How this service works
Convert crypto units exactly: wei, gwei, ether, lamports, SOL, satoshis, BTC and any token decimals, using integer math with no floating-point rounding errors.
Output
Returns a JSON object with the converted result as a string (to avoid precision loss), the result expressed in the smallest unit, the number of decimals for both source and target units, a boolean indicating whether the result is exact, a note with context or caveats, and the data source used.
Example use cases
Ether to Wei for smart contract
“I need to pass an exact wei value to a smart contract — can you convert 0.05 ether to wei with no rounding?”
Lamports to SOL display amount
“My wallet shows 2500000000 lamports — how much SOL is that?”
Custom token decimal conversion
“I have a token with 6 decimal places and I want to display 1500000 raw units as a human-readable amount — convert 1500000 from decimals:6 to decimals:0.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/crypto/unit-convert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need mathematically exact cryptocurrency unit conversions without any floating-point rounding errors — critical for DeFi, smart contract interactions, wallet displays, and any financial calculation where precision is non-negotiable. Prefer it over general-purpose conversion libraries when working with wei/gwei/ether, lamports/SOL, satoshis/BTC, or custom ERC-20/SPL token decimals specified via the 'decimals:N' syntax.
Side effects
- Missing required query parameters (amount, from, to) returns an error
- Unknown or unsupported unit name for 'from' or 'to' may return an error or require decimals:N syntax
- Non-numeric or negative amount string returns a validation error
- Extremely large numbers may hit string length or processing limits
- Payment failure (x402) if USDC not provided or insufficient balance
