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. human-readable token amount in target unit, decimal or hex integer), or the EIP-55 checksummed Ethereum address string, depending on which operation (units/hex/checksum) was requested.
Example use cases
Gas fee in readable ether
“I'm seeing a gas estimate of 21000 gwei on this transaction — can you convert that to ether so I know what I'm actually paying?”
Hex to decimal block number
“The API returned a block number as 0x11e5a1f — can you turn that into a regular integer for me?”
USDC raw units to dollars
“I got a raw USDC balance of 4750000 from the contract, and USDC uses 6 decimals — what's that in human-readable dollars?”

Endpoint
GEThttps://webtools402.176-109-107-191.sslip.io/crypto/convertWhen to prefer
Use this endpoint when you need precise, on-demand Ethereum unit conversions (wei/gwei/ether or custom decimal token units), hex-to-int or int-to-hex conversion, or need to compute or validate an EIP-55 checksummed Ethereum address — especially within a web3 or blockchain agent workflow where accuracy and standardized formatting matter.
Side effects
- Missing required 'op' query parameter returns an error
- Invalid or unsupported unit name for op=units returns an error
- Malformed or non-Ethereum address for op=checksum returns an error
- Non-numeric or malformed value for op=hex or op=units returns an error
- Payment not provided or insufficient returns HTTP 402
