POST /v1/reduce/minimize

unprobed

Given a source bundle, entry file, command, and failure predicate (exit code and/or stdout/stderr patterns), runs a deterministic delta-debugging reducer in a network-isolated sandbox and returns the reduced bundle and entry that still reproduce the failure, plus a replay script and run log. Scoped to a local minimum under the passes listed, never a proof of global minimality.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
