Retrieves detailed block data for a specified EVM-compatible chain at a given block height or tag (latest, safe, finalized)

Fetches on-chain metadata for an EVM token (name, symbol, decimals, etc.) at a specified block on any supported EVM chain.

Returns the current transaction nonce for an EVM address at a specified block on any supported EVM chain

Calls a read-only (view) function on the Aptos blockchain and returns the exact result as of a specified ledger version

Fetches the full transaction receipt for an EVM transaction hash on a specified chain

Generates a token spend/receive report for a wallet address on an EVM chain over a specified block range

Computes simple or compound interest for a given principal, rate, and time period with configurable compounding frequency, precision, and rounding rules

Generates one or more verifiable random numbers derived from a specified EVM blockchain block hash, using an optional salt for uniqueness.

Fetch on-chain event logs for a given EVM contract address and topic filters across a specified block range

Resolves Aptos Name Service (ANS) names to addresses or addresses to names on Aptos mainnet or testnet

Counts business days between two dates, adds business days to a date, or checks if a date is a business day — with configurable weekend and holiday rules.

Queries the ERC-20 token allowance granted by an owner address to a spender address on any supported EVM chain at a specified block

Looks up the status of an Aptos blockchain transaction by its hash on mainnet or testnet

Decodes a raw EVM event log into human-readable fields using a provided ABI and log topics/data

Computes amortized loan payment schedules given principal, annual rate, and term, returning exact decimal results with configurable rounding for AI agents.

Decodes and interprets an Aptos Move function call — including its arguments and type arguments — into a human-readable, structured representation.

Identifies the type/classification of a smart contract at a given EVM address and block height

Performs precise monetary arithmetic (rounding, addition, subtraction, multiplication, splitting, ratio-based splitting) on currency amounts using exact decimal math

Looks up the confirmation status of a blockchain transaction by hash on EVM chains or Aptos

Calculates the price impact percentage of a token swap given input amount and liquidity pool reserves, accounting for swap fees.

Returns current gas price estimates for a specified EVM or Aptos chain at one or more confidence levels

Computes the minimum output or maximum input token amount for a DeFi swap given a trade amount and slippage tolerance in basis points

Forecasts upcoming gas prices on EVM-compatible blockchain networks to help agents optimize transaction timing and cost.

Returns a snapshot of blockchain data at specified confidence levels (1–99) across EVM and Aptos chains, enabling agents to retrieve on-chain state at varying finality thresholds.
