# CoCo Text Diff

> CoCo Text Diff is a paid API for AI agents from cocoeatsai.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).

Compares two text strings and returns a similarity score, unified diff, and line-change counts

## Facts

- Price: $0.001/call
- Payment: x402

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 coco-text-diff-2023485c
```

Example prompt: Can you diff these two version strings for me — string A is '1.2.3' and string B is '1.3.0' — and tell me the similarity score and what changed?

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.001) programmatic text diff with a similarity score returned as structured JSON — especially useful in agent workflows comparing version strings, config snippets, or short text blocks where a unified diff and numeric similarity are both needed in one call.

## Known failure modes

- Missing required query params 'a' or 'b' — likely returns an error or empty result
- Very large strings may cause performance degradation or timeouts
- Non-UTF8 or binary input strings may produce unexpected diff output
- Payment not completed (x402) results in 402 response before diff is computed

## Output

Returns a JSON object with: a boolean 'identical' flag, a float 'similarity' score between 0 and 1, integer counts for 'lines_added' and 'lines_removed', and a 'unified_diff' string showing the standard unified diff format between the two inputs.
