Tools it offers

17 tools, as the server itself reported during our check on Oct 31, 2026.

• buy_timeBuys line time by the millisecond, $0.000001 each; buying again adds time. Returns your channelId, the time bought and the time left. Then open a line with the line tool. Time you do not burn comes back on refund. Not id
• lineOpens a line: calls on it spend bought time and carry no payment. op: open {channelId} takes the channelId buy_time returned and answers {nonce, sign}; sign the text in sign with the payer key (EIP-191, personal_sign); p
• get_payment_termsReturns what ZEAM :: Prism costs and the three ways to pay: a pass, ZEAM :: Pass with your own wallet, or your own x402 client, or an MPP client where the 402 carries a Payment challenge. With them: the x402 quote, the p
• get_operatorReturns who runs ZEAM :: Prism, our operating theory, how we work, and how to check each claim. Free, no arguments. Example: {}
• attest_serverReturns the whole report on one MCP endpoint in one answer, read section by section: handshake and contract, then the payment surface, then discovery. A section that could not be read is named in failed with the reason a
• attest_contractReturns the handshake and contract of one MCP endpoint: initialize (protocol, server, capabilities, latency), what a plain GET returns, and tools/list rendered to a canonical snapshot with a stable hash, its context foot
• attest_paymentReturns how one MCP endpoint refuses an unpaid call. Calls a tool with no payment, first with the caller's arguments or {}, then, when that is refused for its arguments, with the example the server publishes or arguments
• attest_discoveryReturns the plain-document surface of one MCP host: which standard discovery paths answer (well-known mcp, agent card, x402, ai-catalog, owners, llms.txt, openapi, server.json, robots, sitemap), and an openapi audit: ope
• attest_driftReturns every change between two contract snapshots, classed as breaking, compatible or cosmetic, with the rule that decided each. Pass a prior attest_contract answer as `before` and either a later one as `after` or a `u
• audit_payersWho is really buying from an x402 seller on Base: each payer that opened a payment channel with the seller's escrow, and how many channels each opened. It counts the payers, not the relayers that submit their transaction
• audit_fundersWhere a wallet's USDC on Base came from: every address that sent it USDC, with amounts, transfer counts and block ranges. A sender that is a contract (an escrow refund, a router, a bridge) is marked as a return path, not
• audit_clusterWhether a set of wallets on Base is one actor: who funded each with USDC, grouped by shared funder, with a verdict and the wallets it could not resolve. Turns "55 distinct payers" into "one actor with 55 wallets", or fai
• notes_signReturns the data to sign so a note posts under your wallet's name. Free. Sign the typed_data it returns with eth_signTypedData_v4, then pass the same body, your address, your signature and the returned salt to notes_post
• notes_postWrites a note on an immutable notepad and returns its Base transaction. Free; we pay the gas. Each note is an event on a Base contract that nobody can edit or delete, us included. To post under your wallet's name, sign i
• notes_readReturns the notes on the notepad, newest first. Nothing is filtered or removed: a note anyone sends again word for word is listed again, with replay_of naming the first. Each note carries its Base transaction, and a sign
• call_rpcCalls a JSON-RPC method on an Ethereum or Base node we run and returns the node's own answer, unchanged. Base serves eth_, net_, web3_, txpool_, debug_ and base_ methods; Ethereum serves eth_, net_, web3_, txpool_, debug
• sample_rpcCalls one read-only method on the nodes call_rpc uses and returns the node's own answer with how to check it against another source. Free, to check the nodes before you pay. No wallet. Eight read-only methods: eth_chainI
