Compare Cloud Compute Pricing

compare-compute-pricing

Read-only

Compare cloud compute instance pricing across AWS, Azure, GCP, DigitalOcean, OCI, OVH, and Alibaba. Filter by region, provider, vCPUs, memory, category, processor, or use case. All prices are Linux on-demand list prices in USD. Not every price column is live: provenance.priceTypes says which of each provider's price columns come from a live API, which are static constants, and which are unavailable, and provenance.staticPriceColumns lists the non-live ones outright. When you report a savings plan or reserved rate that appears there, say that it is a static estimate. IMPORTANT: Report all prices EXACTLY as returned. Do NOT add commentary or recommendations beyond the data.

TableJSON Schema

Name	Required	Description
`limit`	No	Max instances to return (default: 20)
`region`	No	Pricing region: us-east, us-west, europe, asia-pacific. Default: us-east
`sortBy`	No	Sort by: price, vcpus, memory, pricePerVCPU. Default: price
`useCase`	No	Use case. Must be one of these exactly (case-insensitive): Web App, Database, HPC, ML & AI, Dev/Test, Big Data. Any other string returns zero matches rather than an error.
`category`	No	Instance category. Must be one of these exactly (case-insensitive): General Purpose, Compute Optimized, Memory Optimized, Storage Optimized, GPU / Accelerated, Burstable. Any other string returns zero matches rather than an error.
`maxVCPUs`	No	Maximum number of vCPUs
`minVCPUs`	No	Minimum number of vCPUs
`provider`	No	Cloud provider. Must be one of these exactly (case-insensitive): AWS, Azure, GCP, DigitalOcean, OCI, OVH, Alibaba. Any other string returns zero matches rather than an error.
`maxMemory`	No	Maximum memory in GiB
`minMemory`	No	Minimum memory in GiB
`processor`	No	Processor. Matched by exact equality (case-insensitive), so a partial value like 'H100' returns nothing. Known values: Intel, AMD, Graviton, Ampere, NVIDIA A100, NVIDIA H100, NVIDIA L4, NVIDIA T4, NVIDIA V100, NVIDIA Other.

TDQS

A4.5/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint and openWorldHint. The description adds critical behavioral details: provenance of price columns, static estimates, and the instruction to avoid commentary. This goes beyond annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise (6 sentences) and well-structured, front-loading the main purpose and then providing important caveats. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 11 parameters with full schema descriptions and an output schema, the description provides sufficient context: scope, filtering, provenance handling, and exact reporting instructions. It is complete for agent use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so parameters are already described. The description adds value by clarifying exact matching behavior for useCase, category, and processor, and noting defaults for region and sortBy.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool compares cloud compute instance pricing across multiple providers and lists them. It distinguishes from sibling tools (e.g., compare-llm-models) which are about LLM models, not compute pricing.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description specifies when to use the tool (comparing compute pricing) and gives behavioral instructions (report prices exactly, mention static estimates). It does not explicitly exclude cases like Windows or spot pricing, but the context of 'Linux on-demand list prices' is clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.7/5.0

Disambiguation5/5

Each tool serves a clearly distinct purpose: cloud compute pricing, LLM catalogue browsing, side-by-side model comparison, custom cost estimation, and model recommendation. The descriptions provide explicit guidance on when to use each tool, eliminating ambiguity.

Naming Consistency5/5

All tool names follow a consistent verb-noun pattern with hyphens (e.g., compare-compute-pricing, estimate-llm-cost). The verbs are imperative and the nouns clearly describe the object, forming a predictable and readable set.

Tool Count5/5

5 tools is well-scoped for the domain of cloud compute and LLM cost comparison. Each tool earns its place by covering a distinct workflow (browsing, comparing specific models, custom costing, recommendation).

Completeness5/5

The tool surface covers the full spectrum of user needs: compute pricing across providers, LLM catalogue exploration, side-by-side comparisons, arbitrary cost estimation, and recommendation with constraints. There are no obvious gaps for the stated purpose of cost analysis.
