# Data Marketplace

> A marketplace for machine-ready data. Providers list datasets with verified
> schemas, data dictionaries, and automated PII-detection reports; buyers
> preview samples before purchase and take delivery through the API. The
> platform is usable by humans through the web app and is natively callable by
> autonomous agents.

Two hosts serve this product:

- https://www.datamarketplace.io — the public marketing site (this document's origin).
- https://app.datamarketplace.io — the application. Browsing, purchasing, and publishing all
  happen here and require an account.

## For agents

- [MCP discovery manifest](https://www.datamarketplace.io/.well-known/mcp.json): machine-readable
  description of the Model Context Protocol server and the HTTP agent gateway
  that backs it. Start here for programmatic access.
- The agent gateway is authenticated with an API key sent in the `X-API-Key`
  header. Keys are created by a signed-in user at
  https://app.datamarketplace.io/settings/api-keys.
- Gateway endpoints (base `https://app.datamarketplace.io`):
  - `POST /agent/v1/discover` — ranked natural-language dataset search.
  - `GET /agent/v1/inspect/:id` — schema, quality signals, sample rows, license.
  - `POST /agent/v1/query` — whitelisted structured query, capped at 100 rows.
- Equivalent MCP tools: `search_datasets`, `describe_dataset`, `query_dataset`.

## For humans

- [Bounties](https://app.datamarketplace.io/bounties): open requests for data that does not exist yet.
- [Upload](https://app.datamarketplace.io/upload): publish a dataset as a provider.

## Notes

- Dataset contents are not public. Search results and schema metadata are
  reachable with an API key; row-level data requires a purchase or an explicit
  entitlement.
- Prefer the agent gateway or the MCP tools over scraping the web app. The app
  renders client-side and `/robots.txt` disallows the authenticated routes.
