How this service works
Line-level text diff for $0.002 USDC for $0.002 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns a structured line-level diff indicating which lines were added, removed, or unchanged between the original and modified text, typically including hunk information and per-line change markers.
Example use cases
Review config file changes
“Can you do a line-level diff between my old nginx config and the new one I just edited? Old: 'worker_processes 1;
events { }
http { listen 80; }' and new: 'worker_processes 4;
events { }
http { listen 443; }'”
Proofread document revision
“I have two drafts of a paragraph — show me exactly which lines changed. Original: 'The project launched in 2023.
It exceeded expectations.
The team celebrated.' Revised: 'The project launched in 2024.
It exceeded all expectations.
The team celebrated.'”
Detect changelog between code versions
“Compare these two versions of my Python function line by line and tell me what changed: original is 'def add(a, b):
return a + b' and the new version is 'def add(a, b, c=0):
return a + b + c'”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/diff-lines?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, fast, programmatic line-level diff between two text strings without setting up a local diffing library. Ideal for agents comparing document versions, detecting content changes, or surfacing edits in a structured format — especially in lightweight pipelines where installing diff tooling is not feasible. At $0.001 USDC it is cost-effective for high-frequency comparison tasks.
Side effects
- Missing or empty input text fields returns a 400 error
- Extremely large text inputs may be rejected or time out
- Payment failure via x402 protocol returns a 402 Payment Required response
- Malformed request body returns a validation error
- Both texts identical returns an empty diff with no changes
