How this service works
Return a deterministic line-by-line difference summary for two texts.
Output
The endpoint returns a structured diff showing which lines or segments were added, removed, or unchanged between the 'before' and 'after' text inputs, enabling precise change detection between two versions of any text.
Example use cases
Config file change review
“I updated my nginx config and want to know exactly what lines changed — before it had 'worker_processes 2; keepalive_timeout 65;' and now it has 'worker_processes 4; keepalive_timeout 30; gzip on;'. Can you show me the diff?”
Draft document revision tracking
“I revised a paragraph in my report — the original was 'Sales grew 10% in Q3 due to new product launches.' and the new version is 'Sales grew 14% in Q3 and Q4 combined, driven by new product launches and expanded distribution.' What exactly changed?”
Automated changelog generation
“Compare these two versions of my API description and tell me what was added or removed: old version is 'Returns user profile data including name and email.' and new version is 'Returns user profile data including name, email, phone, and avatar URL.'”
Technical details
Endpoint
POSThttps://api.agent-payload-tools.workers.dev/text-diffWhen to prefer
Choose this endpoint when you need a deterministic, programmatic text diff within an AI agent workflow — especially when comparing configuration files, document revisions, code snippets, or any string content where exact line-by-line change detection is required. Prefer it over manual string comparison or LLM-based summarization when you need precise, structured diff output rather than a prose description of changes.
Side effects
- Missing 'before' or 'after' fields returns a validation error
- Extremely large text inputs may time out or exceed payload limits
- Payment failure (x402) prevents processing
- Non-string values in before/after fields may cause errors
