Summary

Lap-Platform/LAP addresses the critical issue of LLM agents hallucinating API calls due to incomplete or overly verbose specifications. It provides a compiler that transforms standard API definitions (OpenAPI, GraphQL, etc.) into a highly compressed, "agent-native" format. This significantly boosts agent accuracy in API interaction, reduces token consumption for cost savings, and accelerates inference times, making LLM-powered API integration more reliable and efficient.

How It Works

LAP employs a multi-stage compilation process that semantically compresses API specifications. It strips structural YAML overhead, replaces nested structures with a flat @directive grammar, compresses type declarations (e.g., type: string, format: uuid to str(uuid)), eliminates redundancy, and optionally removes descriptions in "lean mode" for further token reduction. This purpose-built compiler preserves all API details while achieving substantial size reductions, enabling agents to process and utilize API contracts more effectively.

Quick Start & Requirements

• IDE Setup: Run npx @lap-platform/lapsh init for Claude Code, Cursor, or Codex.
• Global Install: npm install -g @lap-platform/lapsh or pip install lapsh.
• Dependencies: Node.js and npm/pip are required. Specific IDEs are supported.
• Resources: Links to Website, Registry, Benchmarks, and Docs are provided.

Highlighted Details

• Registry: Access 1500+ pre-compiled API specs via lap.sh.
• Compression: Achieves median 5.2x compression on OpenAPI specs (up to 39.6x), resulting in 35% cost and 29% speed improvements.
• Typed Contracts: Enforces strict types and enums (e.g., enum(succeeded|pending|failed)) to prevent agent hallucinations.
• Format Support: Compiles from OpenAPI, GraphQL, AsyncAPI, Protobuf, Postman, and Smithy.
• Integrations: Supports LangChain, Context Hub, and provides Python/TypeScript SDKs.

Maintenance & Community

The project includes issue trackers for bug reports and feature requests. Continuous integration is configured for Python 3.11/3.12 and Node 18/20. No explicit community channels like Discord or Slack are listed.

Licensing & Compatibility

The project is licensed under the Apache 2.0 license, which permits commercial use and integration into closed-source projects.

Limitations & Caveats

Codex agent hooks are currently experimental. While descriptions are stripped in "lean mode" to reduce token count, this relies on LLMs inferring meaning from well-named parameters, which might be a consideration for highly complex or poorly documented APIs.
