How this service works
Compare two text or HTML snapshots and return additions, removals, and similarity.
Output
A structured response containing the additions (new content in 'after' not present in 'before'), removals (content in 'before' not present in 'after'), and a similarity score reflecting how close the two inputs are.
Example use cases
Monitor competitor website for changes
“Check if this competitor's pricing page has changed since last week — here's the HTML snapshot from 7 days ago and the one I just captured today. Tell me exactly what was added or removed and how similar they still are.”
Track legal document revisions
“I have two versions of our terms of service — the one we published in January and the updated draft from our legal team. Can you compare them and show me every addition and deletion so I know what actually changed before we go live?”
Audit blog post edits before publishing
“Here's the original draft of the blog post and the version my editor sent back. Show me exactly what lines or phrases were added or removed so I can review the changes before I hit publish.”
Technical details
Endpoint
POSThttps://autonomy-api-network.onrender.com/v1/text-diffWhen to prefer
Use this endpoint when you need to programmatically compare two versions of text or HTML content and get structured output identifying exactly what changed — ideal for change detection pipelines, content monitoring, document revision tracking, or auditing webpage updates. Prefer it over manual diffing or generic LLM comparisons when you need precise, structured addition/removal output rather than a prose summary.
Side effects
- Missing 'before' or 'after' field returns a 400 validation error
- Extremely large text payloads may time out or exceed size limits
- Non-UTF-8 encoded content may cause parsing errors
- Payment failure via x402 protocol returns 402 Payment Required
