mirrored listing x402 eip155:8453

Test whether a RE2 pattern matches anywhere in the input

Test whether a RE2 pattern matches anywhere in the input. Returns { matched }. RE2 guarantees linear-time evaluation, so this is safe against catastrophic backtracking. An invalid pattern is a clean 400; no match is a successful 200.
