Data Marketplace

Overview

Data Marketplace is a service for finding, evaluating, buying, and selling machine-ready datasets. Analysts can use its dashboard, while AI agents can use an API, REST endpoints, a hosted MCP server, or an OpenAPI specification to discover, query, and purchase data. Each dataset listing includes a machine-readable schema, data dictionary, and automated PII detection report. Buyers can preview 50 rows and filter by format, license, recency, and quality score. Uploads are scored for completeness, freshness, and consistency; after payment clears, purchased datasets can be downloaded as CSV, Parquet, or JSON. Buyers can post data requests with a reward, and providers can compete to fulfill them; payment is due only if the result meets the stated specification. Datasets are scanned for personal information before publication, but uploaders are responsible for having a lawful basis to share personal data. The terms call the service an early-access beta, with features that may change or be removed and no guarantee that data will be retained. The free plan costs 0.00 USD per free; Starter costs 19.00 USD per month.

Who it is for

Data Marketplace suits analysts looking for structured datasets and sellers publishing them, as well as AI agents accessing data through its API interfaces. Its bounty feature may suit buyers whose needs are not met by existing listings.
