Price Cacher

The Price Cacher service encompasses two major components:

1. A cron job for price data updates
2. A REST API for data retrieval

​

Price Data Update Job

The cron job is responsible for systematically collecting and storing price data from designated sources to a database. It operates on a fixed schedule, running every 5 minutes.

Presently, the assets list (for which we query prices) is principally determined by the assets supported by Aldus. The price data is sourced from the CoinGecko API. The integration of this caching technique significantly mitigates the necessity for direct API calls to fetch price data, thereby reducing associated data consultation costs.

Price Cacher API

The Price Cacher API offers a conduit for accessing the cached price data by third-party clients and services. This system holds the following benefits:

• Ease of Integration: Being a REST-based API, it allows any client that supports HTTP requests to directly access relevant data. It offers a considerably simplified method of interaction compared to direct database engagement.
• Access Control: The API holds configurable access policies, capable of limiting client access or enforcing usage rate limits, thereby procuring a more secure and controlled data access environment.
