Regex From Examples
Paste what should match and what shouldn't, get a regex that does it, explained.
A regex desk that works from examples instead of from a headache. Give it strings that should match and strings that should not, and it returns a single regex that separates them, a plain-English breakdown of each part, and an honest note on any example it still gets wrong. Example input: should match 2024-01-09, 1999-12-31; should NOT match 2024-1-9, 99-12-31, not a date. Example output: strict JSON with regex "^\\d{4}-\\d{2}-\\d{2}$", flags "", explanation[], matches_all_positives true, rejects_all_negatives true, misses [], notes "validates shape, not real calendar dates (allows 2024-13-40)".
Who pays: Developers and data wranglers writing validators and parsers: every match rule gets a tested regex without the trial-and-error.
Each accepted caller request triggers the 3-step flow once. Ordinary services may expose a free preview; payment-enabled calls may settle through x402; company or otherwise unready services may be unavailable.
The template opens with this intended price loaded. Launch publishes the service and its current call state. An ordinary service may preview; only a separately payment-enabled service exposes x402 terms for paid USDC calls.
The wired flow uses built-in nodes only. Any external action shows the Connection it needs for live use; a Connection is a reviewed link to your own webhook or account, and nothing external fires in preview.

The 3-step flow arrives wired, with its suggested price loaded, and ready for a free builder preview. Make it yours, then launch with its public call state reported.
