Vid0 developers: API and MCP

The Vid0 API is a JSON REST API at https://api.vid0.in. It's the same API the Vid0 Chrome extension and MCP server use. Authenticate with a personal API token.

The endpoints below are described in an OpenAPI 3.1 spec at /openapi.json, with typed parameters and response schemas, ready for API tools and LLM function calling. The API isn't versioned for third parties yet: endpoints live under /v1 and can change. For anything you'd like stable, email [email protected].

Authentication

  1. Sign in and open Settings → API tokens.
  2. Name a token and click Create token. It starts with yti_ and is shown once. Revoke it on the same card.
  3. Send it on every request: Authorization: Bearer yti_…

A token acts as you in your current workspace. Creator tools need a token from a creator workspace, and brand tools one from a brand workspace; the API answers 403 when a token is used on the other side's routes.

curl -H "Authorization: Bearer $VID0_TOKEN" https://api.vid0.in/v1/me

Endpoints

GET /health

Service status (no token needed)

GET /v1/me

Your user, workspace and plan

GET /v1/quota

Today's YouTube API quota buckets

GET /v1/videos/{id}/insights

One video vs. its channel baseline: outlier ×, expected views, views per hour, engagement

GET /v1/channels/{ref}

Channel stats, top outliers and latest uploads. ref is an @handle, a UC… channel id or a channel URL (URL-encoded)

GET /v1/channels/{ref}/best-time

Best weekdays and hours to post, from public uploads

GET /v1/outliers

Videos beating their channel's baseline. Query: channels (comma-separated ids; defaults to your tracked competitors), format (long, short or all), minScore (default 2), maxAgeDays (1–365, default 90), limit (1–200, default 60)

GET /v1/keywords?q={keyword}

Competition, demand and opportunity scores for a keyword, plus the videos ranking for it. Optional mySubs (your subscriber count) adds "winnable for you". Uses one keyword lookup from your plan

Derived numbers (outlier ×, expected views, scores, prices) are labelled “Vid0 estimate, not YouTube data”.

Errors

Errors are JSON with a code, a message and a request id you can quote back to us:

{ "error": { "code": "unauthorized", "message": "Sign in to continue.", "requestId": "…" } }
  • 400 bad_request: invalid parameters or body
  • 401 unauthorized: missing, invalid or revoked token
  • 402 limit_reached: the workspace's plan limit for this feature is used up
  • 403 forbidden: the token's workspace kind (creator or brand) can't use this route
  • 404 not_found: unknown route, video or channel
  • 429 quota_exhausted: today's YouTube API quota is used up, or you're sending too many requests

MCP server

Vid0 has an MCP server with 34 tools: outliers, video and channel analysis, keyword research, your channel's analytics, title and thumbnail scoring, scripts, the content calendar, the ideas board and sponsorships. It speaks stdio and Streamable HTTP (POST /mcp, Authorization: Bearer yti_…). A hosted endpoint isn't public yet; email [email protected] for early access.

For agents

Every public page has a Markdown version: send Accept: text/markdown or add .md to the path. The site map for agents, with when to use Vid0, is at /llms.txt. The API is listed in the RFC 9727 API catalog at /.well-known/api-catalog, which points to the OpenAPI spec, these docs and the health check.
