Prism WASM Integration Guide

Prism is an LLM protocol conversion engine. It converts between provider formats (OpenAI, Anthropic, Gemini, Azure, Vertex, vLLM) via a neutral intermediate representation called Lucent IR. The WASM build exposes 15 pure functions — all String → String, no state, no side effects — making it safe and easy to embed in any language.

Architecture Overview

Your App  ──String JSON──▸  prism.wasm  ──String JSON──▸  Your App
              (provider       (convert via         (provider
               format A)       Lucent IR)           format B)

Two usage patterns:

1. SDK mode — your app speaks one provider format, Prism encodes/decodes for you
2. Transit mode — convert provider A's format directly to provider B's format in one call
