@reaatech/otel-cost-exporter-pricing

Status: Pre-1.0 — APIs may change in minor versions. Pin to a specific version in production.

LLM pricing table management with bundled provider data for OpenAI, Anthropic, Google, AWS Bedrock, and Azure. Ships with pre-validated YAML pricing files that are updated on patch releases so your team never has to maintain pricing data.

Installation

npm install @reaatech/otel-cost-exporter-pricing
# or
pnpm add @reaatech/otel-cost-exporter-pricing

Feature Overview

• Bundled pricing — YAML tables for OpenAI (17 models), Anthropic (7), Google (7), AWS Bedrock (14), Azure (9)
• Exact and wildcard matching — getPrice(model, provider) supports exact matches and gpt-4-* style wildcards
• Custom overrides — merge custom YAML pricing files to override or extend bundled tables
• Prompt caching support — tracks cacheReadPrice and cacheCreationPrice for Anthropic models
• Versioned tables — each YAML file carries version and last_updated metadata
• Zod validation — all YAML data is validated at load time against PriceEntryYamlSchema
• Multi-provider merging — loads all bundled tables in parallel and merges provider data, with custom tables taking precedence
• Dual ESM/CJS output — works with import and require

Quick Start

import { loadPricingData, createPricingTable } from "@reaatech/otel-cost-exporter-pricing";
 
// Load all bundled tables
const data = await loadPricingData();
 
console.log(`Loaded ${data.providers.size} providers, version ${data.version}`);
 
// Create the in-memory pricing table
const table = createPricingTable(data);
 
// Look up a model price
const entry = table.getPrice("gpt-4", "openai");
if (entry) {
  console.log(`Input: $${entry.inputTokenPrice}/1M tokens`);
  console.log(`Output: $${entry.outputTokenPrice}/1M tokens`);
}
 
// Check support
console.log(table.supports("openai"));           // true
console.log(table.supports("openai", "gpt-4"));  // true
console.log(table.supports("openai", "gpt-5"));  // false
 
// Total model count
console.log(`${table.modelCount} models tracked`);
