# `PhoenixAI.Store.CostTracking.PricingProvider.Static`
[🔗](https://github.com/franciscpd/phoenix-ai-store/blob/v0.1.0/lib/phoenix_ai/store/cost_tracking/pricing_provider/static.ex#L1)

Default pricing provider that reads from application config.

Expects `:phoenix_ai_store, :pricing` to be a map with
`{provider_atom, model_string}` tuple keys and `{input_string, output_string}`
values. Strings are parsed to `Decimal` at lookup time.

## Example config

    config :phoenix_ai_store, :pricing, %{
      {:openai, "gpt-4o"} => {"0.0000025", "0.00001"},
      {:anthropic, "claude-sonnet-4-20250514"} => {"0.000003", "0.000015"}
    }
