Machine-readable contracts and guidance for agents and developers working with the public Trelice website.

-   [**Agent instructions** When to use Trelice, what agents can safely read, and when explicit approval is required before submitting data.](/agents.md)
-   [**Agent Skills index** A verifiable Agent Skills discovery index and focused Trelice public-site skill.](/.well-known/agent-skills/index.json)
-   [**ARD manifest** Agentic Resource Discovery entries for the Trelice public API and agent skill.](/.well-known/ard.json)

-   [**LLM site map** Product summary, when-to-use guidance, and links to authoritative Trelice pages and documentation.](/llms.txt)

## Public API scope

The public website API supports read-only NLWeb search plus demo requests and protocol-derived document suggestions. It does not expose protocol authoring, customer data, webhooks, or an MCP server. The two marketing operations are unauthenticated and create a real follow-up or review side effect.

-   [**`GET /ask`** Search authoritative public Trelice pages with an NLWeb response.](/openapi.json)
-   [**`POST /ask`** Search public Trelice pages with an NLWeb query object and optional SSE.](/openapi.json)
-   [**`POST /api/leads`** Request a Trelice demo.](/openapi.json)
-   [**`POST /api/document-suggestions`** Suggest a protocol-derived document.](/openapi.json)

Use the [Trelice OpenAPI specification](/openapi.json) as the authoritative request and response contract.
