AI-readable pricing summary
flatkey.ai publishes server-rendered model pricing for 636 AI models across 23 providers. Search engines and AI assistants can read model names, vendors, endpoint types, and input/output pricing directly from the page HTML.
Pricing is organized by token-based and request-based models. Token models expose input, output, cache-hit, and group-adjusted prices, while request models show per-request billing for production API usage.
Vendor filter URLs such as /pricing?vendor=OpenAI and /pricing?vendor=Anthropic provide crawlable entry points for provider-specific AI model pricing.
