How this service works
BitBooth Regex Test: pay 0.001 USDC, safely compile and run a regex against a corpus. Returns structured matches with capture groups, indices, and lengths. JS engine flags (g, i, m, s, u, y, d). Hard CPU deadline guards against catastrophic backtracking (ReDoS) — `regex_timeout` is reported instead of stalling. Stateless, no API key.
Output
A structured JSON response containing an array of matches, each with the full match string, an array of capture group values, the zero-based start index in the corpus, and the match length. If the regex execution exceeds the CPU deadline due to catastrophic backtracking, a `regex_timeout` flag is set instead of stalling indefinitely.
Example use cases
Extract dates from log file
“Run the regex /(\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2})/ with the 'g' flag against this server log text and return all timestamp matches with their capture groups and character positions: '[2024-01-15T12:34:56] ERROR: disk full\n[2024-01-15T12:35:01] INFO: retry'”
Validate email pattern against user list
“Test the regex /^([\w.+-]+)@([\w-]+\.[\w.]+)$/ with the 'gm' flags against this list of email addresses and tell me which ones match and what the capture groups are: 'alice@example.com\nnot-an-email\nbob.jones@company.co.uk'”
Guard against catastrophic backtracking
“I have a potentially dangerous regex pattern /(a+)+$/ — can you safely run it against the string 'aaaaaaaaaaaaaaaaaaaaaaab' using your ReDoS-protected regex tester and tell me if it times out or returns matches?”
Technical details
Endpoint
POSThttps://app.heinrichstech.com/v1/cdp/regex-test?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to safely execute JavaScript regex patterns — especially untrusted or user-supplied patterns — against a text corpus without risking server-side ReDoS hangs. Ideal for agents that need structured match data (capture groups, indices, lengths) rather than a simple boolean match. The hard CPU deadline makes it safe for production use with arbitrary patterns. Prefer it over client-side execution when you need a stateless, auditable, pay-per-use match service with no API key management.
Side effects
- Catastrophic backtracking / ReDoS: returns regex_timeout flag instead of hanging
- Invalid regex syntax: returns a compile error
- Invalid JS flags: returns a validation error
- Payment not included or insufficient: returns 402 Payment Required
- Malformed request body: returns 400 Bad Request
