# DDG Text Diff Service

> DDG Text Diff Service is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Computes and returns the diff (differences) between two text inputs as a bounded, machine-payable artifact

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 ddg-text-diff-service-74e6c54b -d '<json body>'
```

Example prompt: Can you diff these two paragraphs for me and show what changed — here's the original: 'The quick brown fox jumps over the lazy dog.' and the new version: 'The quick brown fox leaped over the sleeping dog.'

## When to prefer this

Choose this endpoint when you need a lightweight, per-call paid text diff computation without managing your own diffing infrastructure, especially in agentic workflows that support x402 micropayments in USDC. It is well-suited for comparing discrete text artifacts (documents, code snippets, paragraphs) on a pay-per-use basis rather than running a persistent diff service.

## Known failure modes

- Missing required 'input' or 'output' fields returns a validation error
- Payment not provided or insufficient USDC balance results in HTTP 402 payment required
- Malformed JSON body causes a 400 Bad Request
- Unsupported bodyType enum value rejected with validation error
- Network timeout if payload is excessively large
- x402 payment rail misconfiguration may cause payment verification failure

## How this service works

Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.

## Output

Returns a JSON object with an 'ok' boolean and the computed diff result showing differences between the two input texts, including additions, deletions, and unchanged regions
