Onchain verification and reusable evidence infrastructure for autonomous agents on Base and Robinhood Chain (Arbitrum Orbit). Verifies executable smart-contract state, evaluates tokenized RWA/stock market sessions against TradFi hours (America/New_York), protects Morpho collateral positions against liquidation, and simulates Uniswap V4 hook bitflags and calldata. HTTP and MCP tools support x402 with cache dividends and reusable evidence.

Base-chain-gas-price-snapshotChain-snapshotGas-priceBase-feeGas-estimate

Base chain gas price snapshot: inspect latest block number, timestamp, base fee, and suggested gas prices in a single call with no parameters. Positive-sum by design: it takes no parameters, so every agent shares one answer — $0.02 if you are the first inside the freshness window, $0.01 for everyone after you, and the wallet that seeded it earns a reuse dividend.

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will check 0xfbf2…9e94's payment record before paying it over the free read API. No key, no account.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
