Credibility concern recorded. The source reference remains available for verification and correction.

An API that solves Roblox login proof-of-work challenges over HTTPS, charging credits for successful computations.

Landing page captured for the 2026-09-14 issue.

Field notes

The documented workflow takes the three fields from a Roblox 403 proof-of-work response and posts them to `/v1/solve` with an `X-Api-Key` header. The example response returns both a computed result and the remaining balance, while the pricing model charges one credit per successful solve. The page also describes a local fallback for unusually large `t` values and says those rejected requests do not consume credits.
