How this service works
Call when an agent needs lines of text transformed with take-20. No network. Send JSON {"text":"b\na\n"}. Exact $0.003 USDC on Base. Try unpaid POST /v1/sandbox/lines-take-20 first.
Output
The endpoint returns the first 20 lines of the submitted text, with everything after line 20 discarded. If the text has fewer than 20 lines, all lines are returned unchanged.
Example use cases
Preview long log file output
“I have a huge server log output — can you give me just the first 20 lines so I can see what's at the top without scrolling through everything?”
Truncate CSV data for quick review
“Here's a big CSV dump. Grab just the first 20 lines for me so I can check the headers and a few rows before processing the whole thing.”
Clip pasted article to first 20 lines
“I pasted this long article into my notes — can you pull out only the first 20 lines so I have a quick intro snippet?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/lines-take-20?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, deterministic take-20 (head) operation on a block of text and want a local, network-free transformation with no external dependencies. Prefer the free sandbox endpoint /v1/sandbox/lines-take-20 first; use this paid endpoint when the sandbox is unavailable or rate-limited.
Side effects
- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Malformed JSON body results in a 400 error
- Payment failure or insufficient USDC balance returns a 402 error
