How this service works
Call when an agent needs a words diff of two strings. No network. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/diff-words first.
Output
A word-level diff result showing which words were added, removed, or unchanged between the two input strings, computed locally with no external network calls.
Example use cases
Detect edits in revised document
“I have two versions of a paragraph — the original and the edited one. Can you do a word-by-word diff so I can see exactly which words were added, removed, or changed?”
Compare chatbot response versions
“My chatbot gave two different responses to the same question. Compare them word by word so I can see what changed between the first and second version.”
Proofread legal clause changes
“Here are two versions of a contract clause. Can you diff them at the word level so I can quickly spot every word that was altered?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/diff-words?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise word-level diff (as opposed to line-level or character-level) between two strings, and want a deterministic, offline computation at a fixed low cost of $0.01 USDC. Prefer this over the free sandbox endpoint (/v1/sandbox/diff-words) only when the sandbox is unavailable or unsuitable. Use the lines diff or unified diff siblings if line-level or unified patch format output is needed instead.
Side effects
- Input strings exceeding 100,000 characters may be rejected
- Missing 'a' or 'b' fields returns a validation error
- Payment of exactly $0.01 USDC required; incorrect payment amount causes rejection
- Malformed JSON body returns a 400 error
