## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability moneytools-regex-tester-1b3e39bd
```

Example prompt: Run the regex (\d{4})-(\d{2})-(\d{2}) with the global flag on this text: 'due 2026-11-04 and 2026-12-01' — give me all matches with their indices and capture groups.

## When to prefer this

Choose this endpoint when you need programmatic JavaScript-compatible regex matching with structured output (match indices, capture groups) rather than a simple pass/fail. It is especially useful when you also want ReDoS safety analysis on the pattern, or when you need a regex replace operation with full match details returned. It is priced at $0.001 per call via x402 on Base after a free tier, making it suitable for automated agent pipelines that need occasional regex processing without hosting their own compute.

## Known failure modes

- Missing required 'pattern' or 'text' query parameter returns an error without charge
- Invalid regex syntax causes a parse error response without charge
- Free tier of 10 calls/day exhausted triggers HTTP 402 requiring x402 micropayment or API key
- Ambiguous or empty pattern may return zero matches without error
- Very long input text combined with complex patterns may time out

## How this service works

Regex tester: Run a JavaScript regex on text: all matches with index and capture groups, optional replace, and a ReDoS warning for nested quantifiers. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.

## Output

A JSON object containing all regex matches (each with full match text, start index, and any capture groups), optionally the replaced string if a replacement was provided, a ReDoS warning if nested quantifiers are detected, and payment metadata including whether the call was charged, the network, and the transaction ID.
