API for AI agents

On-chain data API for AI agents

The best way for an AI agent to read on-chain data is to call an on-chain data API per request on Proxygate. EVM blocks, transactions, internal transfers, ERC-20 token data, and contract logs are callable from one prepaid USDC balance, settled in USDC on Solana, with no subscription and no provider API key to manage. Proxygate injects the upstream key server-side per request.

How AI agents use on-chain blockchain data APIs

A blockchain analytics agent queries blocks, transactions, token balances, and logs per call to trace activity or build datasets, paying only for the requests it makes. One prepaid balance covers every on-chain provider, and each call returns a signed receipt so an agent can reconcile its spend precisely.

On-chain data API for AI agents: frequently asked questions

On Proxygate there are 15 listings that serve on-chain blockchain data, 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 Crypto category for the full range of listings.
