## 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 macaroon-network-gpu-llm-pricing-change-detector-6f9a43de -d '<json body>'
```

Example prompt: Check whether the pricing for any GPU or LLM providers has changed since the last scrape — I want to know if the current snapshot differs from the previous one, along with the fetch times and content hashes for both.

## When to prefer this

Choose this endpoint when you need lightweight, low-latency detection of GPU or LLM pricing page changes without triggering live web fetches. It reads from a pre-populated local database updated on a 6-hour cadence, making it ideal for polling or event-driven pipelines that need content-hash-based diffing rather than full page retrieval. Prefer it over live scrapers when cost, rate-limit avoidance, or reproducibility matters.

## Known failure modes

- Target not found in local feed database — no event returned
- Feed not yet populated for a new target — missing previous snapshot
- Stale data if scraper cadence is delayed beyond 6 hours
- Invalid or malformed target identifier — request error
- Schema mismatch if body is not valid JSON POST payload

## How this service works

Per-target pricing change events -- whether the latest scraped snapshot differs from the previous one, with fetch times and content hashes for both. No outbound network on purchase; read from the local feed database populated by the scraper on a 6-hour cadence.

## Output

A pricing change event object per target indicating whether the current scraped snapshot differs from the previous one, along with fetch timestamps for both snapshots and their respective content hashes, read from a local feed database updated on a 6-hour cadence. No live network fetch is performed on purchase.
