Free live streaming and video API: what the Free plan includes

The DCAST Partner API has no separate API plan. Anyone who signs up, the Free plan included, can create a key and call the operations; the plan of the account decides how much you can run, and the same limits apply in the dashboard and in the API. This page lists what the Free plan includes, read from the server, and the calls that show the limits of your own account.

The short version: the table below is the live answer of the DCAST plan data for dcast.pro, not a typed copy. The numbers of your own account come from GET /me (plan, planLimits) and GET /quota (storage). A call that reaches a limit answers with a code that names it.

What the Free plan includes

Every value in this table is read from the plan data of the DCAST server when the page is rendered. None is typed by hand; a dash means the server could not be reached for this render.

Limit	Free plan
Video storage	10 GB
Uploaded video quality	720p, up to 120 fps
Live quality	720p, up to 60 fps
Streams at once	1
Viewers per stream	50
Length of one live session	1 h
Live time per month (streams, restreams and rooms together)	10 h
Restream destinations at once	2
Participants in a room	10
Rooms at once	1
Length of one room	30 min

Star, Pro and VIP raise these numbers. Every plan side by side is on pricing, and the numbers the API enforces are also listed in Errors & limits.

Read the limits of your own account

GET /me answers with plan and planLimits, the same object the dashboard reads, so an integration finds its ceilings and feature flags without waiting for a refusal. GET /quota answers with the storage used against the limit. GET /health needs no key.

Call	Auth	What you get
`GET /health`	public	The state of the API: `data.status` reads `healthy` when it is up.
`GET /me`	key	`plan`, `planLimits` and `embedAllowlist`, with the full profile.
`GET /quota`	key	Storage `used`, `limit` and `available` in bytes, plus `usedPercent` and `isExceeded`.
`GET /changelog`	public	The dated list of changes to the API, so an integration notices a change.

curl -s "https://api.dcast.pro/api/v1/health"
# → data.status

curl -s -H "Authorization: Bearer pk_YOUR_KEY_HERE" "https://api.dcast.pro/api/v1/me"
# → data.plan, data.planLimits

curl -s -H "Authorization: Bearer pk_YOUR_KEY_HERE" "https://api.dcast.pro/api/v1/quota"
# → data.used, data.limit, data.available (bytes), data.usedPercent, data.isExceeded

When a limit is reached

The call is refused with an error code that names the limit: for example PLAN_STREAM_LIMIT_REACHED (409) for streams at once, PLAN_RESTREAM_LEG_LIMIT_REACHED (409) for restream destinations and QUOTA_EXCEEDED (403) for storage. The codes are listed in Errors & limits. Do not retry the same call: move the account to a larger plan or free some room.

Your first calls on the Free plan

Sign up on dcast.pro, open Settings → API Keys in the dashboard and create a key.
Read your plan and limits with GET /me and GET /quota.
Create a stream with POST /streams and put it on a page as shown in Embed a live stream.
Upload a video with POST /videos/upload and show your library as shown in Video website.

For AI agents

Connect the DCAST MCP server at https://api.dcast.pro/mcp. Each tool is one API operation, and dcast_get_recipe returns the exact tool-call sequence for a job.

Before promising anything to the person, call get_account for the plan and limits and get_storage_quota for the storage. A plan limit names itself in the error: tell the person which limit it is, ask dcast_search_docs which plan raises it, and do not retry the call.

Never ask the person to create, copy or paste an API key. If the website's own server must call DCAST, call ask_site_access: the person clicks one Allow link and the key goes straight into the site's environment. You never see it.
