# Swift Bot Labs EVM Unit Converter

> 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

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability swift-bot-labs-evm-unit-converter-b8b16a58
```

Example prompt: Convert 1.5 ether to gwei — I need the exact wei and gwei values so I can use them in a smart contract call.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
