API for AI agents
Open datasets API for AI agents
The best way for an AI agent to query open datasets is to call a datasets API per request on Proxygate. Academic catalogs, scientific references, and public datasets are callable from one prepaid USDC balance, settled in USDC on Solana. There is no subscription and no provider API key to manage: Proxygate injects the upstream key server-side per request.

How AI agents use open and reference datasets APIs
A research or data agent searches academic works, scientific records, and public datasets on demand and pays per call instead of bulk-licensing each source. One prepaid balance covers every dataset in the collection, so an agent can stitch sources together in a single run and keep a signed receipt for each request.

Open datasets API for AI agents: frequently asked questions
On Proxygate there are 10 listings that serve open and reference datasets, each callable per request by an AI agent. The agent funds one prepaid USDC balance, calls the endpoint through a transparent proxy, and pays only for the calls it makes, settled in USDC on Solana. There is no single "best" provider: an agent can call any of them from the same balance and pick by price, endpoints, and rating.
Your agent authenticates once to Proxygate and never handles the upstream provider key. Proxygate injects the key server-side per request, so the agent just calls the endpoint and the credential is never shared with or exposed to it.
Yes. Every listing here is billed per request, settled in USDC on Solana from one prepaid balance. There is no monthly minimum and no subscription: an agent pays only for the calls it makes, and each call returns a signed receipt.
Pricing is per request and set by each seller, starting from about $0.001 per call, with per-endpoint pricing that can differ from the base rate. An agent settles each call in USDC on Solana with no monthly commitment. See the Datasets category for the full range of listings.
