How this service works
Call when an agent needs shebang lines extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/regex-shebang first.
Output
Returns a list of up to 20 shebang line matches (strings starting with #!) found in the input text. An empty match list is returned (and billed) when no shebangs are present. No network calls are made during processing.
Example use cases
Detect interpreters in uploaded scripts
“I've got a batch of script files concatenated into one big text block — can you pull out every shebang line so I know which interpreters they rely on?”
Audit polyglot source code
“Here's the raw content of our monorepo's main entry files all concatenated together — extract any shebang lines so we can audit which runtimes are in use.”
Validate script headers in CI pipeline
“Check this CI artifact text and pull out all the shebang lines — I need to confirm every script starts with the right interpreter path before we deploy.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/regex-shebang?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, deterministic regex-based extraction of shebang lines from text without any LLM involvement or network calls. Prefer the free POST /v1/sandbox/regex-shebang endpoint first for testing. Choose this over LLM-based extraction when you need exact regex matching, predictable cost ($0.005 USDC flat), and speed. Best for programmatic pipelines processing scripts, source code files, or shell artifacts.
Side effects
- Empty match list returned (still billed) if no shebang lines are present in input
- Text exceeding 100,000 characters will be rejected
- Empty or missing text field returns validation error
- Payment of exactly $0.005 USDC required; missing or incorrect payment results in 402 response
