Swift Bot Labs EVM Unit Converter
x402
Swift Bot Labs EVM Unit Converter is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).
Converts EVM token amounts between wei, gwei, ether, and arbitrary decimal units

How this service works
62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.
Output
A JSON object with fields: ok (boolean), tool name, and a result object containing the original value, from unit, to unit, and the converted result as a string.
Example use cases
Gas price unit conversion
“I need to convert 25 gwei to wei so I can set the exact gas price in my transaction — can you do that conversion?”
Token balance display formatting
“Convert 1500000000000000000 wei to ether so I can show the human-readable balance to my users.”
DeFi amount normalization
“I have a token with 6 decimals and the raw amount is 5000000 — convert that using 6 as the from unit to ether so I know the actual token value.”
Technical details
Endpoint
GEThttps://x402-toolbox.swiftbotlab.workers.dev/v1/evm/units?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, deterministic EVM unit conversion (wei ↔ gwei ↔ ether or custom decimal places) without setting up an account or API key — ideal for AI agents that pay per call with USDC via x402 and need quick on-the-fly blockchain amount normalization.
Side effects
- Missing required 'value' query parameter returns an error
- Invalid unit type for 'from' or 'to' (not wei/gwei/ether/integer decimals) returns a validation error
- Non-numeric value string causes a parsing error
- Payment failure via x402 protocol blocks the request
