How this service works
Call when an agent needs a chars diff of two strings. No network. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/diff-chars first.
Output
Returns a character-level diff showing exactly which characters were added, removed, or changed between the two input strings, computed locally without network access.
Example use cases
Detecting typo in edited text
“I have two versions of a short string — the original is 'color' and the edited one is 'colour'. Can you run a character diff to show exactly what changed?”
Comparing code snippet revisions
“Show me the character-level differences between these two function signatures: 'function calcTotal(price, tax)' and 'function calculateTotal(price, taxRate)'.”
Auditing config value changes
“I need to see exactly which characters changed between these two config strings: 'timeout=30s&retry=3' and 'timeout=60s&retry=5'. Can you diff them?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/diff-chars?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, character-level diff between two strings and want a simple, low-cost ($0.001 USDC) computation. Prefer the free sandbox endpoint POST /v1/sandbox/diff-chars first for testing. Choose this over word-level or line-level diff services when character granularity matters.
Side effects
- Input strings exceeding 100,000 characters each may be rejected
- Missing or malformed 'a' or 'b' fields return a validation error
- Payment of exactly $0.001 USDC required; incorrect payment may cause rejection
