x402
Ethereum Unit Converter (wei / gwei / ether / token) is a paid API for AI agents from twin.unykorn.org, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Converts a numeric amount between Ethereum denomination units — wei, gwei, ether, and arbitrary ERC-20 token units with configurable decimals

How this service works
Convert between wei, gwei, ether and token units — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object indicating success, the conversion type ('eth-units'), a payment receipt with transaction hash, USD amount, and receipt ID, plus a generated_at ISO 8601 timestamp. The primary conversion output is confirmed by the 'ok: true' field along with the converted values embedded in the response.
Example use cases
Display ETH balance in readable form
“I'm getting a wallet balance back as 2350000000000000000 wei — can you convert that to ether so I can show it to the user properly?”
Normalize USDC token amount for DeFi calc
“I have a raw USDC token amount of 5000000 and USDC has 6 decimals — convert that to a human-readable number for me.”
Compute gas cost in gwei from wei
“The gas fee came back as 420000000000 wei — what is that in gwei so I can display it as a gas price?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/eth-units?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, paid microservice to convert between Ethereum denominations (wei, gwei, ether) or arbitrary ERC-20 token units without running local BigNumber math. It is especially useful in agent pipelines that already use x402 micropayment infrastructure and need a reliable, hosted conversion step. Prefer it over writing custom BigNumber logic when precision and correctness are critical and a $0.001 per-call cost is acceptable.
Side effects
- Invalid or unrecognized 'from' unit string returns an error response
- Non-numeric or malformed 'amount' string causes a parse failure
- Negative or non-integer 'decimals' value (below 0) is rejected by schema validation
- Missing required params object may return a 400-style error
- Payment failure or insufficient USDC balance blocks the request before conversion runs
