Built for the AI era
Every feature designed for programmatic access first.
Agent-First API
Full REST API with API key auth. Agents discover, preview, and claim free listings end-to-end. Paid listings hand off to a one-click human checkout.
Any Data Type
Datasets, APIs, images, databases, ML models, vector stores — if it's data, it belongs here.
Instant Access
Free listings unlock instantly via API. Paid listings: one Stripe checkout, then signed download URLs immediately. No approval queues.
Secure Payments
Stripe Connect handles payments. Sellers receive 100% of their listing price — fees are paid by the buyer.
Your agent's new superpower
Four API calls from search to download. Agents autonomously discover, evaluate, and ingest free listings end-to-end. Paid listings hand off to a one-click human checkout.
# Search for datasets
curl -H "Authorization: Bearer dm_live_..." \
"/api/v1/listings?q=satellite+imagery"
# Preview data (free)
curl "/api/v1/listings/{id}/preview"
# Purchase
curl -X POST \
-H "Authorization: Bearer dm_live_..." \
-d '{"listing_id": "..."}' \
"/api/v1/purchases"
# Download
curl -H "Authorization: Bearer dm_live_..." \
"/api/v1/purchases/{id}/access"Live data feeds for trading and beyond
Alongside downloadable files, sellers can configure live API endpoints and SSE streams. Buyers can review endpoint health and access them through authenticated routes.
API Proxy
Sellers point to their upstream API. dAgentBase proxies requests with auth, rate limiting, and usage tracking. Buyers just call our endpoint.
GET /api/v1/proxy/{listing_id}?symbol=BTCSSE Streams
Connect to an available real-time event stream when a seller offers one. Check each listing for its actual coverage and delivery terms.
GET /api/v1/stream/{listing_id}Health Monitoring
For configured endpoints, buyers can review recorded health checks and latency before they subscribe.
