[ 01 ]What it looks like

Either nothing, or the familiar v2 checkbox and photo grid, depending on the key type.

[ 02 ]Why it is hard

Enterprise adds an enterprisePayload object, usually a single s value, and often moves the API domain to recaptcha.net. Both have to be replayed exactly or the backend refuses the token inside assessments.create. The verdict is server-side and carries reason codes, so a token that passes on a plain v2 key can still be refused here with no visible challenge failure.

[ 03 ]How we solve it

The task accepts enterprisePayload and apiDomain and passes both through untouched, including keys served from recaptcha.net. Checkbox and score-based Enterprise keys both route to the Enterprise worker pool, which is measured on accepted rate at the target rather than on token validity. When a key starts producing tokens the target refuses, the pool behind it is rotated and the refused attempts are not billed.

[ 05 ]Questions about this one

Questions about this one

Look for grecaptcha.enterprise in place of grecaptcha in the page scripts, or a script tag loading enterprise.js. Enterprise keys also frequently serve from recaptcha.net rather than google.com, and that host is the apiDomain you pass through.

It is an object the site adds to the render call, most often a single s value. Send it whenever the page sets one, because the backend replays it into assessments.create and refuses tokens generated without it. If the page has no s value, omit the field.

$1.50 per 1,000 solved tokens, the same rate as plain v2. Median 6.1 seconds, 95th percentile 13.9 seconds, 98.8% success. The extra time is payload and apiDomain handling, not a slower queue.

Yes. Enterprise keys come in checkbox and score flavours. Checkbox keys use the Enterprise v2 task type; score keys take pageAction and minScore the way v3 does, and are billed at the same Enterprise rate.
