Not responding. This endpoint did not answer its last liveness check (2026-10-13). It may be temporarily down.
Mirrored from Coinbase's public x402 Bazaar. The description is the provider's own text and has not been reviewed here; the payment requirements are copied as published.
What it does
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.

For humans
You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
