Can an assistant vote for me or pay for me?

Neither. People on the site cast the votes, and you pay on a checkout page of your own, reached through the checkout link the API returns.

Can I use Best Biz Launch from Claude, ChatGPT, Cursor or VS Code?

Yes, it works with all of them. Add the MCP server URL as a custom connector or MCP server; reading is instant, and the first write sends you to a browser to connect your account.

Does it cost anything?

The API and the MCP server are free: there is no charge within the published rate limits. What you buy, such as a paid launch, is priced on the pricing page.

Is there a risk of the AI making up facts about my product?

The AI draft is built to stay with what your own website says. Anything it cannot verify is left blank and marked, and before anything goes live you review every field and can change any of it.

Can I use an API with Best Biz Launch?

Yes: /api/v1 is the free REST API (OpenAPI) and /mcp is the remote MCP server. No sign-in is needed to read public data; to submit or manage your listings you sign in to your account with OAuth or an API key.

Best Biz Launch developer programme: API and MCP

Connect to Best Biz Launch with your own code or with an AI assistant. Everything below works through both the REST API and the MCP server, under the same rules: search every launch, read leaderboards and founder stories, submit a product by its website address, edit your listing and get a checkout link for paid launches.

MCP server: https://bestbizlaunch.com/mcp (Streamable HTTP)
REST API: https://bestbizlaunch.com/api/v1
OpenAPI 3.1: https://bestbizlaunch.com/api/v1/openapi.json
Sign-in: OAuth 2.1 for apps, or a personal key from API keys
Version: 1.0.0 (changelog)

Bring your AI assistant

Give any MCP client, such as Claude, ChatGPT, Cursor or VS Code, the address https://bestbizlaunch.com/mcp as a custom connector or MCP server. Then ask “What launched this week in my category?”, “Find alternatives to my competitor” or “Launch my product https://example.com”. Nothing more is needed for reading; the first time you change something, a browser opens in your app so you can connect your account. Step-by-step for each app.

Rules of use

The prices you read through the API come from the pricing of Best Biz Launch (list_products). They are in US dollar cents and exclude VAT.
If the product's own website does not say it, the AI does not write it: the field is left blank and marked, and the drafts quote their evidence.
Billboard and sponsorship placements are labelled as paid, and they do not mix with the community rankings, which come from votes only.
You cannot vote through the API or MCP server. A vote on Best Biz Launch only ever comes from a person using the site.
Paying is always a human step on a checkout page. The API supplies the link and takes no card details at any point.
