KasadaWorkTimeProxyLess
Mint the per-request x-kpsdk-cd proof-of-work for a Kasada session you already hold.
Once a Kasada session exists, some sites additionally require an x-kpsdk-cd header on every protected request. It is a proof-of-work computed from the session's x-kpsdk-st timestamp: cheap, single-use, and unrelated to solving the challenge itself. This task mints one.
You need it only when the browser sends x-kpsdk-cd on the requests you are reproducing. Check DevTools first.
Never reuse a cd value
Generate a fresh x-kpsdk-cd immediately before each protected request. Replaying one across requests fails.
Where st comes from
st is the x-kpsdk-st response header from the /tl POST: either the one you made with
KasadaTlPayloadProxyLess or
KasadaPayloadProxyLess, or the value returned in the solution of a managed
solve. Send the same userAgent the session was opened with.
