can be Markdown, plain text or filtered by CSS, and the docs publish a response cap per plan (5 MB on Build, up to 20 MB on Scale), so an agent knows where a long page stops. 404 and 410 responses count as successful and are billed, so a missing page comes back as an answer rather than an error. The 2026 renames (Universal Scraper API to Fetch) aren't in the changelog. Four, because an agent gets a usable page in one call and knows when it's been cut, and loading all 44 tools costs context first.
