[Unreleased]

[0.2.0] - 2026-06-08

Added

  • YahooFinanceEx.get_quotes/1 — batched quote fetch for many symbols in one HTTP call. Transparently chunks lists into batches of 50 (Yahoo's per-request ceiling). Returns {:ok, %{symbol => result}} where each result is {:ok, Quote.t()} or {:error, :not_found}.
  • YahooFinanceEx.get_fx_rate/2 — current FX rate between two ISO 4217 currency codes via Yahoo's <FROM><TO>=X quote symbol. Short-circuits identity pairs (get_fx_rate("USD", "USD") returns {:ok, 1.0}) without hitting the API.

Changed

  • Package description tightened to reflect the v0.2 surface.

[0.1.0] - 2026-06-01

Added

  • Initial release: Elixir port of the Ruby yahoo_finance_client gem.
  • YahooFinanceEx.get_quote/1 — fetch a single stock quote via Yahoo's /v7/finance/quote endpoint.
  • YahooFinanceEx.Session GenServer — handles Yahoo's cookie + CSRF crumb auth dance with two fallback strategies (query1, query2). 60-second session TTL with on-demand refresh.
  • YahooFinanceEx.Quote struct — typed result with derived fields (dividend_yield, payout_ratio) computed locally.
  • Test stubbing via Req.Test so consumers can mock Yahoo responses without hitting the network.
