# C's English 語文中心

> Welcome to our site

**When to use this site**

Reach for C's English 語文中心 when a user needs information about this creator's online learning offerings on this specific site. It is the right source for these jobs:

- Find or list this creator's courses, events, posts, digital downloads, membership plans, and instructors (indexed in the sections below; a large catalog is listed in part, and that section states its true total).
- Answer "what is coming up?" — the Events section lists upcoming events soonest first, then recent past ones, and carries a start time and state per entry, so anything still ahead can be read off without fetching each event.
- Search by keyword across courses, events, membership plans, and posts at [https://csenglish.today/search?q=KEYWORD](https://csenglish.today/search?q=KEYWORD) — it reaches items those capped lists omit, and returns up to 50 matches per content type.
- Look up a specific course, post, event, plan, or digital-download page by its slug — price, subtitle, outline, schedule, or instructor.
- Discover every page, including past events and categories, via the [sitemap](https://csenglish.today/sitemap.xml).
- Answer "does this creator teach X?" or "how much is course Y?" for this site.

Do not use it for general web search, other creators' sites, or platform-wide account actions — it only describes the content published on csenglish.today.

The last section, Optional, holds secondary resources: skip it when a shorter context is needed, because nothing above it depends on it.

**How to call it**

- **MCP server** (best for tools/agents): connect to https://csenglish.today/mcp and start with `get_platform_info`, then `search_courses` / `search_posts`, then drill into a slug with `get_course_details`, `get_post_details`, `get_event_details`, or `get_lecturer_profile`. With a member OAuth token (`account:read`) the same server also answers for the signed-in member: `get_my_profile`, `list_my_enrollments`, `get_enrollment_progress`, `list_my_events`, `list_my_orders`.
- **Member API** (signed-in member's own data): POST GraphQL to https://csenglish.today/member/graphql with `Authorization: Bearer` and the `account:read` scope — enrollments with access expiry, last-watched lecture, event registrations, digital products. Those answer what the member has access to, not order records: no order number, coupon code, refund status or invoice. For those, read `viewer.payments` on the same endpoint — the billing history, one node per payment, each with its own `tradeNo`, so a retry is a separate node and nothing joins the attempts of one purchase. `consultingServices` is neither: it lists the services offered against the viewer's courses, and its `meetings` are every undiscarded meeting under the service, booked or not and none of them viewer-scoped; `viewer.consultingMeetings` is the viewer's own bookings and study-group sessions, with a join link on each one that has not ended or been canceled, with `filter: { startedAfter: <unix seconds>, state: ["available", "scheduled"] }` for the upcoming ones. The member notification inbox (`notifications`, `unreadNotificationCount`, `notificationSubscriptions`) is here too, with `markNotificationRead` / `markAllNotificationsRead` / `updateNotificationSubscription` mutations under `account:write`. Obtain the token as described in [auth.md](https://csenglish.today/auth.md).
- **Markdown**: add `.md` to a page path (`/index.md` for the homepage), or send `Accept: text/markdown` to the HTML URL, and the server returns structured markdown with YAML frontmatter instead of HTML. Either signal works on any path below:
  - `/` (homepage)
  - `/faq`
  - `/search?q=:keyword` (searches courses, events, membership plans, and posts, up to 50 matches per type; add `&type=post` to narrow, `&page=2` to paginate)
  - `/courses` (course index, first page only)
  - `/lecturers` (instructor index, first page only)
  - `/@:slug` (instructor profile)
  - `/courses/:slug`
  - `/posts/:slug`
  - `/plans/:slug`
  - `/events/:slug`
  - `/digital-downloads/:slug`
  - `/categories/:slug`
- **HTTP API**: see the OpenAPI spec at [https://csenglish.today/openapi.json](https://csenglish.today/openapi.json).

## Developer & agent resources

- [Developer portal](https://csenglish.today/developer-portal): human-readable hub — OAuth client onboarding (vendor platforms and self-asserted CIMD clients), endpoints, scopes, and links to every resource below.
- [Command-line interface](https://www.npmjs.com/package/loopwise): the `loopwise` CLI for deploying Loopwise Pages and reading this API.
- [MCP server](https://csenglish.today/mcp): Model Context Protocol endpoint for tools and agents. Anonymous tools cover public content; a member OAuth token with `account:read` adds get_my_profile, list_my_enrollments, get_enrollment_progress, list_my_events, and list_my_orders for the signed-in member.
- [MCP server card](https://csenglish.today/.well-known/mcp/server-card.json): discovery metadata for that MCP server.
- [Member API](https://csenglish.today/member/graphql): member-scoped GraphQL (POST, `Authorization: Bearer`) — the signed-in member's own profile, enrollments, progress, event registrations and digital products, plus the notification inbox, read with `account:read`; the notification mark-read and subscription mutations require `account:write`. Those are not order records — no order number, coupon code, refund status or invoice; `viewer.payments` on the same endpoint is the billing history that carries them. `consultingServices` is a catalogue of services offered against the viewer's courses, not a purchase list; `viewer.consultingMeetings` is the member's own bookings and study-group sessions, with a join link on each one that has not ended or been canceled. See the authentication guide for obtaining a token.
