PayAI Crypto Unit Converter & Address Checksum
x402
PayAI Crypto Unit Converter & Address Checksum is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Converts Ethereum token units (wei/gwei/ether or arbitrary decimal precision), converts between hex and integer representations, and computes or validates EIP-55 checksummed Ethereum addresses.

How this service works
Convert token units (wei/gwei/ether or arbitrary decimals), between hex and int, and compute/validate an EIP-55 checksummed address.
Output
Returns the converted value (e.g. amount in target unit), or for hex/int conversions the equivalent representation, or for checksum operations the EIP-55 checksummed Ethereum address and a validity flag.
Example use cases
Validate user-submitted wallet addresses
“I need to check if someone sent me an Ethereum address that looks suspicious. Can you validate whether this address has the correct EIP-55 checksum and make sure it's a valid format?”
Calculate transaction gas fees in readable units
“A user is about to send a transaction and wants to know how much 250000 gwei is in actual ether so they understand the cost.”
Handle token transfer decimal conversions
“I'm processing a USDC transfer that shows an amount of 5000000 in the blockchain data. Can you convert that to the actual token amount using 6 decimals so I can display it correctly to the user?”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/crypto/convertWhen to prefer
Use this endpoint when an AI agent needs to perform Ethereum-specific unit conversions (wei/gwei/ether or arbitrary ERC-20 decimals), hex-to-int or int-to-hex numeric transformations, or needs to compute or validate an EIP-55 checksummed address — tasks that are frequently needed in blockchain transaction workflows without requiring a full Ethereum node or Web3 library.
Side effects
- Missing required 'op' query parameter returns an error
- Invalid 'op' value outside enum (units/checksum/hex) returns an error
- For op=units, missing 'from', 'to', or 'value' returns an error
- For op=checksum, missing or malformed 'address' parameter returns an error
- For op=hex, missing 'value' returns an error
- Non-numeric value where a number is expected causes a parse error
- Payment not provided or insufficient (x402 payment required)
