How this service works
Structured diff of two text blocks: per-line additions, deletions and changes, plus an identical flag. Use it to detect whether a contract, policy or spec changed between two fetches.
Output
Returns a structured diff object with per-line entries categorized as additions, deletions, or changes, along with an identical boolean flag indicating whether the two input text blocks are completely unchanged relative to each other.
Example use cases
Contract change detection before signing
“I just refetched our vendor agreement and I want to know if anything changed since last week — show me every line that was added, removed, or modified between the two versions.”
Terms of service monitoring for compliance
“Here are two snapshots of the platform's terms of service from two different dates — diff them and tell me what sections were added or deleted so our legal team knows what to review.”
Spec drift detection in engineering workflow
“We have two versions of an API spec — the one we built against and the one just published by the provider. Can you compare them line by line and flag anything that changed?”

Endpoint
POSThttps://chainverdict.xyz/v1/doc/diffWhen to prefer
Choose this endpoint when you need a structured, machine-readable line-by-line diff of two text documents — especially contracts, policies, specs, or terms — and want explicit addition/deletion/change categorization plus an identical flag, rather than a human-readable summary or a semantic similarity score.
Side effects
- Missing or empty body fields cause a 400 validation error
- Extremely large documents may hit payload size limits
- Non-text binary content passed as input will produce garbled or error output
- Network timeout if the service is temporarily unavailable
- Payment failure if insufficient USDC balance for the $0.002 per-call fee
