Blockchain And Crypto x402 offerings

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Chain-read protocol constants: base rate, epoch length, floors, and where each one was last read from.

Query Ethereum contract event logs via eth_getLogs - filter by contract, topic, and block range

Live wallet balance - native ETH plus up to 20 caller-supplied ERC20 tokens in one bounded RPC batch

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Vault snapshot history. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.

Check if an Ethereum address is a contract via eth_getCode - returns deployed bytecode

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. The current epoch's regime (expansion or contraction), signal, policy multiplier, net ETH flow and STANDARD issuance, plus time to epoch close. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Supply ledger history. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Governance and parameter-change history, queued changes awaiting effect, feature switches, and guardian pause state. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.

Best-effort contract introspection via batched RPC - bytecode presence, token metadata, and ERC20-like/ERC721/ERC1155 classification

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Backing-ratio history, joined against circulating supply as of each snapshot block. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Whether the contraction vault's next buyback tick can fire, its ETH capacity, cooldown remaining, and recent executed ticks. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Latest AMM pool state: price, tick, liquidity, reserves. reserve_eth_raw and reserve_std_raw are 18-decimal token amounts; divide them by 1e18. sqrt_price_x96_raw is Q64.96, and liquidity_raw is Uniswap liquidity rather than a token amount.

Estimate the gas a transaction will consume via eth_estimateGas before signing it

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. A current-pace projection of the Central Bank's policy multiplier and issuance rate if the current epoch's net flow direction holds until close. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. How concentrated Charter and Branch ownership is across wallets, including a standard concentration score and a genesis-versus-auction breakdown.

Deepstate, the on-chain order-book exchange on Robinhood Chain. Trade tape for a market, newest first.

Full Ethereum transaction details by hash via eth_getTransactionByHash - from, to, value, calldata, block

Paylyte grades a locked claim against the official BLS or Board print, then stamps the record on Bitcoin. You buy Proof of Outcome: the hashed official payload, the grade, and the OpenTimestamps record. It is $9.99 per print_id. A Consumer Price Index morning is two buys ($19.98) if both print_ids are sold. Not a raw BLS dump. Not an official BLS or Board product. Agent Trust Score comes from graded claims.

SendCheck deep scan: the same verification across all 5 chains (Base, Ethereum, Arbitrum, Optimism, Polygon) incl. wrong-network detection. POST {address, chain}

SendCheck: pre-send verification of any EVM address on one chain (EIP-55 checksum, wallet-vs-contract, outgoing activity, balances, verdict). POST {address, chain}

Buyable: one URL, one card. Unpaid 402 dry-read. Says if a stock x402 v2 EVM client can pay. Does not settle. Does not send funds. Informational only. Not an endorsement of the resource. Not a guarantee a later settle will succeed.

Batch 1-1000. Returns per-address valid plus detail codes.

Recensus KYA Check: one Know Your Agent check of any agent on Robinhood Chain (4663): what it has done on-chain, who stands behind it and how much it has at stake. Facts and flags, never a score. Replace the last path segment with any address, agent ID or erc8004:<tokenId>. Independent project. Not affiliated with, endorsed by, or officially connected with Robinhood Markets, Inc.
