Quartermaster Regex Matcher

Use this endpoint when you need deterministic, server-side regex matching with structured capture group output — particularly when you need both numbered and named groups returned in a machine-readable format. Prefer this over client-side regex when the agent cannot execute code locally, or when you need a reliable, reproducible extraction step in a workflow pipeline.

• Invalid regex pattern syntax — returns an error indicating the pattern could not be compiled
• Text exceeds 20,000 character limit — request rejected with validation error
• Pattern exceeds 1,000 character limit — request rejected
• Invalid flag characters supplied — only g i m s u y are accepted
• No matches found — returns an empty matches array rather than an error
