ZenRows
DEVELOPER · DEVELOPER
Pages fetched through the proxy, batch scraping jobs, and the plan behind their key.
Connect ZenRows with Fabriq Developer
Your user pastes their ZenRows credential on a page Agentic Fabriq hosts, so it never reaches your backend and never becomes one shared key across all of your users. Same call as OAuth, one more argument.
Provider names are surfaces, not vendors, and the authoritative list is the capabilities endpoint rather than any page including this one — an unknown name returns 400 with the valid list. Fabriq Developer is free to start and needs no provider paperwork. Start free or read the quickstart.
Connecting ZenRows in practice
ZenRows prices one request between 1 and 25 credits depending on what you turn on — 1 standard, 5 for JavaScript rendering, 10 for premium proxies, 25 for both — so a single flag change makes a crawl 25 times more expensive. Concurrency is a hard ceiling rather than a rate: on the Free tier the sixth simultaneous request 429s immediately, however slowly you are pacing.
Rate limits
- Concurrency by tier: Free 5, Build 20, Launch 50, Growth 100, Scale 200, Enterprise custom from 400 to 1,000+.
- Credit weights per successful request: standard 1, JavaScript Rendering 5, Premium Proxies 10, JS Rendering plus Premium Proxies 25. These weights are fixed on every plan.
- Residential Proxies and Browser Sessions bandwidth meters at 25,000 credits per GB; Browser Sessions add 5 credits per minute of session time.
- Maximum response size per tier: Free 10 MB, Build 5 MB, Launch 10 MB, Growth 10 MB, Scale 20 MB.
Worth knowing
- A 429 here means you are out of concurrent slots, not out of requests per minute, so backoff has to be driven by in-flight count rather than by a timer.
- You are charged only for successful requests, and HTTP 404 and 410 count as successful because the request completed and returned valid data.
- The Build tier caps a single response at 5 MB — lower than the Free tier’s 10 MB — so upgrading from Free can shrink the largest page you can fetch.
- One shared credit balance covers Fetch, Extract, Batch and Browser Sessions, so a runaway browser session drains the budget for scraping.

What an agent can do
Each action is granted on its own. An agent allowed to read is not thereby allowed to write, and the scope beside each row is what the acting user must have connected for it to run at all.
