costOptimization:
  - recommendation: Cache API responses server-side
    description: >
      ExchangeRate-API terms allow caching. Store exchange rate responses in your
      backend and serve from cache to reduce API calls. Free plan data updates
      once daily so a single request per day is sufficient for most use cases.
  - recommendation: Use the Open Access endpoint for prototyping
    description: >
      The no-key Open Access endpoint at open.er-api.com is free with attribution
      and requires no account, ideal for development and low-volume personal projects.
  - recommendation: Match plan to actual update frequency needs
    description: >
      Free plan rates update daily. If your application does not need sub-hourly
      rate precision, the Free or Pro plan avoids overpaying for Business-tier
      5-minute updates.
  - recommendation: Choose annual billing for paid plans
    description: >
      Annual billing for the Pro plan ($100/yr) saves roughly $20 compared to
      monthly ($10 x 12 = $120/yr), and Business ($300/yr) saves $60 annually.
  - recommendation: Monitor quota via the API Request Quota endpoint
    description: >
      Pro and higher plans have access to the /quota endpoint which returns
      remaining requests for the current billing period, allowing proactive
      monitoring before quotas are exhausted.
