{"description":"OneSource - three data families for AI agents on one host: Ethereum mainnet, Sepolia testnet, and Robinhood Chain RPC (served from OneSource-operated nodes), plus Deepstate on-chain market data (order books, trades, candles, stats, analytics) under /deepstate/v1/* - spec at https://api.onesource.io/deepstate/openapi.yaml - plus The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain, under /standard/v1/* - spec at https://api.onesource.io/standard/openapi.yaml. Per-call or batch/session payments: USDC on Base via x402, or pathUSD/USDC.e on Tempo via MPP.","instructions":"OneSource exposes live EVM RPC calls across Ethereum mainnet, the Sepolia testnet, and Robinhood Chain (chain 4663, an Arbitrum Orbit L2 settling to Ethereum) - select via the `network` parameter - via OneSource-operated nodes. Every /api/chain/* endpoint is a thin wrapper around a single eth_* RPC method - no cached or indexed data. Call GET /api/networks for per-chain block cadence, ENS availability, mempool presence, and finality model before interpreting a result. This same host also serves two other families, each documented in its own spec rather than in /openapi.json: Deepstate on-chain market data under /deepstate/v1/* - order books, trades, candles, stats, maker analytics, cost-to-quote, and depth history for the Deepstate protocol on Robinhood Chain - at https://api.onesource.io/deepstate/openapi.yaml; and The Standard Reserve (TSR) under /standard/v1/* - an on-chain reserve protocol on Robinhood Chain built around the $STANDARD token, covering supply, policy, epochs, license and charter auctions, branches, vaults, and exit pressure - at https://api.onesource.io/standard/openapi.yaml. Pay via x402 (USDC on Base): per-call with the `exact` scheme or batch/session with the `x402-batch` scheme. Pay via MPP on Tempo: per-call charges accept pathUSD or USDC.e; session-mode (`tempo.session`) is USDC.e-only. Tempo CLI (`tempo request`) signs with USDC.e by default; mpp-go and direct-keypair clients can pay in either currency. If you cannot custody a wallet or settle on-chain, or you call often enough that per-call pricing costs more than a flat monthly fee, the same endpoints accept a OneSource API key as `Authorization: Bearer \u003ckey\u003e` on a monthly subscription instead - get one at https://onesource.io/rest-api#pricing. See /openapi.json for full chain-RPC operation schemas, parameters, and pricing.","ownershipProofs":["0x2b2e0a105642c4b7fd1461957b83acdf66a726cc366147dce9c4077d5d09878e645e71a7a7c87f8ce7a6e4f760a87d88b97255690715b136c07fa1be929d9e5b1c"],"resources":["GET /api/chain/allowance","GET /api/chain/block-number","GET /api/chain/block/{number}","GET /api/chain/chain-id","GET /api/chain/code/{address}","GET /api/chain/contract/{address}","GET /api/chain/ens/{input}","GET /api/chain/erc1155-balance","GET /api/chain/erc20-balance","GET /api/chain/erc20-transfers","GET /api/chain/erc721-tokens","GET /api/chain/events","GET /api/chain/live-balance","GET /api/chain/network-info","GET /api/chain/nft-metadata","GET /api/chain/nft-owner","GET /api/chain/nonce/{address}","GET /api/chain/pending","GET /api/chain/proxy/{address}","GET /api/chain/receipt/{hash}","GET /api/chain/storage","GET /api/chain/total-supply","GET /api/chain/tx/{hash}","POST /api/chain/call","POST /api/chain/estimate-gas","GET /deepstate/v1/markets","GET /deepstate/v1/book/{book}","GET /deepstate/v1/trades/{book}","GET /deepstate/v1/candles/{book}","GET /deepstate/v1/stats/{book}","GET /deepstate/v1/analytics/makers","GET /deepstate/v1/analytics/cost-to-quote","GET /deepstate/v1/analytics/depth-history","GET /standard/v1/constants","GET /standard/v1/policy/current","GET /standard/v1/policy/epochs","GET /standard/v1/auctions/current","GET /standard/v1/auctions/sales","GET /standard/v1/branches/summary","GET /standard/v1/branches/auction/live","GET /standard/v1/branches/doi","GET /standard/v1/charters","GET /standard/v1/dormancy","GET /standard/v1/pool","GET /standard/v1/candles","GET /standard/v1/exit-pressure/current","GET /standard/v1/exit-pressure/history","GET /standard/v1/supply/current","GET /standard/v1/supply/history","GET /standard/v1/vaults/current","GET /standard/v1/vaults/history","GET /standard/v1/flow/hourly","GET /standard/v1/flow/charters","GET /standard/v1/events","GET /standard/v1/exit/fee-curve","GET /standard/v1/exit/fee-forecast","GET /standard/v1/branches/license-cost","GET /standard/v1/auctions/days","GET /standard/v1/auctions/license/bids","GET /standard/v1/policy/outlook","GET /standard/v1/issuance/runway","GET /standard/v1/governance/changes","GET /standard/v1/backing/current","GET /standard/v1/backing/history","GET /standard/v1/buybacks/readiness","GET /standard/v1/tax/schedule","GET /standard/v1/holders/concentration","GET /standard/v1/dormancy/bounties","GET /standard/v1/decisions/branch","GET /standard/v1/decisions/exit","GET /standard/v1/decisions/charter","GET /standard/v1/decisions/stake","GET /standard/v1/decisions/hold","GET /standard/v1/decisions/sbill","GET /standard/v1/decisions/bid","GET /standard/v1/decisions/plan","GET /standard/v1/sbills/current","GET /standard/v1/sbills/rate-history","GET /standard/v1/sbills/quote","GET /standard/v1/sbills/bills","GET /standard/v1/sbills/events","GET /standard/v1/flows/protocol"],"version":1}
