A versioned research release containing normalized OpenAI and Anthropic API price records, source identifiers, methodology, machine-readable metadata, and a reusable provider-level chart bundle.
Methodology
Preserves the source refresh as supplied and documents row-level variables and official-source capture lineage.
Population: The 212 normalized price records in the focused nine-offering OpenAI and Anthropic refresh.
Uncertainty: The migration does not rerun source acquisition; it inherits the source package timestamps, scope, and documented limitations.
Limitations
- Not a market census
- Prices and product terms can change
