How this service works
Call when an agent needs lines of text transformed with number. No network. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/lines-number first.
Output
Returns the input text with each line prefixed by its sequential line number, enabling easy reference to specific lines within the content. The response is computed locally with no external network requests.
Example use cases
Numbered code snippet for review
“Take this Python code snippet and add line numbers to each line so reviewers can refer to specific lines easily: 'def foo():
x = 1
return x'”
Annotated log output for debugging
“I've got a raw log dump and I need every line numbered so I can reference them in my bug report — here's the log text: 'INFO server started
WARN disk usage high
ERROR connection refused'”
Formatted prose for editorial markup
“Please number each line of this paragraph draft so my editor can give me line-by-line feedback: 'The sun rose slowly.
Birds began to sing.
The town came alive.'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/lines-number?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, deterministic, offline transformation that prefixes sequential line numbers to each line of a text block. It is ideal for formatting code snippets, log files, or prose for review, and is preferred over building custom numbering logic when a cheap, reliable micro-service call is acceptable. Use the free sandbox POST /v1/sandbox/lines-number first if available to avoid cost during testing.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Payment of exactly $0.003 USDC required; incorrect payment amount results in 402 error
- Malformed request body returns 400 bad request
