LAPIS
LAPIS (Lightweight API Specification for Intelligent Systems) is a compact, LLM-native API description format authored by Daniel Garcia (cr0hn). It is designed as the format you convert your OpenAPI specifications to when the consumer is a Large Language Model rather than a code generator or human reader. By replacing JSON/YAML structural overhead with a function-signature syntax, indentation-based sections, and centralized definitions for errors, webhooks, rate limits, and workflows, a typical LAPIS document carries the same semantic information as its OpenAPI source while consuming roughly 70-80 percent fewer tokens. LAPIS is not a runtime format and does not replace MCP, function calling, or OpenAPI itself - it is an intermediate representation optimized for AI agents that need to reason about an API inside a constrained context window.

LAPIS Specification
The LAPIS specification defines a token-minimal, LLM-native format for describing HTTP APIs. A LAPIS document is organized into up to seven indentation-based sections - [meta], [types], [ops], [webhooks], [errors], [limits], and [flows] -…
