* fix(agy): say what the model picker is actually waiting on The spinner in the New Session AGY picker read "Checking Antigravity authentication…", but nothing at that point checks authentication — the machine is running `agy models`, and the sign-in prompt is a separate branch below it, shown only when agy reports the failure. Name the wait after the work: "Fetching available models…", the same words agy prints while it fetches. * refactor(agy): describe a probe by its outcome, not by its response The probe function returned a finished `AgyModelsResponse`, so "agy could not be reached" and "agy listed no models" both arrived as a successful response carrying the hardcoded mirror, and the caller could no longer tell which had happened. Every policy decision about that answer has to live inside the probe as a result. Hand back what the probe observed — a live catalog, an auth failure, or nothing usable — and let the caller turn it into a response. Same behaviour: the mirror still stands in for both failure modes, and the 60s cache still holds whatever came out. * fix(agy): serve the model catalog stale-while-revalidate The `agy models` probe is a whole agy invocation — around 3s on a good day, 15s when it times out — and the 60s window meant the New Session picker paid that again a minute after the last look. Keep the last listing agy actually returned and answer from it: fresh for ten minutes, then still answered while a probe refreshes behind it, until the entry is a day old and stops standing in for the machine at all. A probe that times out or loses auth leaves that entry alone, so a blip no longer empties a working picker, and the hardcoded mirror is no longer recorded as if the machine had reported it. Three things fall out of that and are handled here. A machine whose sign-in has actually gone bad would otherwise look healthy for a day, so an auth failure rides along with the catalog it can still serve — and, because nothing else would re-probe a catalog that is still fresh, a warning riding on the answer is itself a reason to look again. A failed probe is not repeated on the very next request either, or a machine where agy hangs would spawn it once per poll. An explicit refresh always costs a probe, and never rides one that was already running when it was asked for. * fix(agy): let Retry force a fresh model catalog probe With the catalog held for ten minutes, Retry would otherwise hand back the answer it was pressed to replace, so the intent travels to the machine: `?refresh=true` on the machine route, an optional RPC param, and a one-shot flag on the query so ordinary mount and focus refetches stay cheap. Every hop is optional, so a hub and a runner on different versions still talk — the older side ignores it and answers from its cache. Retry also has to be reachable, and honest, in the state that needs it. The machine now answers with both a usable catalog and the sign-in failure behind it, so the picker keeps the list and says why it may be out of date, with the button right there rather than only once there is nothing left to show. Pressing it runs agy, which can take tens of seconds, so the button says so while it does. The client contract covers both: `agy-models` is the one catalog route that can carry an `error` on a successful response, and the one that takes a refresh parameter. * fix(agy): use the machine catalog in the in-session model picker New Session already asks the machine what `agy models` lists, but a session that is already open offered the built-in list in `shared/src/models.ts`. That list is a hand-maintained mirror, so a model agy started offering after the last release could be picked for a new session and not for the one already running. Point the composer at the same machine catalog. The mirror stays as the fallback for the moment before the machine answers, and a model the session is already on is kept selectable — and readable, when it is one of the known presets — even after the catalog moves on without it. * fix(agy): announce a model catalog re-check that changed the answer Serving the last known catalog answers the picker instantly, but a picker that was already open kept showing that answer until the user closed and reopened it — the machine had no way to say it had found something newer. Say it on the stream that already carries machine changes. The machine daemon — the only process that answers `<machineId>:listAgyModels` — emits it, and the hub forwards it as `machine-agy-models-updated` with nothing but the machineId. Namespace resolution, per-machine delivery and reconnect replay all come from the existing path. What counts as a change is what the route would answer, not what sits in the cache. That distinction carries the cases: a sign-in that lapsed or came back changes no models yet changes what the user is told; a machine whose agy was signed out has been answering from the hardcoded mirror, and its first real listing is the largest change there is, for every client except the one awaiting it. * fix(agy): re-read the announced machine's model catalog On `machine-agy-models-updated`, cancel and refetch that one machine's catalog query — the app's global connection is always subscribed, so an open picker redraws wherever it is. Cancelling first is what makes it correct rather than merely likely. query-core cancels an in-flight fetch only when the query already holds data, so a picker opening for the first time would otherwise join the request already on its way and settle on the listing the announcement replaced. The refetch is answered from the machine's cache, so it starts no probe and cannot bounce another announcement back. A reconnect the hub could not replay takes the resync path, which clears the agy catalogs the same way — that path has no announcement to fall back on, so it is the one that can least afford to join a stale request. * fix(agy): keep a model the user picked when the catalog moves under them The catalog can now change while the New Session form is open, and the form dropped any selection the machine no longer advertised — including one the user had just made. Keep that one, and list it as no longer listed so the form does not imply agy is still offering it. A model restored from a draft or a saved preference is still dropped: it may never have been runnable here. * fix(agy): announce uncached authentication changes

REST endpoints
Endpoint tables for native clients, grouped by feature. Request/response shapes reference the Zod schemas in shared/src/schemas.ts and shared/src/apiTypes.ts (package @hapi/protocol) — those schemas, not the prose here, are the field-level source of truth. Route behavior is grounded in hub/src/web/routes/*.ts; web/src/api/client.ts is the reference consumer.
Conventions
- All paths below are relative to the hub base URL. Everything under
/apirequiresAuthorization: Bearer <JWT>(Auth). - Path params (
:id,:messageId, …) must be URL-encoded (the web client usesencodeURIComponentthroughout). - Request bodies are JSON (
content-type: application/json) with one exception:POST /api/voice/transcriptionismultipart/form-data. Responses are JSON unless noted (generated images and scratchlist attachments return raw bytes). - Bodies are validated with Zod; failures return
400(see Errors). - gzip: the hub gzips
/api/*JSON responses whenAccept-Encodingaccepts gzip. Negotiation is q-value aware (acceptsGzipinhub/src/web/sseCompression.ts):gzip;q=0is honored as a refusal,*counts unless agzipentry overrides it. Send a normalAccept-Encoding: gzipand decompress transparently. The SSE stream is gzip-compressed separately with per-event flush — see SSE. Source:hub/src/web/server.ts. - Several endpoints are RPC-wrapped: the hub forwards to the session's CLI process over Socket.IO and relays the result. These can fail with HTTP 200 +
{success: false, error}or with 503 — see Errors.

::: warning resume / reopen may return a different sessionId
Both endpoints return the id of the session that now carries the conversation — which may differ from the id you called them on (fresh spawn under a new id; the old row is superseded). Clients must migrate composer drafts and replace navigation to the returned id. Reference: web/src/routes/sessions/followSupersedingSession.ts; the durable link also appears as metadata.supersededBySessionId on the old session.
:::
Optional for v1 (endpoints exist; the v1 native scope does not require them): POST /api/sessions/:id/fork {messageLocalId?} → {sessionId}, POST /api/sessions/:id/rewind {messageLocalId} → {success: true}, GET /api/sessions/:id/export (413 when too large).
Messages
Source: hub/src/web/routes/messages.ts; schemas MessagesQuerySchema, SendMessageRequestSchema, QueuedStateRequestSchema (shared/src/apiTypes.ts), responses CancelMessageResponseSchema, SteerQueuedMessageResponseSchema (shared/src/schemas.ts). Unknown steer delivery is durable and user-resolvable; native clients must implement the same transitions.
| Method & path | Request | Response |
|---|---|---|
GET /api/sessions/:id/messages |
Query: limit? (1–200, default 50), cursor pairs beforeSeq+beforeAt | afterSeq+afterAt (+ optional untilSeq+untilAt, epoch with after) |
MessagesResponse {messages: DecryptedMessage[], page: {direction, limit, epoch, reset, nextBefore*/nextAfter*, snapshotHead*, hasMore}} — full cursor semantics in Pagination |

POST /api/sessions/:id/messages/queued-state |
{localIds: string[]} (≤ 1000, deduped) |
{queuedLocalIds: string[], invokedLocalMessages: [{localId, invokedAt}]} — resync optimistic sends after reconnect |
The hub stamps sentFrom: 'webapp' on REST-sent messages server-side; the request body has no such field.
Permissions
Source: hub/src/web/routes/permissions.ts. Pending requests are not messages: they live in session.agentState.requests (keyed by request id) and move to agentState.completedRequests when resolved — schemas AgentStateRequestSchema / AgentStateCompletedRequestSchema in shared/src/schemas.ts.
| Method & path | Request | Response |

Both routes 404 withRequest not foundif the id is not currently pending, and 409session_inactivewhen the session is inactive.
Session config — mode / model / effort (per flavor)
Source: hub/src/web/routes/sessions.ts; flavor gates in shared/src/modes.ts (getPermissionModesForFlavor) and shared/src/flavors.ts (supportsModelChange, supportsEffort). Wrong-flavor calls return 400; several are additionally rejected with 409 when the session is terminal-controlled (agentState.controlledByUser === true).

GET /api/machines/:id/opencode-models?cwd=, /grok-models?cwd=, /copilot-models?cwd= |
cwd query required (400 without) |
Machines & spawning
Source: hub/src/web/routes/machines.ts; schemas SpawnSessionRequestSchema, MachineListDirectoryRequestSchema, MachinePathsExistsRequestSchema, RenameMachineRequestSchema (shared/src/apiTypes.ts), MachineSchema (shared/src/schemas.ts).
| Method & path | Request | Response |
|---|---|---|
GET /api/machines |
— | {machines: Machine[]} (online machines in the caller's namespace) |
PATCH /api/machines/:id |
{displayName} (trimmed; ≤ 64 chars; empty clears back to hostname) |
{ok: true} |
GET /api/machines/:id/agent-availability |
— | {agents: {agent, available, reason?: 'not_found'|'invalid_configuration'}[]}; 409 runner_upgrade_required on old runners |
POST /api/machines/:id/spawn |

{type: 'success', sessionId} | {type: 'error', message, code?, agent?} (agy accepts only remote) |
POST /api/machines/:id/list-directory |
{path, includeHidden?} |
{success, entries?: (DirectoryEntry & {isGitRepo?})[], error?} |
POST /api/machines/:id/paths/exists |
{paths: string[]} (≤ 1000) |
{exists: Record<string, boolean>, outsideWorkspaceRoots?: string[]} |
POST /api/machines/:id/restart-runner |
{} |
{message}; errors carry code: 'machine_not_found' | 'machine_offline' |
Note the spawn response is discriminated on type, not HTTP status — a failed
spawn is still HTTP 200. Stable spawn failure codes are
agent_unavailable, runner_upgrade_required, and
outside_workspace_roots. Clients should fetch Agent availability when the
machine is selected and use that result to drive the form. The runner performs
the authoritative availability check as part of spawning, covering changes
after the form-level query without requiring a duplicate client RPC.
Availability checks executables and static runner configuration only; it does
not execute the Agent or verify account/login state.
Git & files (RPC-wrapped)
Source: hub/src/web/routes/git.ts. Git endpoints return the raw command output — GitCommandResponse {success, stdout?, stderr?, exitCode?, error?} — and the client parses stdout itself (reference parsers: web/src/lib/gitParsers.ts).
| Method & path | Request | Response |
|---|---|---|
GET /api/sessions/:id/git-status |
— | GitCommandResponse (raw git status stdout) |
GET /api/sessions/:id/git-diff-numstat |
Query: staged=true|false |
GitCommandResponse (raw git diff --numstat stdout) |
GET /api/sessions/:id/git-diff-file |
Query: path (required), staged? |
GitCommandResponse (raw unified diff) |
GET /api/sessions/:id/file |
Query: path (required) |
{success, content?, size?, modified?, error?} — content is base64 (decode before display; web ref: web/src/routes/sessions/file.tsx) |
GET /api/sessions/:id/files |
Query: query?, limit? (1–500, default 200) |
{success, files: [{fileName, filePath, fullPath, fileType: 'file', size?, modified?}]} (ripgrep-backed search) |
GET /api/sessions/:id/directory |
Query: path? (empty = session root) |
{success, entries?: [{name, type: 'file'|'directory'|'other', size?, modified?}], error?} |
When the session has no metadata.path yet, these return HTTP 200 {success: false, error: 'Session path not available'}.
Generated images
Source: hub/src/web/routes/git.ts (same file).
| Method & path | Response |
|---|---|
GET /api/sessions/:id/generated-images/:imageId |
Raw bytes with Content-Type, Content-Disposition, ETag: "<imageId>", Cache-Control: private, max-age=31536000, immutable; 404 JSON when missing |
The image id is an immutable content fingerprint, so it doubles as the ETag: send If-None-Match and the hub answers 304 without the CLI round-trip. Cache aggressively (iOS: URLCache honors this automatically; Android: OkHttp cache).
Uploads (message attachments)
Source: hub/src/web/routes/sessions.ts (UploadFileRequestSchema).
| Method & path | Request | Response |
|---|---|---|
POST /api/sessions/:id/upload |
JSON {filename, content, mimeType} — content is base64; decoded size limit 50 MB → 413 |
{success, path?, error?} — pass the resulting metadata in attachments of send-message |
POST /api/sessions/:id/upload/delete |
{path} |
{success, error?} |
Uploads are JSON+base64, not multipart. Both require an active session.
Scratchlist
Source: hub/src/web/routes/sessions.ts (scratchlist section); schemas ScratchlistEntryCreateRequestSchema, ScratchlistEntryUpdateRequestSchema, caps SCRATCHLIST_MAX_ENTRIES = 200, SCRATCHLIST_MAX_TEXT_LENGTH = 10000 (shared/src/apiTypes.ts).
| Method & path | Request | Response |
|---|---|---|
GET /api/sessions/:id/scratchlist |
— | {entries: ScratchlistEntry[]} ({entryId, text, createdAt, updatedAt, attachments[]}) |
POST /api/sessions/:id/scratchlist |
{text, entryId?, createdAt?, attachments?} (text ≤ 10 000; text or attachments required) |
201 {entry}; 200 {entry} when entryId already exists (idempotent retry); 409 code: 'scratchlist_at_cap' at 200 entries |
PUT /api/sessions/:id/scratchlist/:entryId |
{text?, attachments?} (at least one) |
{entry} |
DELETE /api/sessions/:id/scratchlist/:entryId |
— | {ok: true} |
GET /api/sessions/:id/scratchlist/limits |
— | {limits} (attachment size/count/byte budgets) |
POST /api/sessions/:id/scratchlist/upload |
JSON {filename, content (base64), mimeType} |
{success, attachment}; 413 code: 'scratchlist_attachment_too_large' |
GET /api/sessions/:id/scratchlist/attachments/:attachmentId |
— | Raw bytes (Content-Type from stored metadata) |
DELETE /api/sessions/:id/scratchlist/attachments/:attachmentId |
— | {ok: true}; 409 code: 'scratchlist_attachment_in_use' while referenced by an entry |
Mutations bump scratchlistUpdatedAt in the session's SSE patch — use it as a refetch trigger, not as data.
Voice dictation (the one multipart endpoint)
Source: hub/src/web/routes/voice.ts.
| Method & path | Request | Response |
|---|---|---|
GET /api/voice/transcription/providers |
— | {providers: [{id, label, modes}]} — only providers whose keys are configured on the hub |
POST /api/voice/transcription |
multipart/form-data: file (audio, ≤ 25 MB, audio/* or webm/mp4), provider (openai|elevenlabs|deepgram|groq|openai-compatible), mode = standard, language? (BCP-47-ish, ≤ 35 chars) |
{text, language?}; 413 body too large, 400 bad field |
The realtime-token, voice-assistant token, and WebSocket-proxy endpoints under /api/voice/* belong to the live voice assistant — out of scope for v1.
Usage & storage (owner-only)
Source: hub/src/web/routes/usage.ts, hub/src/web/routes/storage.ts. Both 403 unless namespace is default (Auth → Namespaces).
| Method & path | Request | Response |
|---|---|---|
GET /api/usage/summary |
Query: range=7d|30d|all (default 7d), timeZone (IANA, validated) |
UsageSummaryResponse {range, totals, daily[], byAgent[], byModel[], updatedAt} |
GET /api/storage/sqlite |
— | {path, databaseBytes, walBytes, shmBytes, totalBytes} |
Devices (FCM push)
Source: hub/src/web/routes/devices.ts; full push contract in native-companion-contract.md.
| Method & path | Request | Response |
|---|---|---|
POST /api/devices/register |
{token, platform: 'phone'|'wear', deviceId} (deviceId: any stable 1–128-char install id) |
{ok: true} (upsert) |
DELETE /api/devices/register |
{token} |
{ok: true} |
Visibility
Source: hub/src/web/routes/events.ts (POST /visibility).
| Method & path | Request | Response |
|---|---|---|
POST /api/visibility |
{subscriptionId, visibility: 'visible'|'hidden'} |
{ok: true}; 404 when the SSE subscription is gone |
subscriptionId comes from the SSE connection-changed event (SSE). Report foreground/background transitions so the hub can suppress redundant push notifications while the app is visibly connected.
Hub settings (read)
Source: hub/src/web/routes/hubSettings.ts.
| Method & path | Response |
|---|---|
GET /api/hub-settings |
{sessionSummaryContract: boolean, sessionSummaryInChat: boolean} — readable by any namespace |
SSE
GET /api/events is the realtime channel — subscription params, resume handshake, and reconnect policy are specified in SSE. Its gzip behavior differs from the JSON endpoints (streaming compression with per-event flush), also covered there.
Tier 2 — out of scope for v1
