How this service works
444 endpoints across 9+ chains. Crypto, AI, Social, Finance, Weather, Tools. Pay per call in USDC via x402 with 4 facilitators: Dexter, Meridian, FluxA, GoPlausible.
Output
Returns a structured diff output showing which parts of the text were added, removed, or unchanged between the two input versions, typically as line-level or character-level change annotations.
Example use cases
Reviewing edited contract clauses
“I have two versions of a contract clause — show me exactly what words were added, removed, or changed between the original and the revised version: Original: 'Payment is due within 30 days of invoice.' Revised: 'Payment is due within 15 days of invoice receipt.'”
Tracking code comment changes
“Can you compare these two versions of a Python docstring and highlight what changed? Before: 'Returns the sum of two integers.' After: 'Returns the sum of two non-negative integers, raising ValueError if inputs are negative.'”
Spotting edits in a news article
“I want to see what changed between the original and the updated version of this news paragraph — please diff them and list the additions and deletions clearly.”
Technical details
Endpoint
POSThttps://omni-api-cyan.vercel.app/api/tools/text/diffWhen to prefer
Use this endpoint when you need a quick, paid-per-call text diff via the x402 micropayment protocol without standing up your own diff infrastructure. Best suited for lightweight, on-demand text comparison tasks where integrating a full diff library is not feasible and a simple REST call with USDC payment is preferred.
Side effects
- Missing required 'query' field returns a validation error
- Very large text inputs may cause timeout or truncation
- Identical inputs return an empty or no-change diff result
- Malformed or non-UTF-8 text may cause parsing errors
- API returns generic error object if payment (x402) fails or is insufficient
