How this service works
Call when an agent needs JWT-shaped tokens (no verify) extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/regex-jwt first.
Output
A list of up to 20 JWT-shaped token strings (matching the header.payload.signature pattern) found in the input text. If no tokens are found, an empty list is returned. Note: tokens are matched by shape/regex only and are not cryptographically verified.
Example use cases
JWT extraction from server logs
“I have a big server access log here — can you pull out every JWT token you find in it? Here's the text: 'GET /api/data HTTP/1.1\nAuthorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIn0.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c\n...'”
Security audit of request payloads
“I'm auditing some captured HTTP request payloads for accidentally exposed JWTs — can you scan this batch of request data and list every JWT-shaped token you find?”
Token harvesting from debug output
“Here's some debug output from our app — can you find and list all the JWT tokens embedded in it so I can check which sessions were active?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/regex-jwt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly extract JWT-shaped tokens from raw text such as logs, HTTP dumps, or documents without any network calls or LLM inference. Prefer the free sandbox POST /v1/sandbox/regex-jwt first if available; use this paid endpoint only when the sandbox is unavailable or rate-limited. Do not use this if you need to verify or decode JWT contents — it only performs regex matching on token shape.
Side effects
- Empty match list returned when no JWT-shaped strings are present in the text (still billed $0.006)
- Input text exceeds 100,000 character limit, causing request rejection
- Only up to 20 matches returned even if more JWTs exist in the text
- Regex matches JWT-shaped strings that are not real/valid JWTs (no signature verification)
- Network or payment authorization failure resulting in no response
