Regex Test

Tests a JavaScript regex against sample inputs and shows exactly what matched.

Overview

Tests a JavaScript regex against sample inputs and shows exactly what matched. Takes a pattern + flags and an array of test inputs, then returns a per-input matched / not-matched verdict, every match with byte index, all numbered capture groups, and named groups (?<name>...). Catches catastrophic-backtrack-shaped patterns up front (nested unbounded quantifiers) and rejects them with a clear error. Companion to regex-from-prompt: that one generates a pattern from natural language, this one tells you whether your pattern actually matches what you think it matches. Use it as a regex tester, pattern matcher, regex playground, verify-a-pattern check, or match-and-capture extractor.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/regex-test \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/regex-test \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
