> ## Documentation Index > Fetch the complete documentation index at: https://docs.trylath.com/llms.txt > Use this file to discover all available pages before exploring further. > ## Agent Instructions > Every Lath operation is POST https://platform.trylath.com/, with a JSON body and `Authorization: Bearer `. `email.send` is POST /email/send. > Branch on `error.code`, never on `error.message`. Every refusal also carries `error.fix`, which names the next step. > Send an `Idempotency-Key` header on any operation that is not retry-safe, so a retry cannot run it twice. > A `lath_test_` key emails only the account's own members and sends no SMS; a `lath_live_` key reaches real recipients and is billed. > The OpenAPI document, generated from the same registry as the routes, is at https://platform.trylath.com/openapi.json. # account.theme.get > Returns the project's theme: the published version hosted pages render, the draft being edited, the effective values with defaults filled in, and `overrides` — only the keys this project has actually set, which is what an editor needs to tell a customisation from a default. ## OpenAPI ````yaml /api-reference/openapi.json post /account/theme/get openapi: 3.1.0 info: title: Lath API version: 0.1.0 description: >- Every operation is one POST.
