# Wealth Agent Text Diff

> Wealth Agent Text Diff is a paid API for AI agents from wealth-agent.wealthagent-app.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).

Computes a unified diff between two text strings, returning added/removed line counts and a unified patch format

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability wealth-agent-text-diff-64115b4b
```

Example prompt: Show me the diff between these two texts — original: 'Hello world\nLine two\nLine three' and changed: 'Hello world\nLine two modified\nLine three\nLine four' — tell me how many lines were added and removed and give me the unified patch.

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call line-level text diff without setting up a local diffing library or server. It is ideal for agents that need to detect and summarize textual changes on demand, especially in workflows where computing a unified patch programmatically would require additional dependencies. It suits lightweight comparison tasks on small to medium text snippets.

## Known failure modes

- Missing required query parameters 'a' or 'b' results in an error response
- Payment not fulfilled (x402 protocol) causes a paid_not_delivered status
- Very large text inputs may cause timeout or truncation
- Identical strings return a diff with zero added and zero removed lines
- Non-UTF8 or binary content may produce unexpected diff output

## How this service works

Return the line-level diff between two texts as added/removed/unified hunks with counts. Use it to review a patch, compare two API responses, or decide whether two documents actually differ before spending tokens on them.

## Output

Returns a JSON object with kind set to 'diff', the count of added lines, the count of removed lines, a unified diff string in standard patch format, and the number of hunks.
