aws-bedrock-cost-tool 0.1.0

A CLI tool that reports on the cost per model on AWS Bedrock

aws-bedrock-cost-tool

A CLI tool for analyzing AWS Bedrock model costs using the Cost Explorer API.

Features

• Flexible time periods: days (7d), weeks (2w), months (1m), up to 365 days
• Multiple output formats: JSON, tables, ASCII plots, matplotlib plots (iTerm2), summary
• Three detail levels: basic, standard, full (with regional breakdown)
• Token usage and cache statistics
• AWS profile support
• Importable as Python library

Installation

Requirements: Python 3.14+, AWS CLI configured, uv

git clone https://github.com/dnvriend/aws-bedrock-cost-tool.git
cd aws-bedrock-cost-tool
uv sync
uv build
uv tool install dist/aws_bedrock_cost_tool-0.1.0-py3-none-any.whl

Configuration

AWS Credentials

# Option 1: AWS profile
aws configure --profile my-profile

Cost Explorer must be enabled in AWS Console.

Usage

# JSON output (default), last 30 days
aws-bedrock-cost-tool

# Summary with all models, tokens, and cache stats
aws-bedrock-cost-tool --summary

# Table output
aws-bedrock-cost-tool --table

# Specific period and profile
aws-bedrock-cost-tool --period 7d --profile production

# Time series plot
aws-bedrock-cost-tool --plot-time

# Bar chart by model
aws-bedrock-cost-tool --plot-models

# All visualizations (ASCII)
aws-bedrock-cost-tool --all-visual

# High-quality matplotlib plots (iTerm2 only)
aws-bedrock-cost-tool --plot-image

# Full detail with regional breakdown
aws-bedrock-cost-tool --detail full --table

Output Examples

Summary:

Total: ~$1015.85

Models:
  Claude Sonnet 4.5: ~$962.35 (~24M tokens, cache read: ~1410M tokens, cache write: ~95M tokens)

Library Usage

from aws_bedrock_cost_tool import (
    create_cost_explorer_client,
    query_bedrock_costs,
    analyze_cost_data,
    parse_period,
    calculate_date_range,
    format_date_for_aws,
)

days = parse_period("30d")
