otel-cost-exporter · packages

Calculates real-time LLM usage costs by processing OpenTelemetry GenAI semantic convention spans. It provides a `SpanProcessor` for integration into Node.js OTel SDKs or a standalone collector service, using bundled pricing tables to export cost metrics via Prometheus, OTLP, or JSON.

Calculates GenAI token costs in USD by normalizing model names and processing token counts from OpenTelemetry semantic convention spans. It provides a `CostCalculator` class that integrates with a pricing table, an LRU cache, and a model normalizer to handle complex pricing logic like prompt caching and provider-specific model variants.

Provides a command-line interface to manage OTLP-based cost tracking, including running an OTLP collector service, validating pricing table schemas, and generating cost reports from trace data. It serves as the primary utility for configuring and interacting with the otel-cost-exporter ecosystem.

Provides shared TypeScript types, Zod schemas, and GenAI semantic conventions for modeling and validating LLM cost data. It serves as the foundational library for the otel-cost-exporter ecosystem, requiring `zod` and `pino` at runtime.

Provides a lookup interface for LLM token pricing across major providers using bundled, versioned YAML data. It exports functions to load these datasets and instantiate a `PricingTable` object that supports exact and wildcard model matching.
