## 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 scriptmasterlabs-acp-x402-regex-test-93bcad16
```

Example prompt: Can you test whether the regex pattern ^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$ matches the string 'user@example.com' using the ScriptMasterLabs regex test endpoint?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call regex testing capability without setting up your own infrastructure, especially in agent workflows that already use x402/USDC micropayments on Base. Ideal for one-off pattern validation tasks within automated pipelines.

## Known failure modes

- Invalid or malformed regex pattern causes a parsing error
- Missing required 'properties' parameter returns a bad request response
- Service unavailable on Render cold start causing timeout
- Payment not settled in USDC results in 402 Payment Required response
- Empty input string may return no match rather than an error

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns a result indicating whether the provided string matches the given regex pattern, along with any match details or validation outcome.
