MeshBay has two HTTP APIs: the **hub's**, for accounts, groups and signaling, and
the **node's control API**, which only its own machine reaches. Files, the index
and chat do not use either: they travel between a client and a node over MNP
(`MESHBAY_NODE_PROTOCOL.md`). Why each API is shaped as it is, who may call
what and what the hub must never see are in `MESHBAY_DESIGN.md`; this file lists
what exists.

`examples/` has small Python programs that use both.

## Hub

Under the hub's address, `https://meshbay.org` on the reference deployment. The
hub also serves the web application at `/` and `/app/`, which are not listed.

| Auth | What the request carries |
|---|---|
| none | No session. Any credential is in the request itself, as the route says |
| user | `Authorization: Bearer`, a person's session. A node's token is refused |
| user or node | A person's session, or a node daemon's token from `/v1/nodes/auth` |
| node | A node daemon's token only |
| moderator | A person's session, for an account with the moderator or admin role |
| admin | A person's session, for an account with the admin role |
| peer hub | Another hub's MHP token. Every route answers 503 unless federation is enabled |

## Node control API

`http://127.0.0.1:<ui_port>`, port 18000 unless `ui_port` in `node.toml` says
otherwise, and never on another address. Every request carries the token the
daemon writes to `<data_dir>/ui-token` (`~/.local/share/meshbay/ui-token` on
Linux), as the `X-MeshBay-Token` header or the `t` query parameter. The daemon
draws a new one at each start and deletes the file when it stops.
