Databazaar

Connects Claude to DataBazaar's agent-native data marketplace via REST API. Exposes tools to search and purchase datasets, create and publish your own listings, and post bounties for data you can't find. Free datasets download directly; paid ones go through Stripe with 24-hour escrow. The search_datasets tool hits their /datasets endpoint, buy_now handles purchases, and log_data_gap creates bounties that sellers compete to fulfill. Useful when your agent needs training data, research corpora, or niche datasets and you want it to handle discovery and transactions programmatically instead of manually browsing marketplaces.
