# Regex Tester API
[](https://regex-generator.api.klymax402.com/mcp)
[](https://x402.org)
[](LICENSE)
Test regex patterns against strings. Get all matches, capture groups, positions, and plain-English pattern explanations. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
## Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
```json
{
"mcpServers": {
"regex-generator": {
"url": "https://regex-generator.api.klymax402.com/mcp"
}
}
}
```
## Quickstart -- HTTP (x402)
```bash
curl -X POST "https://regex-generator.api.klymax402.com/api/test" \
-H "Content-Type: application/json" \
-d '{"pattern":"...","testStrings":"..."}'
# -> 402 Payment Required, with an x402 payment challenge in the response body
```
Any x402-aware client ([`@x402/fetch`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.
## Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
| `text_test_regex` | POST | `/api/test` | $0.003 | Test a regex pattern against input strings |
### `text_test_regex`
Use this when you need to test a regular expression against one or more strings. Returns all matches, capture groups, positions, and a human-readable explanation of the pattern.
**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
| `pattern` | string | yes | Regular expression pattern (without delimiters) |
| `flags` | string | no | Regex flags: g, i, m, s, u (default: g) |
| `testStrings` | array | yes | Array of strings to test against the pattern |
Example response:
```json
{"pattern":"\d{3}-\d{4}","flags":"g","explanation":"Matches 3 digits, a hyphen, then 4 digits","results":[{"input":"Call 555-1234","matched":true,"matches":[{"value":"555-1234","index":5,"groups":[]}]}],"totalMatches":1}
```
**When to use**: validating regex patterns before deploying them in code, debugging why a pattern fails to match, or extracting structured data from text. Use this BEFORE writing complex regex into production code.
**Not for**: text classification (use `text_classify_content`), PII detection (use `privacy_detect_pii`), text comparison (use `text_compare_diff`).
