Dev Regex Tester

by AgentsToolsHub in Developer tools

x402 APIPassing, checked 43 min ago

Test a regular expression against text and see every match: the matched substring, its index, and all capture groups. Deterministic — the same pattern and text always produce the same result, unlike LLM-simulated regex matching. Use this when an agent needs to pattern + text → every match, group and index.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://agentstoolshub.com/api/v1/dev/regex-tester?flags=g&pattern=%5B%5Cw.%2B-%5D%2B%40%5B%5Cw-%5D%2B%5C.%5B%5Cw.%5D%2B&text=Contact+jane%40acme.io+or+bob%40test.org+today'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://agentstoolshub.com/api/v1/dev/regex-tester?flags=g&pattern=%5B%5Cw.%2B-%5D%2B%40%5B%5Cw-%5D%2B%5C.%5B%5Cw.%5D%2B&text=Contact+jane%40acme.io+or+bob%40test.org+today' \
