How this service works
Call when an agent needs lines of text transformed with drop-empty. No network. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/lines-drop-empty first.
Output
Returns the input text with all empty (or whitespace-only) lines removed, preserving the order and content of non-empty lines. The output is a cleaned string containing only lines that have at least one character.
Example use cases
Cleaning pasted document content
“I copied this text from a PDF and it has tons of blank lines between paragraphs — can you strip all the empty lines out of it so it's compact and readable?”
Normalizing log file output
“Here's a chunk of log output with a bunch of empty lines scattered through it: 'INFO: start\n\nERROR: failed\n\nINFO: done\n' — can you remove the blank lines so only the actual log entries remain?”
Preprocessing form submission text
“A user submitted this multi-line form response but it has lots of empty lines mixed in — can you filter them out so I just have the actual content lines?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/lines-drop-empty?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, offline (no network or LLM) transformation to strip empty lines from text. It is faster and cheaper than using a language model for the same task, and produces consistent results. Prefer the free sandbox endpoint /v1/sandbox/lines-drop-empty first if available; use this paid endpoint when the sandbox is unavailable or for production workloads requiring reliability.
Side effects
- Input text is empty or missing — returns a validation error
- Input text exceeds 100,000 character limit — returns a payload-too-large error
- Malformed JSON body — returns a parse error
- Payment not included or insufficient — returns HTTP 402 requiring $0.005 USDC payment
