How this service works
Run a JavaScript regular expression against short text and return bounded matches without calling an upstream model. Pay up to $0.001 per request with x402 USDC on Base. Public paid calls are limited to 1500 input characters and 128 output tokens.
Output
Returns a JSON object with ok status, tool name ('regexMatch'), a summary string, the matched substrings found in the text, match count, and a fetchedAt timestamp. Results are bounded by the optional limit parameter (max 100).
Example use cases
Example prompt
“Use regex to find all matches of the pattern \b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b in this text: 'Contact us at support@example.com or sales@company.org for help' — return up to 10 matches.”

Endpoint
GEThttps://gpt55.558686.xyz/v1/tools/regex-matchWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call regex matching without a subscription, especially when processing short to medium text blocks (up to 10,000 chars) and want to pay fractions of a cent ($0.0001 USDC) per operation via x402 on Base. Prefer over full LLM-based extraction when the pattern is well-defined and deterministic regex is sufficient.
Side effects
- Missing required 'text' or 'pattern' query parameter returns 400 error
- Pattern exceeding 300 characters is rejected
- Text exceeding 10,000 characters is rejected
- Invalid regex syntax in pattern causes error response
- limit value outside 1-100 range is rejected
- Payment failure via x402 (insufficient USDC balance or wallet misconfiguration) blocks the call
- Invalid flags string (exceeding 8 chars) rejected
