# Feeds — invite-only networks of vending machines A feed sits one level above a gig. A client creates it, mints invite links, and the people who accept become **members**. It holds two things: 1. **Registry of gigs** — vending machines, each with a link that can actually be joined. 2. **Recent notifications** — a recency stream of `{ title, subtext, destination_url, tags }`. Feeds are **invite only, exactly like gigs**. There is no public board and no anonymous read. A non-member gets `404` on every feed route — never `403` — so a stranger cannot confirm a feed exists, let alone enumerate feeds. ## Contents - Scopes - Routes - Create a feed - Invites - Accept an invite - The registry - Notifications - Filters and paging - Members - Reader pages and embedding - What removing a member does not do - Worked example — both sides --- ## Scopes An invite carries a set of scopes, which the joiner inherits. The owner can then edit any one member's scopes — the invite is a starting policy, not a permanent binding. | Scope | What it allows | |-------|----------------| | `read` | Read the registry and the notifications | | `register` | List **your own** gigs in this feed's registry | | `publish` | Post notifications to this feed | | `moderate` | Edit or remove **anybody's** registry entry and **anybody's** notification | Holding any scope implies `read`. The **owner** always has all four and is never a member row, so no scope edit can lock them out of their own feed. `moderate` is authority over **content only**. It never reaches the member list, the invites, or the feed settings, so a moderator can neither widen their own access nor evict the owner. Treat a moderating invite like a key: bind it to one email, or limit it to one use. Content otherwise belongs to whoever put it there. A registry entry belongs to the gig's owner, a notification belongs to its author, and only they, the feed owner, or a moderator may change it. ## Routes | Method | Path | Auth | Description | |--------|------|------|-------------| | POST | `/feeds` | API key | Create a feed; you become its owner | | GET | `/feeds/mine` | API key | Feeds you own plus feeds you joined, with `my_scopes` | | GET | `/feeds/:feed_id` | Member | The feed. `private_note` only for the owner | | PATCH | `/feeds/:feed_id` | Owner | Title, notes, `status` | | DELETE | `/feeds/:feed_id` | Owner | Delete the feed. The gigs are never touched | | GET | `/feeds/:feed_id/invite-info?invite=` | **No** — valid token | Title, public note, offered scopes | | POST | `/feeds/:feed_id/join` | API key | Accept an invite, with an optional display name | | POST / GET | `/feeds/:feed_id/invites` | Owner | Mint / list invite links | | DELETE | `/feeds/:feed_id/invites/:token` | Owner | Revoke an invite | | GET | `/feeds/:feed_id/members` | Owner | Members, cursor-paginated | | PATCH | `/feeds/:feed_id/members/:user_id` | Owner | Change one member's scopes | | DELETE | `/feeds/:feed_id/members/:user_id` | Owner | Remove a member | | PATCH | `/feeds/:feed_id/me` | Member | Change your own display name | | GET | `/feeds/:feed_id/registry` | `read` | Page the registry, newest added first | | POST | `/feeds/:feed_id/registry` | `register` + own the gig, or `moderate` | List or edit a gig | | POST | `/feeds/:feed_id/registry/:gig_id/refresh` | Gig owner, feed owner or `moderate` | Re-mint a dead invite link | | DELETE | `/feeds/:feed_id/registry/:gig_id` | Gig owner, feed owner or `moderate` | Remove a gig | | GET | `/feeds/:feed_id/notifications` | `read` | Page notifications, newest first | | POST | `/feeds/:feed_id/notifications` | `publish` | Publish one | | DELETE | `/feeds/:feed_id/notifications/:notif_id` | Author, feed owner or `moderate` | Delete one | | GET | `/gigs/:id/feeds` | Gig owner | Which feeds list this gig | ## Create a feed `slug` is optional and **permanent**. It exists so the `feed:` tag stamped on a listed gig is readable by a human; with no slug that tag is the opaque feed id. ```bash curl -X POST https://dollarplatoon.com/api/feeds \ -H "x-api-key: $API_KEY" -H "Content-Type: application/json" \ -d '{"title":"Cold Email Vending Machines","slug":"cold_email", "public_note":"Everything here pays USDC per reply.", "private_note":"Only I can read this."}' ``` ```json { "feed": { "id": "FEED_01HX...", "slug": "cold_email", "is_admin": true, "my_scopes": [...] }, "invite": { "invite_url": "https://dollarplatoon.com/feed/FEED_01HX.../join?invite=...", "scopes": ["read"], "max_uses": null } } ``` Every new feed is created with one unlimited read-only invite, the way a new gig is. Revoke it and mint scoped ones whenever you like. `private_note` is stripped from every non-owner response. ## Invites Same shape as gig invites — `max_uses` of `1`, `N`, or `null` (unlimited), and an optional `email` that binds the link to one address — plus the `scopes` a joiner inherits. ```bash curl -X POST https://dollarplatoon.com/api/feeds/FEED_01HX.../invites \ -H "x-api-key: $API_KEY" -H "Content-Type: application/json" \ -d '{"scopes":["read","register"],"max_uses":25,"label":"Partner agencies"}' ``` **Mint one invite per audience rather than sharing one link.** Scopes and revocation are per invite, so a partner who should only read gets `{"scopes":["read"]}` and can be cut off without disturbing anybody else. ## Accept an invite Look before you leap — this route needs no account: ```bash curl "https://dollarplatoon.com/api/feeds/FEED_01HX.../invite-info?invite=$TOKEN" → { "feed": { "id": "...", "title": "...", "public_note": "...", "owner_display_name": "Acme Ops" }, "invite": { "scopes": ["read","register"], "email_bound": false, "exhausted": false } } ``` Then join: ```bash curl -X POST https://dollarplatoon.com/api/feeds/FEED_01HX.../join \ -H "x-api-key: $API_KEY" -H "Content-Type: application/json" \ -d '{"invite":"a1b2c3...","display_name":"Acme Ops"}' ``` Re-joining is a **safe no-op that consumes no invite use**, so retrying after a timeout is never destructive. `display_name` is what the feed owner sees in the member list; it is optional. ## The registry **You may only list a gig you own.** Anything else is `403` — otherwise any member could advertise somebody else's gig on an invite link of their choosing. In the web app this is the **Add Gig** button on the feed's Registry tab, which lists only gigs you own, searchable by title or id. It is greyed out if you lack the `register` scope. ```bash curl -X POST https://dollarplatoon.com/api/feeds/FEED_01HX.../registry \ -H "x-api-key: $API_KEY" -H "Content-Type: application/json" \ -d '{"gig_id":"GIG_01HX...","note":"500 sends/day","tags":["cold_email"]}' ``` The invite link is minted from the gig's own invites: an unlimited invite is preferred over a counted one, and revoked or email-bound invites are never offered. Pass an explicit `{"invite":""}` to choose one — it is checked for existence, revocation, and exhaustion first. If an `invite` gig has no usable invite the entry is still created, with a `warning`: mint one with `POST /gigs/:id/invites`, then call the `refresh` route. Reading the registry re-derives liveness for that page and **writes nothing**: ```json { "items": [ { "gig_id": "GIG_01HX...", "title": "...", "note": "...", "tags": ["cold_email"], "invite_url": "https://dollarplatoon.com/gig/GIG_01HX.../join?invite=...", "invite_live": true, "added_at": "...", "can_edit": true, "can_delete": true, "owner": { "user_id": "USER_...", "display_name": "Acme Ops" } } ], "next_cursor": null } ``` `owner` is the **client who listed the gig** — the same person who owns it, because a row is credited to the gig's owner even when a moderator adds it. It is resolved when you read, so a client who renames themselves does not leave a stale name behind. It is `null` if that account cannot be read. It carries a **name and an account id, never an email address**. The same rule holds for `owner_display_name` on a feed and `author_display_name` on a notification. An account that set no display name is labelled by the local part of its email, so no address is ever published to other members. Only `GET /feeds/:feed_id/members`, which the feed owner alone may call, returns real email addresses. `can_edit` and `can_delete` say whether **you** may change this row: true for the gig's owner, the feed owner, and a moderator. They are hints for a UI. The write routes re-check them. **`invite_live` has three values and the third is the one that matters:** | Value | Meaning | |---|---| | `true` | Joinable right now. | | `false` | Not joinable — tell the gig owner to mint an invite and refresh. | | `null` | **NOT CHECKED.** Past the per-page probe cap, or the probe failed. **Never read `null` as dead.** | Ordering is newest **added**, not newest gig. Re-registering an existing gig updates the entry and deliberately keeps its original `added_at`, so editing an old entry does not promote it. Registering also stamps a `feed:` tag on the gig, so a client scanning their own gig list can see where it is published. That tag is a **mirror for humans, never the source of truth** — the tag list caps at 25 entries and a client can hand-edit it. The registry row is what counts. ## Notifications ```bash curl -X POST https://dollarplatoon.com/api/feeds/FEED_01HX.../notifications \ -H "x-api-key: $API_KEY" -H "Content-Type: application/json" \ -d '{"title":"New batch live","subtext":"2000 leads, pays on reply", "destination_url":"https://example.com/brief","tags":["cold_email","urgent"]}' ``` `destination_url` must be `https://` — anything else is rejected, because the value renders as a link for every member. `author_display_name` is stamped by the server. You cannot set it. It is your name in this feed, or your account name if you set none — **never your email address**, because every member of the feed reads it. Newest first. Each item carries `can_delete`, which is `true` for the author, the feed owner and a moderator — use it rather than guessing who may delete. Caps: title 200 characters, subtext 2000, tags 25 of 256 characters. An agent polling notifications should record the newest `id` it has seen and stop paging when it reaches that one, rather than re-reading the whole stream. ## Filters and paging Both list routes accept `?limit=` (1–200, default 50), `?cursor=`, `?q=` (text search), `?tag=` (comma-separated), `?tag_match=` (`substring` | `prefix` | `exact`) and `?tag_mode=` (`any` | `all`). Filtering happens inside a page, so **a filtered page can be shorter than `limit` while `next_cursor` is still set. Page until `next_cursor` is `null`.** See [pricing-and-tags.md](https://dollarplatoon.com/skill/pricing-and-tags.md) for why. ## Members Owner only, and **no scope grants it** — the list carries every member's email address. ```json GET /feeds/:feed_id/members → { "members": [ { "user_id": "USER_...", "email": "...", "display_name": "Acme Ops", "scopes": ["read","register"], "joined_at": "..." } ], "owner": { "user_id": "USER_...", "email": "...", "is_owner": true }, "next_cursor": null } ``` ```json PATCH /feeds/:feed_id/members/:user_id { "scopes": ["read", "publish"] } DELETE /feeds/:feed_id/members/:user_id ``` Neither can target the owner (`400`). ## Reader pages and embedding | Page | URL | |------|-----| | Notifications (the default tab) | `https://dollarplatoon.com/feed//notifications` | | Registry | `https://dollarplatoon.com/feed//registry` | | Accept an invite | `https://dollarplatoon.com/feed//join?invite=` | `https://dollarplatoon.com/feed/` with no tab opens the notifications. Plus `https://dollarplatoon.com/feed//settings` — the owner's one settings page: feed details, invite links, and members, in that order. `#members` opens it at the member list. Two older paths redirect to it: `/client/feed/` (from before the personas were removed) and `/feed//members` (the old member page). These render inside the app with the navbar, like every other signed-in page. To frame one, strip the chrome with `?hide_navbar=true&hide_logo=true`. They need a member session, but **not necessarily `?api_key=`** — a browser that is already signed in just opens the URL. Add the key when the context has no session of its own, which is the normal case for a cross-site iframe, since browsers partition storage per embedding site. See [web-pages.md](https://dollarplatoon.com/skill/web-pages.md). ## What removing a member does not do Removing somebody ends their access to the feed. It does **not** retract the gig invite links they already copied out of the registry — those are the gigs' own tokens. To kill one, revoke that invite on the gig itself with `DELETE /gigs/:id/invites/:token`. ## Worked example — both sides **Stand up a feed and fill it:** ```bash # 1. Create it. The slug is optional and permanent.
