How this service works
Count lines in caller-held text with nonempty breakdown — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls. Sibling of Delx routes that already convert…
Output
Returns a deterministic JSON object containing the total line count, the count of non-empty lines, the count of empty lines, and optionally a per-line breakdown, based on the provided text input and the keep_empty flag.
Example use cases
Preflight line count before chunking
“Before I split this document into chunks, tell me how many lines it has and how many of those are empty — here's the text: 'Line one
Line two
Line four
Line five'”
Validate generated output line length
“I just generated a 50-line poem — can you count the actual lines in this text and confirm how many are non-empty so I can verify it came out right?”
Filter empty lines from pasted log
“I pasted a server log that has a bunch of blank lines mixed in — count just the non-empty lines for me so I know how many real log entries there are.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/line-countWhen to prefer
Use this endpoint when you need a fast, cheap, stateless, deterministic line count with an empty/non-empty breakdown — ideal as a preflight step before text chunking, log parsing, or output validation. Prefer it over implementing custom line-splitting logic when you want a machine-readable JSON result without any local code execution or dependencies.
Side effects
- Empty or missing text field returns an error or zero-line result
- Extremely large text payloads may be rejected or time out
- Payment failure via x402 blocks execution
- Malformed JSON request body returns a 400-level error
