Invalid by default.Valid on the first call.
Akamai's _abck cookie starts invalid and only turns valid with good sensor data. Zenrows earns the valid seal in one call.
The sensor
The sensor records everything you do.
Akamai's bmak sensor posts a payload of behavioral and device data with every request. Enough good data earns a valid cookie. Open a row.
Mouse & touch
Movement paths, click pressure, and scroll rhythm, sampled continuously. A script's input is too clean to pass.
Device & browser
Screen, GPU, fonts, and dozens of API quirks form a device signature. Headless stacks share known values.
Timing & cadence
Keystroke gaps and request intervals. Machine-perfect timing is the easiest tell of all.
Network & TLS
The TLS handshake and IP reputation place the caller. Datacenter ranges start with a trust deficit.
Session history
Behavior is scored across the whole session, not one hit. Consistency over time is what earns the seal.
Sealed valid
One call. The cookie comes back valid.
Point Fetch at an Akamai-protected property. It posts human-shaped sensor data from a real fingerprint and a trusted network, so _abck validates.
curl "https://api.zenrows.com/v1/" \ -G \ --data-urlencode "url=https://protected.example.com" \ --data-urlencode "apikey=YOUR_KEY" \ --data-urlencode "js_render=true" \ --data-urlencode "premium_proxy=true"
The seal holds, every request.
The response comes back as HTML, Markdown, or JSON, ready for your pipeline.
Akamai is one gate. Zenrows earns them all.
The same one call comes back valid behind every major anti-bot system. Point Fetch at a URL and get what's there.
