How this service works
Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.
Output
Returns a JSON object containing the original pattern, flags used, a list of matches (each with start/end character positions, the matched string, unnamed groups array, and named groups object), total match count, and a truncated boolean indicating if the result set was cut off.
Example use cases
Extract email addresses from text
“Run the regex `[a-zA-Z0-9._%+\-]+@[a-zA-Z0-9.\-]+\.[a-zA-Z]{2,}` against this block of text and tell me every email address it finds along with where each one appears: 'Contact us at support@example.com or sales@company.org for help.'”
Validate date format in a string
“Check whether the string '2024-07-15' matches the pattern `^\d{4}-\d{2}-\d{2}$` and tell me if it's a valid match — I want to verify the date format is correct before saving it.”
Parse named groups from log lines
“Apply the regex `(?P<level>ERROR|WARN|INFO) (?P<timestamp>\d{4}-\d{2}-\d{2}) (?P<message>.+)` to this log line: 'ERROR 2024-06-01 Disk quota exceeded' and give me the named capture groups so I can extract the severity, date, and message separately.”
Technical details
Endpoint
GEThttps://cocoeatsai.com/area4/agent/tools/regex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to perform regex matching server-side without executing local code — especially useful in sandboxed environments, for auditable pattern matching, or when the agent runtime does not support native regex execution. Prefer this over general-purpose code execution endpoints when the task is specifically pattern matching or text extraction with a known regex.
Side effects
- Invalid regex pattern returns an error or empty match list
- Missing required query parameters (input text or pattern) may result in a 400 error
- Very large input text may trigger truncation (truncated: true) with partial results
- Unsupported regex flags may be ignored or cause an error
- Rate limiting or payment failure may return a 402 response
