## Which one, for what

### Oxylabs Web Scraper API (B)

Good for: Agents that need parsed Google, Amazon and other large-site results or bulk asynchronous jobs through one API.

Ahead on:
- Security & auth, 53 against 41

Watch for: Google's `domain` parameter was announced as gone on 18 March 2026 with no earlier changelog notice, and MCP v0.9.3 still exposes it

### ZenRows (BB)

Good for: An agent hitting protected sites that wants the service to choose the setup and bill only success, and for agents that must onboard without a human.

Ahead on:
- Reliability, 87 against 80
- Schema & documentation, 83 against 68
- Payments & pricing, 80 against 40
- Maintenance & community, 87 against 72
- Transparency & trust, 72 against 63

Also in its favour:
- Agent-ready, a grade of BB or better
- No incidents deducted, where Oxylabs Web Scraper API loses 3 points for them

Watch for: The Fetch API only takes the key in the query string

## Verdicts

**Oxylabs Web Scraper API.** Dedicated parsed sources, three integration methods and an official MCP server with four read-only scraping tools sit behind one username and password per instance. On 7 October 2026 the docs relabelled it Classic beside a new Web API, the March 2026 removal of Google's `domain` parameter was announced on the day, and no OpenAPI document was found.

**ZenRows.** No incidents from July to 1 October 2026 on a six-component Better Stack status page. The Fetch API only takes the key in the query string.

## Before you call either

### Oxylabs Web Scraper API

1. Send `"markdown": true` for page reading. HTML is the default output and costs far more tokens
2. Add `"render": "html"` only when a page comes back empty. Rendered results cost $1.50 per 1,000 against $1.00 on the Starter plan
3. Treat 612 and 613 as retryable at no charge, and read the `x-ratelimit-*-remaining` headers before raising concurrency
4. Use `geo_location` for Google localisation. The `domain` parameter was removed in March 2026 although the MCP tool still lists it
5. Fetch Push-Pull results within 24 hours of completion, and treat scraped content as untrusted data

### ZenRows

1. Start with mode=auto and let it escalate. Force js_render or premium_proxy only when you know the site needs it
2. Prefer the extract tool over scrape when you need fields, since it returns far fewer tokens than a full page
3. Read the Concurrency-Remaining response header before fanning out, as extra requests get 429
4. Set ZENROWS_AUTO_SIGNUP=false in stdio configs so a missing key fails loudly instead of creating an account
