Use `by=id` or `by=cfxId` for each reference. Available on all standard plans. ## OpenAPI ````yaml /rapidapi-v1.yaml post /rapid/v1/compare openapi: 3.0.2 info: title: Fexmetrics RapidAPI version: 1.0.0 description: | Customer-facing RapidAPI v1 contract. Raw history returns recorded time-series observations and is restricted by plan depth. Stats, growth, peak-hours, integrity, and compare return derived calculations; access to a derived range does not grant raw observations for that range. `by=id` is the default wherever `by` is available. Use `by=cfxId` when the identifier is a CFX network ID. RapidAPI handles authentication, request limits, quotas, and billing. contact: name: Fexmetrics servers: - url: https://fexmetrics-fivem-redm-server-analytics-api3.p.rapidapi.com description: RapidAPI gateway security: - RapidApiKey: [] tags: - name: Servers description: Public server discovery and current state. - name: Raw History description: Recorded observations with plan-specific download depth. - name: Analytics description: Derived summaries calculated from bounded observation windows. - name: Integrity description: Explainable heuristic analysis; never proof or a calibrated probability. - name: Comparison description: Set-based comparison of two to five public servers. paths: /rapid/v1/compare: post: tags: - Comparison summary: Compare Servers description: >- Compares 2-5 servers over one analytics range.
