## 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`):

## When to prefer this

Choose this endpoint when you need structured, machine-readable patch note data for a specific known patch ID across supported games (WoW, CS2, League of Legends, VALORANT, Deadlock, WARDOGS). Ideal when you already know the patch ID and want granular per-change data including before/after stats, change type labels, and audience context — rather than free-text patch note scraping.

## Known failure modes

- Invalid or unknown patch ID returns an error or empty response
- Patch not yet indexed returns no result
- Malformed patch ID format causes a 4xx error
- Recently published patches may not yet be available if not yet crawled

## How this service works

Every buff, nerf and fix for World of Warcraft: Forever, World of Warcraft (Retail), Counter-Strike 2, League of Legends, VALORANT, Deadlock and WARDOGS.

## Output

Returns a JSON object containing the patch ID, game name, version, publish date, a TL;DR summary, a list of granular changes (each with target, ability, stat, before/after values, category, change type, and source text), and audience-specific notes on who the changes matter to. Also includes links to the original patch page and source URL.
