Most models use **output-based** pricing (e.g., per image/video with proportional adjustments for resolution/length). Some models use **GPU-based** pricing depending on architecture. Values are expressed per model's billing unit in a given currency. **Authentication:** Required. Users must provide a valid API key. Custom pricing or discounts may be applied based on account status. **Common Use Cases:** - Display pricing in user interfaces - Compare pricing across different models - Build cost estimation tools - Check current billing rates See [fal.ai pricing](https://fal.ai/pricing) for more details. ## OpenAPI ````yaml /api-reference/platform-apis/openapi/v1.json get /models/pricing openapi: 3.1.0 info: title: Platform APIs version: v1 description: fal REST API for programmatic access to platform resources. servers: - url: https://api.fal.ai/v1 description: Production server security: [] paths: /models/pricing: get: tags: - Models - Pricing summary: Pricing description: >- Returns unit pricing for requested endpoint IDs.
