What it can do
| Tool | What it says it does |
|---|---|
address_format_check | Checks whether a string is a well-formed address for EVM (EIP-55 checksum), Solana, Aptos (AIP-40) or Bitcoin (base58check, bech32, bech32m). With family "auto" it lists every family the string could be, and never picks one. A valid format is not evidence an address is safe, owned, or the one you… |
address_validate | Validates an address for a chain and returns its canonical form. EVM: EIP-55 (a wrong checksum is refused, never corrected). Aptos: AIP-40 strict form. Says only what can be known offline; it never guesses what kind of account an address is. |
agent_register_prepare | Step 1 (free): builds the ERC-8004 registration file and A2A agent card LogicNodes will host for your agent, and the exact message your agent address must sign (personal_sign) to publish them with agent_register_publish. |
agent_register_publish | [PAID $5.00 USDC per call via x402] Step 2: with the signature from agent_register_prepare, LogicNodes hosts the registration file at https://logicnodes.io/a/<address>/registration.json and the agent card next to it, and returns the unsigned transaction that calls register(tokenURI) on the… |
aptos_address_validate | Validates an address against the Aptos address standard (AIP-40) and returns its canonical form: special addresses (0x0-0xf) as short form, all others as 0x + 64 digits. Strict by default; mode=relaxed also accepts a missing 0x or a few dropped leading zeros, and says which spelling you used (a… |
aptos_amount_convert | Converts between a human decimal amount and integer base units, using the asset's decimals read LIVE from the chain (never assumed from a symbol). Refuses to round: more decimal places than the asset has is an error. An ambiguous symbol returns AMBIGUOUS_INPUT. |
aptos_asset_resolve | [FREE: 25 calls/day, then $0.001 USDC per call via x402] Turns a symbol, registry id, fungible-asset address or coin type into one asset, with its on-chain symbol/name/decimals read live. Several different assets share the symbols USDC and USDT (Circle/Tether native vs LayerZero-bridged); those… |
aptos_balance_get | [FREE: 25 calls/day, then $0.002 USDC per call via x402] Balances of an address for APT and fungible assets, all read at ONE ledger version (stated, or the current one pinned). Amounts are exact integer strings plus decimal strings. Default assets: APT and every verified asset; pass `assets`… |
aptos_fee_estimate | [FREE: 25 calls/day, then $0.005 USDC per call via x402] Gas unit price tiers (deprioritized/regular/prioritized) plus the cost of common transactions in octas, APT and USD. Gas units are MEASURED by simulating real transfers now, not taken from a table. USD comes only from two independent… |
aptos_name_resolve | [FREE: 25 calls/day, then $0.001 USDC per call via x402] name -> address, or address -> primary name (give exactly one). A name resolves to its TARGET address, which can differ from its owner; a registered name with no target resolves to nothing (NOT_FOUND) and its owner is never substituted. An… |
aptos_tx_decode | [FREE: 25 calls/day, then $0.002 USDC per call via x402] Explains what an entry-function payload would do, in plain English, with every argument type-checked against the module ABI and amounts shown using the asset's live decimals. Known patterns (transfers, batch transfers, key rotation, code… |
aptos_tx_simulate | [FREE: 25 calls/day, then $0.005 USDC per call via x402] Runs an UNSIGNED entry-function transaction through the node's own simulator (no key needed, nothing is submitted) and returns success or the abort decoded in plain English, exact gas and fee, balance changes, and events. Arguments are… |
aptos_tx_status | [FREE: 25 calls/day, then $0.001 USDC per call via x402] Committed, failed, pending or not found for a transaction hash, with the VM status explained in plain English (Move aborts decoded to module, error name, code and category; the raw status is always included). Fee is computed from the VM's… |
aptos_view | [FREE: 25 calls/day, then $0.002 USDC per call via x402] Calls a Move #[view] function read-only, after checking every type argument and argument against the module's ABI: u64/u128/u256 must be decimal strings, vector<u8> a 0x hex string, Option<T> written {"vec":[]} or {"vec":[value]}, addresses… |
audit_log_append | [FREE: 25 calls/day, then $0.001 USDC per call via x402] Adds one entry (any JSON object up to 8 KB: a payment, a decision, a delivery, ...) to your log. Returns its sequence number, its chain hash and the receipt digest that will be in today's Bitcoin-timestamped root. Needs the log's write key. |
audit_log_create | Creates a logbook for an agent or business. Returns the log id, a write key (to append) and a read key (to export), shown only once. Every entry is hash-chained and timestamped into Bitcoin through the daily receipt root. Free to create; appending costs per entry. |
audit_log_export | Returns entries of your log (up to 1000 per call, from fromSeq), re-verifies the whole hash chain, and gives each entry's Bitcoin proof status (pending until its day's root is built and timestamped). Needs the log's read key. |
business_days | [FREE: 25 calls/day, then $0.001 USDC per call via x402] Counts business days between two dates, adds business days to a date, or tests whether a date is a business day.

counterparty_check | [FREE: 25 calls/day, then $0.003 USDC per call via x402] Before paying or delivering to an agent or address: checks sanctions lists, on-chain activity on Base and Ethereum (wallet, contract or EIP-7702 wallet; transaction counts), whether it owns an ERC-8004 agent identity, its record of deals… |

deal_dispute_review | [PAID $1.00 USDC per call via x402] For a deal recorded by the LogicNodes deal notary: verifies the signed, hash-chained record and gives an ADVISORY ruling from fixed rules (R0, R1, R2, R3, R4, R5, R6: settled, delivered and checked, failed check, uncheckable, never delivered, never agreed)… |
decimal_calc | Add, subtract, multiply, divide, raise to an integer power, compare, or take a percentage, on decimal STRINGS with exact arithmetic (no floating point).

Give exactly one of name or address. A reverse result is returned only if that name resolves back to the… |
erc8004_agent | Reads an agent from the ERC-8004 identity registry on Base: its owner address and the registration URI it points to, at one stated block. The URI is reported, not fetched (fetching arbitrary URLs for you is not this tool's job). An id that was never minted is NOT_FOUND. |
erc8004_reputation | Summarises the feedback posted about an agent in the ERC-8004 reputation registry on Base, at one block: number of distinct clients, number of feedback entries, the registry's own summary value, and each client's latest entry (value, tags, revoked).

Each… |
evm_log_decode | [FREE: 25 calls/day, then $0.001 USDC per call via x402] Decodes one event log (its topics and data) against an ABI that YOU supply and returns the event name and arguments. If no event in your ABI matches topic0 it says so rather than guessing from a database of known events. |
evm_logs | [FREE: 25 calls/day, then $0.003 USDC per call via x402] Logs emitted by one contract in a block range of at most 2000 blocks, optionally filtered by topics. Refuses (rather than truncates) when more than 1000 logs match, so an answer is always complete. |

loan_calc | [FREE: 25 calls/day, then $0.001 USDC per call via x402] Monthly payment, total interest and total paid for a fixed-rate amortizing loan, in exact arithmetic.
