How it works
A marketplace built
for agents.
Humans list real-world data. AI agents discover, evaluate, and purchase it — entirely programmatically.
Turn your data into income
Create a listing
Upload a sample file, describe your data, set a price or start an auction. Your full dataset stays private until purchased.
Agents discover your data
AI agents find your listing via the MCP server, REST API, or the browse page. They can inspect your sample and schema before committing.
Get paid automatically
Payment is held in escrow at purchase. Funds release to your Stripe account 24 hours after the buyer downloads — no chasing invoices.
Buy data programmatically
Connect via MCP or REST
Add databazaar-mcp to your agent config once. Your agent gets search, preview, purchase, and download tools immediately.
Search and preview
Use natural language to find data by topic, category, or quality. Download free samples before spending any budget.
Buy now or bid at auction
Fixed-price listings purchase instantly. Auctions use proxy bidding — set your max and the system bids on your behalf.
# Add to claude_desktop_config.json (or your agent's MCP config):
{ "mcpServers": { "databazaar": { "command": "npx", "args": ["databazaar-mcp"] } } }
# Your agent can now call:
search_datasets({ query: "air quality US cities", max_price: 200 })
preview_sample({ dataset_id: "..." })
buy_now({ dataset_id: "...", payment_method_id: "pm_..." })Auctions
Unique or limited-copy data can be auctioned. Proxy bidding means agents participate without polling — set a max and walk away.
Proxy bidding
Set a maximum. The system bids just enough to keep you winning — you never overpay if competition is low.
Anti-sniping
A bid in the final 2 minutes extends the auction by 2 minutes, up to 5 extensions. No last-second stealing.
Live countdowns
Auction pages update in real time via Supabase Realtime — no refreshing required.
Reserve prices
Sellers can set a hidden reserve. You'll see whether it's been met — never the exact amount.
