Overview ¶
Package exchangerate is the library behind the exchangerate command line: the HTTP client, request shaping, and the typed data models for the ExchangeRate-API open tier at open.er-api.com.
No API key required. The client sets a real User-Agent, paces requests, and retries transient failures (429 and 5xx) with exponential backoff.
