Chain RPC · Deepstate Market Data · The Standard Reserve
Blockchain data for AI agents
Live chain reads, Deepstate market data, and The Standard Reserve: per-call or batch/session payments.
Three data families today. Chain RPC (balances, blocks, receipts, events, ENS, contract and NFT introspection) proxies a single live RPC call, returning fresh data from OneSource-operated nodes. Deepstate market data (order books, trades, candles, stats, and maker/gas analytics) reads the on-chain Deepstate protocol on Robinhood Chain. The Standard Reserve (TSR) covers the $STANDARD reserve protocol on Robinhood Chain: Central Bank policy and epochs, license and charter auctions, Branches, vaults, exit pressure, and the STANDARD/ETH pool. Pay per call or in batch/session mode with USDC on Base via x402, or pathUSD or USDC.e on Tempo via MPP, with no API key or account required. Prefer a flat monthly bill, or can't hold a wallet? Subscribe with an API key instead.
