Technical details
Endpoint
POSThttps://stableproduct.dev/api/channel3/price-tracking/start?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to initiate a new price monitoring subscription for a specific Channel3 product identified by its canonical product ID. Prefer this over listing existing subscriptions (which is a separate endpoint) when the goal is to create, not read, a tracking record. Best suited for agent workflows that automate deal discovery or price-change alerting.
Side effects
- Missing or empty canonical_product_id returns a validation error
- Unknown product ID returns a not-found error
- Payment not processed (x402 payment required) returns a 402 response
- Duplicate subscription may return a conflict error or idempotent confirmation
- Network timeout or service unavailability returns a 5xx error
