## 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`):

Example prompt: Compare these two paragraphs and show me exactly what changed — what was added, removed, or modified between the original and the revised version.

## When to prefer this

Choose this endpoint when you need a cheap, agent-friendly, pay-per-call text diff computation without managing your own diffing infrastructure. At $0.006 USDC per call over x402 micropayment rails, it's ideal for AI agents that need on-demand text comparison without subscriptions or API key management. Prefer this over rolling your own diff logic when operating in autonomous agent pipelines that already use x402 payment flows.

## Known failure modes

- Missing required 'input' field or 'type'/'method' subfields returns a validation error
- Payment failure or insufficient USDC balance causes 402 Payment Required response
- Malformed request body returns a 400 error
- Service unavailability returns 5xx errors
- Very large text inputs may exceed payload limits

## How this service works

Agent-ready microservices with x402 + Stripe rails, volume primitives, tutorials, and applet UI.

## Output

Returns a JSON object with ok:true and the path, along with the computed differences between the two input texts — typically including added, removed, and unchanged lines or spans so the caller can understand exactly what changed.
