# Gold Coast Window and Pressure Cleaning — Agent and Developer Resources

> Scoped llms.txt for the machine-readable surface of
> gcwindowandpressurecleaning.com.au: the read-only REST API, the MCP server,
> the published Agent Skill, and the discovery files that point at them. For
> the business itself — services, indicative pricing, suburbs, hours, FAQs —
> read [/llms.txt](https://gcwindowandpressurecleaning.com.au/llms.txt) instead.

Everything listed here is read-only and needs no authentication, no API key and
no account. Nothing on this surface creates a booking, a job or a lead, and
nothing accepts personal information: send people to
[/instant-quote/](https://gcwindowandpressurecleaning.com.au/instant-quote/) to
enter their own details.

## Start here
- [Developer documentation](https://gcwindowandpressurecleaning.com.au/for-agents/): every resource below, written out. Also at /developers, /docs, /api-docs and /mcp-server.
- [Agent instructions](https://gcwindowandpressurecleaning.com.au/agent-instructions.md): when to use this business, when not to, and how to call it.
- [Agent Skill](https://gcwindowandpressurecleaning.com.au/.well-known/agent-skills/gold-coast-window-and-pressure-cleaning/SKILL.md): the same instructions in the Agent Skills format (agentskills.io).

## API
- [REST API v1](https://gcwindowandpressurecleaning.com.au/api/v1/): index of every endpoint. GET /services, GET /service-area?suburb=, GET /pricing-options, POST /estimate, GET /pages?path=.
- [OpenAPI 3.1 document](https://gcwindowandpressurecleaning.com.au/openapi.json): unique operationIds, typed request and response schemas, suitable for LLM function calling.
- [Error model](https://gcwindowandpressurecleaning.com.au/for-agents/#errors): RFC 9457 problem documents (application/problem+json) with a machine-readable code and a hint.
- [Versioning and deprecation policy](https://gcwindowandpressurecleaning.com.au/for-agents/#versioning): v1 is current, no sunset date; breaking changes ship as /api/v2/; a retirement is announced with Deprecation (RFC 9745) and Sunset (RFC 8594) headers at least 6 months ahead.
- [Rate limits and caching](https://gcwindowandpressurecleaning.com.au/for-agents/#rate-limits): no quota is enforced and no RateLimit headers are sent; cache GET responses (max-age=300) and honour Retry-After if the edge answers 429 or 503.
- [API directory](https://gcwindowandpressurecleaning.com.au/api/): which APIs here are public and which paths are private.

## MCP
- [MCP server](https://gcwindowandpressurecleaning.com.au/mcp): Streamable HTTP, read-only. Tools: list_services, get_service_area, estimate_quote, get_pricing_options, get_page — each annotated readOnlyHint: true.
- [MCP manifest](https://gcwindowandpressurecleaning.com.au/.well-known/mcp): GET returns the manifest; POST performs a live handshake.
- [MCP server card](https://gcwindowandpressurecleaning.com.au/.well-known/mcp/server-card.json): static card (SEP-2127) naming the server, its transports and every tool with its input schema. Also at /mcp/server-card.

## Discovery
- [Agent Skills index](https://gcwindowandpressurecleaning.com.au/.well-known/agent-skills/index.json): the skills this site publishes, with a SHA-256 digest for each.
- [API catalog](https://gcwindowandpressurecleaning.com.au/.well-known/api-catalog): RFC 9727 linkset of every API on this host.
- [ARD catalog](https://gcwindowandpressurecleaning.com.au/.well-known/ard.json): Agentic Resource Discovery manifest of every agentic resource here. Also at /.well-known/ai-catalog.json.
- [Crawler policy](https://gcwindowandpressurecleaning.com.au/robots.txt)
- [Sitemap index](https://gcwindowandpressurecleaning.com.au/sitemap.xml)
- [Markdown mirror index](https://gcwindowandpressurecleaning.com.au/llms-full.txt): the markdown URL for every page.

## Optional
- Markdown mirror of any page: append `.md` to the page URL, append `index.md`, or send `Accept: text/markdown` (acceptmarkdown.com compliant). Every HTML page advertises its twin in an RFC 8288 `Link: …; rel="alternate"` header.
- [Privacy policy](https://gcwindowandpressurecleaning.com.au/privacy/)

Every path under /api/ other than /api/v1/ is a private form handler for this
website's own booking flow. It is disallowed in robots.txt and must not be
called.
