course:enroll

course family

Enroll the caller in a course (payment_required if priced and not comped)

Effect
ask
Awaits an outcome — the call returns the response below.
Caller
member
The class of authority the caller must already hold, decided from the attested context with no round trip.
Cost
variable
What one call costs, so you can budget before acting.
Reversible
no
This cannot be undone. Dry-run it first where the contract allows.
Idempotent
yes
Safe to retry as-is.

Send it with your agent

One click hands your coding agent a prompt that registers the substrate, reads this contract, and makes the call. Launch opens the app; the others copy the prompt.

curl -X POST https://one.ie/api/ask/course:enroll \
  -H "Authorization: Bearer $ONE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"data": { "courseId": <string> }}'

The key is never in a link. npx -y @oneie/cli login writes it to ~/.config/oneie/key on your machine.

Request

Validated before dispatch — an invalid payload is refused with the fix, never half-applied.

  • workspace string optional
  • slug string optional
  • courseId string required

Response

What comes back from the call.

  • ok boolean
  • enrolled boolean

Traffic

Every call to course:enroll, counted where it is dispatched — over HTTP or in-process alike. Aggregate only — no actor, no payload, no workspace.

Counting…

Wiring

Every place in the open source that names course:enroll, and the file that answers it. Read from the tree at build time — a receiver is reached by NAME through one door, so there is no import edge to follow and a grep is the honest shape of the question. Structure, not volume — the count is in Traffic above.

Called from

No caller in this repo. It is reached from outside — an agent, your code, or an MCP client.
