Under maintenancePricing
from $3.00 / 1,000 product-checkeds
Monitor product prices and stock on any online shop. Get only what changed: price drops, price increases, back in stock, out of stock and target-price hits. Schedule it, send alerts to Slack, Discord or a webhook, and pay only for products successfully checked.
You can access the Price & Stock Change Monitor – Alerts for Any Product Page programmatically from your own applications by using the Apify API. You can also choose the language preference from below. To use the Apify API, you’ll need an Apify account and your API token, found in API & Integrations in Apify Console.

It simplifies API development, integration, and documentation.
OpenAPI is effective when used with AI agents and GPTs by standardizing how these systems interact with various APIs, for reliable integrations and efficient communication.
By defining machine-readable API specifications, OpenAPI allows AI models like GPTs to understand and use varied data sources, improving accuracy. This accelerates development, reduces errors, and provides context-aware responses, making OpenAPI a core component for AI applications.
