## 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 stableproducts-channel3-price-tracking-stop-14e0e72d -d '<json body>'
```

Example prompt: Stop price tracking for the Channel3 product with ID 'prod-abc123' — I no longer need to monitor its price.

## When to prefer this

Use this endpoint when you need to programmatically stop an active price tracking subscription for a specific Channel3 product by its canonical product ID. Prefer this over simply ignoring tracking results when you want to reduce costs, clean up stale monitors, or free resources after a product has been purchased or discontinued.

## Known failure modes

- Product ID not found — returns 404 or error indicating no such product exists in Channel3
- No active price tracking exists for the product — may return an error or no-op confirmation
- Invalid or missing canonical_product_id — returns validation error
- Payment failure via x402 — tracking stop not processed if $0.01 USDC payment cannot be confirmed
- Service unavailable — 500 or timeout if Channel3 backend is unreachable

## How this service works

Product catalog APIs powered by x402.

## Output

A confirmation that price tracking has been stopped for the specified product, along with the tracking status and optionally the raw response payload if include_raw is set to true.
