How this service works
Web search built for AI agents. Search the live web, pull recent news, and read any page as clean markdown — pay per call, free tier to start.
Output
A structured diff showing what text was added, removed, or modified between the original string (a) and the changed string (b), likely as a patch, line-by-line comparison, or annotated change set.
Example use cases
Example prompt
“Show me exactly what changed between these two versions of the paragraph — original: 'The quick brown fox jumps over the lazy dog.' and revised: 'The quick red fox leaped over the sleeping dog.'”
Technical details
Endpoint
GEThttps://superhighway.walls.sh/diff?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call text diff computation without setting up a diffing library locally, or when operating in an agent context where you need to compare two text blobs on the fly. Ideal for lightweight comparisons of document revisions, config changes, or any two strings.
Side effects
- Missing required parameter 'a' or 'b' returns a validation error
- Extremely large text inputs may timeout or exceed size limits
- Empty strings for both inputs may return an empty diff
- Payment failure (x402) if USDC balance is insufficient
