Streaming API

Endpoints for live video and audio streaming via Mux, DJ session management, video generation, and streaming webhook processing.

Session lifecycle

A DJ session transitions through several statuses during its lifecycle. The active and live statuses are both treated as current sessions — meaning the session is considered in-progress and occupies a streaming slot for the wallet. Endpoints that check for an existing session, end sessions, or authorize session access treat both statuses uniformly.

Status	Meaning
`active`	Session created, waiting for or receiving an ingest connection
`live`	Mux stream is active and playback is available to listeners
`ended`	Session stopped by the DJ (replay assets deleted)
`archived`	Session stopped by the DJ with replay retention (assets preserved, credits charged)
`auto-ended`	Session expired (exceeded the 2-hour maximum) or cleaned up automatically

List live streams

GET /api/basefm/live

Returns all currently active Mux live streams. No authentication required. The availability field reflects the station state:

live — Mux is healthy and at least one DJ is currently broadcasting.
idle — Mux is healthy but no DJs are live (for example, after the most recent set ended).
degraded — Mux credentials are missing or the Mux API returned an error. The response falls back to cached session data from the database.

When Mux is available, active streams are enriched with metadata from the corresponding DJ session record (matched by stream ID). This means fields like name, wallet, playbackId, and startedAt can resolve from session data even when Mux stream metadata is sparse or missing.

Field	Type	Description
`djs[].id`	string	Mux live stream ID
`djs[].name`	string	DJ display name. Resolved from Mux stream metadata first, then from the DJ session record, and defaults to `Anonymous DJ` if neither is available.
`djs[].wallet`	string \| null	DJ wallet address. Resolved from Mux stream metadata first, then from the DJ session record.
`djs[].playbackId`	string \| null	Mux playback ID. Resolved from the Mux stream first, then from the DJ session record.

`djs[].status`	string	Stream status (`active`)
`djs[].startedAt`	number \| string	ISO 8601 string when a matching DJ session record exists, otherwise a Unix timestamp from the Mux stream. Session-cache entries always return an ISO 8601 string.
`djs[].source`	string	Where the DJ data was resolved from: `mux` (live Mux API) or `session-cache` (database fallback)
`djs[].hlsUrl`	string \| null	HLS playlist URL for playback
`djs[].embedUrl`	string \| null	Embeddable player URL
`count`	number	Number of live DJs
`primaryDj`	object \| null	The first DJ in the list, or `null` when no DJs are live
`availability`	string	Stream availability and data source status. One of `live` (at least one DJ is broadcasting, served from Mux), `idle` (Mux is healthy but no DJ is currently live — for example, after a set ended), or `degraded` (Mux API or credentials are unavailable and the response is served from the session cache).
`distribution`	object	Distribution state for the baseFM station. See distribution for the full shape.
`distribution.origin.status`	string	Origin stream status. `active` (a DJ is broadcasting), `idle` (Mux is healthy but no DJ is live — the normal off-air state), or `degraded` (Mux API or credentials are unavailable).
`distribution.origin.playbackId`	string \| null	Mux playback ID for the origin stream
`distribution.origin.hlsUrl`	string \| null	HLS URL for the origin stream
`distribution.firstParty`	object	Health status of the first-party baseFM page

`distribution.relays`	array	Configured relay destinations and their health
`distribution.requiredRelayStatus`	string	Aggregated status of all required relays
`distribution.overallStatus`	string	Overall distribution health across origin, first-party page, and relays

When the response has "availability": "degraded", it may also include an error field with a human-readable description of why the Mux API could not be reached. An "availability": "idle" response is the normal off-air state and does not include an error field.

Errors

Code	Description
500	Internal error and no cached sessions are available

When Mux credentials are missing or the Mux API is unreachable, the endpoint returns cached live sessions from the database with "availability": "degraded" and HTTP status 200 (as long as cached data exists). A 500 is only returned when both the Mux API and the session cache are unavailable.

Create live stream

POST /api/basefm/streams

Creates a new Mux live stream. Access is granted if the caller meets any of the following conditions:

The wallet holds at least 2,500,000 BASEFM tokens on the Base network, or
The caller has an active community guest pass (available to Builder and Whale tier claimed holders via the community program), or
The caller pays a $5 USDC session fee on Base by including a verifying txHash in the request

Mux live stream creation only arms the stream — it is not actually live until OBS or ffmpeg connects to the RTMP ingest. Use the Stream status endpoint to confirm ingest is up.

The wallet address used for BASEFM token verification must be a Coinbase Smart Wallet on Base. The platform enforces smartWalletOnly as its connector policy — injected wallets (such as MetaMask) are not supported for DJ streaming.

Request body

Field	Type	Required	Description
`wallet`	string	Yes	Wallet address of the DJ. Used for BASEFM token balance verification.
`name`	string	No	DJ display name (default: `DJ`)
`city`	string	No	City or location label for the DJ. Stored in session metadata and displayed on the dashboard. Trimmed and capped at 80 characters.
`txHash`	string	Conditional	Transaction hash for the $5 USDC paid session. Required when the caller does not hold the BASEFM token threshold and does not have a community guest pass. The transfer must be to the platform wallet for the full fee from the request `wallet`.

Response (200) — recovery (existing session)

When the authenticated caller already owns a non-expired current session, the endpoint returns the existing stream control payload instead of creating a duplicate stream. This lets DJs recover after a refresh without losing their controls or accidentally creating a new stream.

  }
}

Field	Type	Description
`success`	boolean	Always `true`
`reconnected`	boolean	Present and `true` only on a recovery response, when the authenticated caller already owns a non-expired current session and is being handed the existing stream controls.
`stream.id`	string	Mux live stream ID
`stream.name`	string	DJ display name
`stream.wallet`	string	Wallet for the session
`stream.streamKey`	string	RTMP stream key
`stream.rtmpUrl`	string	RTMP ingest server URL
`stream.fullRtmpUrl`	string	Full RTMP URL including stream key (for OBS or ffmpeg)
`stream.playbackId`	string \| null	Mux playback ID for viewers
`stream.status`	string	Mux or session status (e.g. `created`, `active`)
`session.id`	number	DJ session record ID
`session.wallet`	string	The wallet address used for the session. When access is granted via a community guest pass, this is the claimed Agentbot wallet (not the wallet sent in the request).
`session.maxDuration`	number	Maximum session duration in seconds (7200 = 2 hours)
`session.remaining`	number	Remaining seconds in the session
`session.expiresAt`	string	ISO 8601 timestamp when the session expires
`session.accessToken`	string	A signed session token that can be used to authenticate subsequent `GET` and `DELETE` requests on this session without requiring a full user session. Valid for the session duration plus a 1-hour grace period.
`ffmpeg.command`	string	Default ffmpeg command (audio-only). Suitable for unattended agent streaming with no video track.
`ffmpeg.audioOnlyCommand`	string	Audio-only ffmpeg command. Encodes a single audio file to the Mux RTMP endpoint.
`ffmpeg.playlistCommand`	string	ffmpeg concat playlist command. Use for DJs who provide an ffmpeg `concat` playlist file.
`ffmpeg.artworkCommand`	string	Artwork-and-video ffmpeg command. Use when the DJ explicitly wants a video track with the default baseFM standby image.
`ffmpeg.inputHint`	string	Human-readable hint explaining when to use each command.

The deprecated stream.accessGrantedBy, obsSettings, streamType, and playback response fields have been removed. Use the Stream status endpoint to read playback URLs and Mux state during a session.

Errors

Code	Description
400	Wallet address required, or USDC payment verification failed (the response `error` includes the verification reason)
402	Payment required. The caller does not hold the BASEFM token threshold and has no community guest pass, and no `txHash` was provided. The response includes `fee` (USDC) and a human-readable `message`.
403	Community guest pass only works with the claimed Agentbot wallet. Returned when the caller has a community pass but the `wallet` in the request does not match their claimed wallet address. The response includes the expected `wallet`.
409	`active_session_exists` — a non-expired current session already exists for this wallet and the authenticated caller does not own it. Owners receive the recovery response above instead.
429	`cooldown_active` — the wallet ended a previous session less than 24 hours ago and is in the cooldown window. Admin callers (authenticated with an email on the platform admin allowlist) bypass this check.
500	Mux is not configured or stream creation failed

When access is granted via a community guest pass (not BASEFM tokens), the stream is created using the caller’s claimed Agentbot wallet address regardless of the wallet value in the request. The stream.wallet and session.wallet fields in the response reflect the claimed wallet.

Before checking for a blocking session, the endpoint automatically ends any expired current sessions for the wallet. This means that if a previous session exceeded the 2-hour maximum but was never explicitly stopped, it is cleaned up and the caller can start a new stream without manual intervention.

Admin cooldown bypass: When the request is made by an authenticated user whose email is on the platform admin allowlist, the 24-hour post-session cooldown is skipped. This lets admins run same-day stream tests. The bypass is tied to the authenticated session — it cannot be triggered from the request body or query parameters. All other access checks (BASEFM token balance, community guest pass, or USDC payment) still apply, and normal DJs remain rate-limited by the cooldown.

Check session status

GET /api/basefm/streams

Returns the active DJ session for the authenticated caller. Authentication is resolved from either a session token or a user session (see authentication below).

Authentication

The endpoint accepts two forms of authentication, checked in this order:

Session token — pass the accessToken returned by POST /api/basefm/streams as a sessionToken query parameter or an x-basefm-session header.
User session — a standard authenticated session (cookie-based). The endpoint looks up the most recent active session for the authenticated user.

Query parameters

Parameter	Type	Required	Description
`sessionToken`	string	No	Session access token from `POST /api/basefm/streams`. Alternative to the `x-basefm-session` header.

Errors

Code	Description
401	Unauthorized — no valid session token or user session
403	Forbidden — the session token does not match the session owner

The wallet query parameter is no longer used. Session lookup is now based on the authenticated caller (session token or user session). Requests using the old ?wallet= parameter are ignored — you must provide authentication instead.

End session

DELETE /api/basefm/streams

Ends the authenticated caller’s current DJ session and retires the corresponding Mux live stream. Replay assets are deleted by default to avoid ongoing storage costs. Uses the same authentication as the check session endpoint (session token or user session).

Query parameters

Parameter	Type	Required	Description
`sessionToken`	string	No	Session access token from `POST /api/basefm/streams`. Alternative to the `x-basefm-session` header.

Headers

Header	Required	Description
`x-basefm-session`	No	Session access token. Alternative to the `sessionToken` query parameter.

Response

{
  "success": true,
  "message": "Session ended"
}

If no active session exists, the endpoint still returns success: true with "message": "No session".

Field	Type	Description
`success`	boolean	Always `true`
`message`	string	Human-readable status message describing the outcome.

Deprecated: The archive request body field and the ended, muxStopped, archived, archiveCreditCost, deletedAssetIds, and retainedAssetIds response fields are no longer returned. The DJ archive flow is currently unavailable through this endpoint — replay assets are always cleaned up when a session ends.

Get distribution state

GET /api/basefm/distribution

Returns the current distribution state for the baseFM station, including the origin stream health, first-party page status, and relay destination statuses. No authentication required. The distribution.origin.status field reflects the live origin state:

active — Mux is healthy and a DJ is currently broadcasting.
idle — Mux is healthy but no DJ is live (for example, after a set ended). This is the normal off-air state and does not indicate a problem.
degraded — Mux credentials are missing or the Mux API returned an error. The response falls back to cached session data.

Errors

Code	Description
500	Internal error and no cached session data is available

When Mux credentials are missing or the Mux API is unreachable, the endpoint returns a degraded distribution state based on cached session data with HTTP status 200 (as long as cached data exists). A 500 is only returned when both the Mux API and the session cache are unavailable.

Relay playback verification

When building the distribution state, the platform verifies that each relay destination is serving the current Agentbot playback ID. For relays with a configured probe URL, the platform fetches the relay’s live API and checks whether any of the returned streams include the current Mux playback ID.

If the relay’s live API returns a stale or mismatched playback ID, the relay is marked status: "degraded" with note: "Relay live API is not serving the current Agentbot playback id."
If the relay’s live API includes the current playback ID, the relay stays status: "healthy" with note: null.

This verification ensures that downstream consumers (such as basefm.space) are actually serving the same stream that Agentbot is broadcasting, and prevents the distribution state from reporting a relay as healthy when its content is stale.

Mux webhooks

POST /api/webhooks/mux

Receives and processes Mux webhook events. This endpoint verifies the request signature using HMAC-SHA256 and rejects unsigned, expired, or tampered requests.

This endpoint is intended to be called by Mux only. You must configure the MUX_SIGNING_SECRET (or MUX_WEBHOOK_SECRET) environment variable for signature verification. When the signing secret is not configured, all requests are rejected.

Headers

Header	Required	Description
`mux-signature`	Yes	Mux webhook signature in the format `t=<timestamp>,v1=<signature>`

Signature verification

The endpoint performs the following checks:

Rejects requests missing the mux-signature header (401)
Rejects requests with a timestamp older than 5 minutes to prevent replay attacks (403)
Computes HMAC-SHA256 over <timestamp>.<body> using the signing secret
Performs a timing-safe comparison of the computed signature against the provided signature (403 on mismatch)

Handled event types

Event	Behavior
`video.asset.ready`	Archives HD assets (1080p or higher) longer than 15 minutes. Shorter or lower-resolution assets are queued for deletion.
`video.live_stream.active`	Marks the corresponding DJ session as `live` in the database and updates the playback ID. Triggers social amplification.
`video.live_stream.connected`	Same behavior as `video.live_stream.active`.
`video.live_stream.idle`	Transitions DJ sessions with status `live` back to `active` in the database. Triggers AI set summary generation.
`video.live_stream.disconnected`	Same behavior as `video.live_stream.idle`.

The webhook handler now syncs DJ session state to the database when live stream events are received. This enables the session cache used by the GET /api/basefm/live endpoint for degraded-mode fallback.

Response

{
  "received": true
}

Errors

Code	Description
401	Missing `mux-signature` header
403	Invalid signature or expired timestamp
500	Webhook processing failed
