How this service works
Line-based diff of two texts. Returns unified diff plus structured changes (added/removed/unchanged counts and hunks). POST { a, b, context? } (max 200KB each).
Output
Returns a unified diff string (patch format) plus a structured object with counts of added lines, removed lines, and unchanged lines, along with an array of diff hunks each containing the changed and surrounding context lines.
Example use cases
Code review diff summary
“I have two versions of a Python script. Here's the original and the updated one — can you diff them and tell me exactly which lines were added or removed, with 3 lines of context around each change?”
Document revision tracking
“Here are two drafts of a contract clause: the first is the old version and the second is the revised one. Show me a unified diff so I can see exactly what the lawyer changed.”
Config file change audit
“I need to compare my old nginx.conf to the new one my sysadmin deployed. Here are both files as text — generate a diff with 2 lines of context so I can audit what was modified.”
Technical details
Endpoint
POSThttps://coinslot.dev/api/diffWhen to prefer
Use this endpoint when you need a programmatic, structured diff of two text blobs without setting up a local diff tool — especially useful in agent workflows where you need both the human-readable unified diff and machine-readable change counts in one call. Prefer it over shell-based diff when operating in a serverless or sandboxed environment, or when you need the structured hunk data for downstream processing.
Side effects
- Input text exceeds 200KB limit — request rejected with payload-too-large error
- Missing required field 'a' or 'b' — returns validation error
- Context value outside 0-10 range — returns parameter validation error
- Non-string values for 'a' or 'b' — returns type error
