# ICON Aircraft

> ICON Aircraft is an American light-sport aircraft manufacturer in Vacaville, California, maker of
> the amphibious ICON A5. It runs no developer program and publishes no product API. Two
> machine-readable surfaces exist on its own domains and are profiled below: the WordPress REST
> content API behind the corporate website, and the Shopify-hosted Shop ICON merchandise storefront
> — which does expose a live, anonymous Universal Commerce Protocol MCP endpoint.

Generated by the API Evangelist enrichment pipeline on 2026-08-22 from live probes. This file is an
independent third-party profile; it is not published by ICON Aircraft. The provider's own
agent-facing document is /agents.md on the storefront host, saved verbatim in this repository.

## What exists

- [ICON Aircraft Content API](https://www.iconaircraft.com/wp-json/): WordPress 6.7.1 core REST API.
  Anonymous, read-only. 159 posts, 94 pages, 1,709 media items, 5 categories, 38 tags, 242
  searchable items as of 2026-08-22. No credential, no signup, no rate limit published.
- [Shop ICON Storefront API](https://store.iconaircraft.com/agents.md): Shopify storefront JSON.
  Anonymous, read-only. 43 products, 13 collections. Products, variants, collections, predictive
  search, session cart and store metadata.
- [Shop ICON UCP/MCP Server](https://store.iconaircraft.com/api/ucp/mcp): live Model Context
  Protocol endpoint implementing Universal Commerce Protocol 2026-04-08. An anonymous tools/list
  returns 13 tools with full JSON Schema 2020-12 input schemas. This is the only agent-callable
  surface the company exposes.

## What does not exist

- No developer portal, no API reference, no getting-started guide, no API keys, no signup.
- No SDKs, no CLI, no GitHub organization, no packages on npm, PyPI, RubyGems or crates.io.
- No status page, no changelog, no versioning policy, no deprecation policy, no SLA.
- No security.txt, no trust center, no bug bounty, no published certifications.
- No A2A agent card on any host.
- No AsyncAPI, no webhooks, no gRPC, no SOAP.
- No machine-readable representation of the aircraft itself — the A5's configuration, options and
  pricing exist only as prose on the marketing site.

## Specifications in this repository

- [Content API OpenAPI](openapi/icon-aircraft-content-api-openapi.yml): 16 operations, derived from
  the live route index. Read-only subset; write routes and the /wp/v2/users collection are excluded.
- [Storefront API OpenAPI](openapi/icon-aircraft-store-api-openapi.yml): 7 operations, derived from
  the provider's own agents.md and verified by probe.
- [MCP manifest](mcp/icon-aircraft-mcp.yml) and [verbatim tools/list](mcp/icon-aircraft-ucp-mcp-tools.json).
- [Tool crosswalk](mcp/icon-aircraft-tool-crosswalk.yml): 4 of 13 tools have a REST analogue; 9 are
  MCP-only.

## Operating rules an agent must respect

- Checkout requires contemporaneous human approval. The store's own agents.md forbids scripted or
  unattended completion of payment.
- complete_checkout is effectively irreversible through the API. No refund, void or reverse tool
  exists. The only reversal is an out-of-band postal return within 30 days of purchase, per
  https://store.iconaircraft.com/policies/refund-policy.
- complete_checkout requires meta.idempotency-key. No other write tool accepts one, so a retried
  create_cart or create_checkout can duplicate state.
- All MCP prices are integers in ISO 4217 minor units paired with a currency code. Divide by 100
  before quoting USD to a person.
- Every MCP tool requires meta.ucp-agent.profile as a fetchable URI. Omitting it fails discovery
  before dispatch and masks every other error.
- The MCP endpoint is rate-limited per IP with no published quota and no rate-limit headers. Back
  off on 429.
- GET /wp/v2/users on the corporate site returns identifiable staff records anonymously. Do not
  retrieve, quote or store them.

## Corporate context

Founded 2006 by Kirk Hawkins and Steen Strand. A5 production began 2016; FAA type certification in
the primary category was granted in December 2023. The company entered Chapter 11 in 2024 and was
acquired by Shang Gong Group, becoming a sister company of Flight Design in April 2025 — which is
why the Shop ICON storefront also stocks Flight Design branded merchandise.
