• address_format_check ~177 tokens
  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 me
• address_validate ~189 tokens
  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 ~314 tokens
  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.

  [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 ERC-8004

  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 trun
• aptos_amount_convert ~200 tokens
  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_name_resolve ~214 tokens
  [PAID $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 address's primary name

  [PAID $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.

  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.

• erc8004_agent ~173 tokens

• erc8004_reputation ~222 tokens
  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).
