How this service works
Pay USDC, get instant AI summaries, action item extraction, and simplified explanations of any document or text.
Output
Returns an AI-generated comparison of the two submitted documents, including a summary of differences and similarities, notable changes, action items or points requiring attention, and a simplified explanation of how the documents relate to each other.
Example use cases
Contract version comparison
“I have two versions of a vendor agreement — the original and the revised draft they sent back. Can you compare them and tell me what changed, what was removed, and flag any clauses I should be concerned about?”
Research paper similarity check
“Compare these two research papers for me — I want to know how much overlap there is in their findings and methodology, and where they contradict each other.”
Policy document update review
“Our company updated its privacy policy. Can you compare the old version with the new one and give me a plain-English summary of what actually changed and what the impact might be?”
Technical details
Endpoint
POSThttps://briefsnap-x402.fly.dev/api/compare-docsWhen to prefer
Choose this endpoint when you need a direct AI-powered side-by-side comparison of two documents or text bodies, especially when you want differences, similarities, and action items surfaced automatically. Prefer it over generic summarization endpoints when the user specifically wants to understand how two versions or two distinct texts relate to each other. Best suited for contract review, policy change tracking, research comparison, and document diffing workflows where the $3 USDC per-call cost is acceptable for high-quality AI analysis.
Side effects
- Missing or empty document body — returns validation error
- Documents too large or malformed — may result in timeout or truncation
- Payment of $3 USDC not fulfilled — returns 402 Payment Required
- Unsupported body encoding type — returns schema validation error
- Network timeout on the fly.dev host — returns 503 or connection error
