## 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 saylor-innovations-guide-library-node-js-memory-leak-heap-debugging-a1c63cf1
```

Example prompt: My Node.js server's memory keeps growing and I can't tell if it's a real leak or just garbage collection — can you pull up the guide on diagnosing and fixing Node.js memory leaks, including how to take and diff heap snapshots?

## When to prefer this

Choose this endpoint when an agent or developer needs a curated, structured written guide specifically about Node.js memory leak detection and heap debugging — rather than general documentation search, LLM-generated advice, or unstructured web scraping. It is well-suited for agents that need authoritative reference content they can relay to a developer, embed in a report, or use as a reasoning scaffold for debugging assistance.

## Known failure modes

- HTTP 402 if payment via x402 is not provided or fails
- HTTP 404 if the guide path is no longer available
- HTTP 500 for server-side errors at the provider
- Empty or malformed JSON body if the guide content is unavailable
- Stale content if the guide has not been updated for newer Node.js versions

## How this service works

Find and fix a Node.js memory leak - tell leaks from normal GC, take heap snapshots, diff them, and fix caches, listeners, closures and timers

## Output

A JSON object containing a guide record with fields: id (unique record identifier), t (title of the guide), c (category), body (full guide text covering how to distinguish leaks from normal GC, take heap snapshots, diff them, and remediate common causes like caches, listeners, closures, and timers), price, and license identifier.
