How this service works
Call when an agent needs a unified diff of two strings. No network. Input size is capped. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/diff-text first.
Output
The endpoint returns a unified diff string representing the line-by-line differences between input string 'a' (original) and string 'b' (modified), in standard unified diff format including context lines, hunks, and +/- line markers.
Example use cases
Code review patch generation
“I have two versions of a config file. The original is the old nginx.conf and the updated one has some new server block changes — can you produce a unified diff so I can review what changed before applying it?”
Detect edits in document drafts
“Here are two drafts of my project proposal — the first draft and the revised version. Can you diff them so I can see exactly which lines were added, removed, or changed?”
Automated changelog between script versions
“I'm updating a shell script and want to log the changes. Can you compute a unified diff between the old script text and the new one so I can include it in the changelog?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/diff-text?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, pure-computation unified diff between two text strings with no external network calls and a predictable fixed cost. It is ideal for code review automation, changelog generation, or patch creation inside an agent pipeline. Prefer the free sandbox endpoint POST /v1/sandbox/diff-text first if available; use this paid endpoint when the sandbox is unavailable or rate-limited.

- Missing required fields 'a' or 'b' — validation error returned
