How to build your own market

Four ways to start

In your Business Builder, press + Build a business (at the top of the left column, or Start a new business on its home page). It offers three ways:

1. Bring your own market. Give it a name and describe it in a few sentences — what is offered, what you choose, how you learn whether you were right, where the history could come from. It becomes a private market of yours, and you go straight on to claim it: a robot starts discovering where its deals and outcomes come from.
2. Set up a market with your agent. Talked a market through with Claude, ChatGPT, Codex or another agent? Copy one prompt into that conversation: your agent writes the market definition, checks it with your app, shows you a summary, and creates the market and its business once you agree. An agent that cannot reach your app can hand you the definition instead — paste it, Check, then Create. The prompt carries your workspace link: give it only to your own agents.
3. Start from a market in this store. Open one and press Run business: your Business Builder opens with it, paused — press Start when you are ready. Your business gets its own copy, which you can improve and publish as your own version. It stays in the original's family: its card and page say “Built on …”, it sells at the original's price, and every sale pays the original's publisher.

The fourth starts here, on the store: type your idea into its box — What world's inefficiency do you want to solve today? — and press Run business: Business Builder opens Bring your own market with it. Without an account yet, the store keeps the idea while you create one.

What a market carries

A definition from your agent is one JSON document of up to 200 KB. A new market needs a name, a one-line short and a long description; menu, data_sources, outcomes, cadence, execution and links are recommended. A definition that contains a secret is refused.

A published market is a set of text files the robot packages for you when you publish — under 5 MB, with no credentials in it:

• market.json — its name, a one-line summary, the menu, data_sources, and optionally how orders are placed (execution) and links;
• business_description.md — the business description P34 is sent;
• a summary for people — the market summary you write on the business's Market tab is the store card's text (a README.md or MARKET_SUMMARY.md counts too);
• the scheme (scheme.json or SCHEME.md) — every party in order, its side (buys, sells, both) and its site;
• the robot kit — skills (skills/*.md) and collectors (collectors/…), and schema.md, the data dictionary;
• optionally a data pack — your menus and sales tables, cleaned before they go.

Depth levels

Every version is checked against these levels when it is published; each level needs all the ones below it. A market's page shows the checklist, so you can see what it still misses. HyperC's own markets keep a level HyperC curates.

Publishing from Business Builder

Open the business's Settings tab and press Publish this market…. You choose:

• where it goes — an update of a market you already published, or a new market;
• who can see it — public (listed in the store), unlisted (anyone with its link) or private (only the people and groups you share it with) — and which of your groups get it, whichever you choose;
• categories — up to 3; with none chosen it keeps those of the market it came from;
• a price — free, or $0.10 to $10,000, paid once (under $0.50 a market is bought with credits only: a card payment can't be that small); buyers get every later version, and every market built on it (one purchase covers the whole family). A market built on another market has no price of its own: it sells at the original's price, and its sales pay the original's publisher. HyperC keeps 30 % of each sale, and sales open once HyperC opens them;
• the card's text (your market summary — it can't be a draft) and an optional image (PNG, JPEG or WebP, at most 2 MB and 4096 px a side);
• an optional data pack (your own trades and P34's past choices are removed first), the default robot model for those who deploy it, and notes on this version.

A free market with nothing flagged in it is published at once. HyperC reviews it first when it has a price, when the scan flags something, or when it is built on another member's private market or a members-only kit. My markets in Business Builder is where you change the card, unlist or delete it, and see its versions, sales, ratings and the results buyers share back; you change its price there or on its page here (the original's publisher sets the price of a whole family).

What you earn. A free market earns royalty points when other members run it, by its level (L1 2 %, L2 5 %, L3 8 %, L4 12 %, L5 15 %); a priced market earns from its sales — bought with credits or by card, every sale of it and of every market built on it books 70 % to you as earned credits: a record, not paid out and not added to your wallet (HyperC decides later how they can be used). Buyers can share their realized trades with you, anonymized. Business Builder apps that share their results also report what each market earned with real money; once 3 or more members report on a market's family, its cards show how many run it, what they earned together and how many trades.

Sharing it

On your market's page here (Manage sharing ↗ in Business Builder opens it) you can change who can see it, copy an unlisted market's link or make a new one (the old one stops working), share it with people by e-mail and with your groups, and make an invite link — one link for many people, which expires after 1, 7 or 30 days or never, can be limited to a number of people, and can be turned off. A group's page has Share a market here for the markets you publish. Markets you buy, get free or are given are in Markets I own (the store's rail, and My library). A market's page is public: anyone with its link can read it. Browsing the whole store, collections, a market's forks and every button on a market need a free HyperC account.

Sharing never makes a priced market free. Sharing with people by e-mail, with a group or by an invite link lets them see a market, and a priced one is still bought before it is used: only a purchase or a gift lets them use a priced one. Bought a market? Gift it to up to 2 friends by e-mail from its page: each gift is bound to their e-mail address and is theirs, free, once they sign in with it; a gifted market can't be gifted on, and a refunded purchase takes its gifts back.

In a group, members may invite people too — a group can limit it to a number each (a new group starts at 3 each), and its owner and admins can always invite and reset a member's count. Collect markets with ☆ Favorite and + Collection — a market someone sent you by its link stays in the store for you once you keep it; your collections and groups are in My library. The store lists your favorites first, then what is shared with you, then the rest by what members run and rate lately (Recommended) — or sort it by newest, price, popularity, level or best rated.

Going up a level

• L1 Described — write at least 200 characters of market summary and of business description.
• L2 Sourced — say where the data comes from (data_sources) and who sells: the scheme, or how orders are placed and the links. Ask the robot to keep them in what it publishes.
• L3 Skilled — keep at least one skill or collector in the kit.
• L4 Data-backed — include a data pack with menus and sales rows.
• L5 Proven — comes from buyers sharing their realized results (3 or more buyers, 10 or more trades).
• Improved it? Publish a new version — every version is checked again.
