Regex test

POST /api/regex-test

Test a regex against an input string. Returns every match, the position, and any capture groups (named and numbered). Useful for debugging patterns.

Tests a regex pattern against the input and returns every match. For each match you get: - The matching substring. - The starting index in the input. - An array of capture-group values (`$1`, `$2`, …). - A map of named-group values (`?<name>` syntax). Pattern flags work the same way as in JavaScript: `g` (global, default — must be set to find more than the first match), `i` (case-insensitive), `m`, `s`, `u`.

Inputs

Name	Type	Default	Description
pattern*	string	—	Regex pattern (without slashes).
text*	string	—	Text to search.
flags	string	""	Regex flags (e.g. `i`, `im`, `iu`). The `g` flag is always added.

Response

Modes: json. Cache: yes (24h TTL).
