How this service works
320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.
Output
Returns a result object containing regex match results such as matched substrings, captured groups, and a status field indicating success or failure of the operation.
Example use cases
Extract emails from raw text
“I have this block of text: 'Reach John at john.doe@acme.com and the team at team@startup.io' — can you run a regex to pull out all the email addresses using the pattern ([a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,})?”
Validate phone number format
“Check if the string '+1-800-555-0199' matches the pattern ^\+?[1-9]\d{1,14}$ so I know whether it's a valid international phone number format.”
Parse version numbers from log output
“I have a log line that says 'App version 2.14.3 deployed successfully' — can you use the regex (\d+\.\d+\.\d+) to extract the version number from it?”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/util/regexWhen to prefer
Choose this endpoint when you need a quick, pay-per-call regex execution without setting up your own compute environment, particularly in agentic workflows where pattern matching or text extraction is a one-off step within a larger pipeline.
Side effects
- Invalid or malformed regex pattern causes a processing error
- Input string is missing from the request body
- Regex pattern causes catastrophic backtracking, leading to timeout
- Pattern matches nothing in the input, returning empty match results
- Unsupported regex syntax or flags
