ZenRows is a Spanish web scraping platform headquartered in Madrid that lets developers collect public web data at scale without managing proxies, browsers, or CAPTCHAs. A single API key unlocks four products against a shared 55M+ residential IP pool across 190+ countries: the Universal Scraper API (HTTP scrape with JS rendering, anti-bot bypass, screenshots, CSS/AI extraction, and PDF/markdown output), the Scraping Browser (cloud Playwright/Puppeteer/CDP browser over WebSocket), Residential Proxies (HTTP/SOCKS5 with sticky sessions and country targeting), and a set of vertical Scraper APIs for Amazon, Google, Walmart, Zillow, and Idealista. ZenRows also ships first-party Python, Node.js, and Go SDKs, a Scrapy middleware, deep integrations across Playwright, Puppeteer, Selenium, Scrapy, LangChain, LlamaIndex, OpenAI Agents SDK, Zapier, n8n, Make, Pipedream, Node-RED, MuleSoft, Clay, and an official MCP server (hosted at https://mcp.zenrows.com/mcp and as @zenrows/mcp on npm) exposing scrape and 30+ browser automation tools to AI agents.
ZenRows publishes 6 API contracts indexed on the APIs.io network, including Universal Scraper API, and 5 more. Tagged areas include Web Scraping, Data Extraction, Anti-Bot, Proxies, and Residential Proxies.
The ZenRows catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
ZenRows’ developer surface includes authentication, documentation, pricing, signup flow, engineering blog, status page, changelog, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Open Source Surface applies to this provider. This product is open source and we
read its repository directly, so Open Source Surface carries
10 points of the composite. It is scored from what the repository actually
publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the
provider rather than inferred from our own catalog pointers.
This facet adds; nothing was taken away to make room for it. An open-source project is not excused from
the commercial facets, because exemption would strip it of the points it does earn.
If we have the wrong repository, or this product is not open source, say so on your
provider repo and we
will drop the facet rather than have you publish against it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 65 points between them,
because both conditional facets apply and carry
35 points together. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 65% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples+7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Delegated User Identity+6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface+6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
