How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
A JSON object containing a 'diff' array describing each change (additions, deletions, unchanged segments) between the two texts, plus a 'summary' object with aggregate statistics about the changes such as lines added, lines removed, or similarity metrics.
Example use cases
Contract clause change detection
“I have two versions of a legal clause — the original says 'Liability is limited to direct damages only' and the revised version says 'Liability is limited to direct and indirect damages, capped at $10,000.' Can you diff them and show me exactly what was added or changed?”
Code comment review diff
“Can you compare these two versions of my README section and tell me what changed? Original: 'Run npm install to get started.' New version: 'Run npm install, then copy .env.example to .env and fill in your credentials to get started.'”
Policy update audit
“Our privacy policy was updated — original text: 'We share data with third parties for marketing.' New text: 'We do not share data with third parties for any purpose.' Show me the diff so I can flag the key changes.”
Technical details
Endpoint
GEThttps://klymax402.com/api/diff-checker/api/diffWhen to prefer
Choose this endpoint when you need a structured, machine-readable diff between two text strings without standing up your own diff library or tooling. Ideal for agents that need to programmatically detect what changed in documents, configs, policies, or code comments at low cost ($0.005/call) without managing API keys.
Side effects
- Missing text1 or text2 parameter — request may return an error or empty diff
- Extremely large texts may cause timeouts or truncated results
- Identical texts return an empty diff array with a summary indicating no changes
- Non-UTF8 or binary content may produce unexpected diff results
