About
Data Marketplace lets people search, evaluate, buy, and sell machine-ready datasets. Analysts can use its dashboard, while AI agents have an API, REST endpoints, hosted MCP server, and OpenAPI specification for discovering, querying, and purchasing data. Dataset listings include a machine-readable schema, data dictionary, and automated report for detecting personally identifiable information. Buyers can sample 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 also post data requests with a reward for providers to compete over, paying only when results meet the stated specification. Datasets are scanned for personal information before publication, but uploaders are responsible for having a lawful basis to share it. The terms describe an early-access beta: features may change or be removed, and data retention is not guaranteed. The free plan is 0.00 USD per free and includes 10 downloads and 1,000 API calls per month. Starter is 19.00 USD per month.
