The x402 challenge came back with no payment requirements in our probe.\n\n**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.\n\n## Before you call either\n\n### Olostep\n\n1. For more than a handful of URLs use /v1/batches, then page results with the cursor\n2. Pass `storage.expires_in` if you need results after about 7 days\n3. Don't ask for json output without a `parser` or an `llm_extract` schema\n4. Hosted MCP wants `Authorization: Bearer`, stdio wants OLOSTEP_API_KEY. Mixing them up shows 0 tools\n5. Check the 402 body before paying over x402. Our probe got an empty one\n\n### ZenRows\n\n1. Start with mode=auto and let it escalate. Force js_render or premium_proxy only when you know the site needs it\n2. Prefer the extract tool over scrape when you need fields, since it returns far fewer tokens than a full page\n3. Read the Concurrency-Remaining response header before fanning out, as extra requests get 429\n4. Set ZENROWS_AUTO_SIGNUP=false in stdio configs so a missing key fails loudly instead of creating an account\n\n## Other comparisons with Olostep or ZenRows\n\n- [Bright Data vs Olostep](https://www.anchorterminal.com/compare/bright-data-vs-olostep.md)\n- [Bright Data vs ZenRows](https://www.anchorterminal.com/compare/bright-data-vs-zenrows.md)\n- [Jina Reader vs Olostep](https://www.anchorterminal.com/compare/jina-reader-vs-olostep.md)\n- [Jina Reader vs ZenRows](https://www.anchorterminal.com/compare/jina-reader-vs-zenrows.md)\n- [Olostep vs Scrape.do](https://www.anchorterminal.com/compare/olostep-vs-scrape-do.md)\n- [Olostep vs ScrapeGraphAI](https://www.anchorterminal.com/compare/olostep-vs-scrapegraphai.md)\n- [Olostep vs Scrapeless](https://www.anchorterminal.com/compare/olostep-vs-scrapeless.md)\n- [Olostep vs Scrapfly](https://www.anchorterminal.com/compare/olostep-vs-scrapfly.md)\n- [Olostep vs ScrapingAnt](https://www.anchorterminal.com/compare/olostep-vs-scrapingant.md)\n- [Olostep vs ScrapingBee](https://www.anchorterminal.com/compare/olostep-vs-scrapingbee.md)\n- [Olostep vs Scrapingdog](https://www.anchorterminal.com/compare/olostep-vs-scrapingdog.md)\n- [Olostep vs Spider](https://www.anchorterminal.com/compare/olostep-vs-spider-cloud.md)\n- [Scrape.do vs ZenRows](https://www.anchorterminal.com/compare/scrape-do-vs-zenrows.md)\n- [ScrapeGraphAI vs ZenRows](https://www.anchorterminal.com/compare/scrapegraphai-vs-zenrows.md)\n- [Scrapeless vs ZenRows](https://www.anchorterminal.com/compare/scrapeless-vs-zenrows.md)\n- [Scrapfly vs ZenRows](https://www.anchorterminal.com/compare/scrapfly-vs-zenrows.md)\n- [ScrapingAnt vs ZenRows](https://www.anchorterminal.com/compare/scrapingant-vs-zenrows.md)\n- [ScrapingBee vs ZenRows](https://www.anchorterminal.com/compare/scrapingbee-vs-zenrows.md)\n- [Scrapingdog vs ZenRows](https://www.anchorterminal.com/compare/scrapingdog-vs-zenrows.md)\n- [Spider vs ZenRows](https://www.anchorterminal.com/compare/spider-cloud-vs-zenrows.md)\n- [Firecrawl MCP vs Olostep](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-olostep.md)\n- [Apify MCP Server vs Olostep](https://www.anchorterminal.com/compare/apify-mcp-vs-olostep.md)\n- [Firecrawl MCP vs ZenRows](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-zenrows.md)\n",
