lap

A command-line tool for finding, downloading, compiling, and managing API specifications. An API specification is a machine-readable description of how software services can be called, such as OpenAPI, GraphQL, AsyncAPI, Protobuf, or Postman formats.

In plain words
What is it for?
Use it to search an API registry, download or compile specifications, generate agent skills, and publish APIs.
Why use it?
It gives API descriptions a consistent way to be discovered, converted, searched, and published for agent use.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lap scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.

LAP CLI

Compile, search, and manage API specs for AI agents.

Command Resolution

IMPORTANT: Always use curl for registry operations (search, get, check). Do NOT use npx for these -- it downloads the package every time and takes minutes. curl is instant.

# Search the registry
curl -s 'https://registry.lap.sh/v1/search?q=<query>'

# Download a spec
curl -sH 'Accept: text/lap' https://registry.lap.sh/v1/apis/<name> -o <name>.lap

# Get API metadata (version, endpoint count)
curl -sH 'Accept: application/json' https://registry.lap.sh/v1/apis/<name>

Only use the CLI (lapsh or npx @lap-platform/lapsh) for operations that require it: compile, publish, skill-install, init.


Agent Flow -- Consuming APIs

Use this flow when a user needs to find, download, or work with an API.

1. Discover

Option A -- curl (fastest):

curl -s 'https://registry.lap.sh/v1/search?q=<query>'

Option B -- CLI:

lapsh search <query> [--tag <tag>] [--sort relevance|popularity|date] [--limit <n>]

Results show name, endpoint count, compression ratio, and a [skill] marker for installable skills.

2. Acquire

Option A -- curl (fastest):

curl -sH 'Accept: text/lap' https://registry.lap.sh/v1/apis/<name> -o <name>.lap

Option B -- Install a skill (if [skill] marker present):

lapsh skill-install <name> --target codex
# Installs to ~/.codex/skills/<name>/

Option C -- Download via CLI:

lapsh get <name> -o <name>.lap
lapsh get <name> --lean -o <name>.lean.lap

Option D -- Compile a local spec:

lapsh compile <spec-file> -o output.lap
lapsh compile <spec-file> -o output.lean.lap --lean

Supported formats: OpenAPI (YAML/JSON), GraphQL (SDL), AsyncAPI, Protobuf, Postman, Smithy. Format is auto-detected.

3. Use

Once you have a .lap file, read it directly -- LAP is designed for AI consumption. Key markers:

Marker Meaning
@api API name, version, base URL
@endpoint HTTP method + path
@param Parameter (query, path, header)
@body Request body schema
@response Response status + schema
@required Required fields
@error Error response

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

lap is a skill published in the GitHub repository Lap-Platform/LAP (346 stars, last pushed 14d ago), licensed Apache-2.0. It adds 89 tokens to every session and 1,667 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
