# Gwei to Wei Converter

> Gwei to Wei Converter is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Converts a gas price value from gwei to its equivalent wei integer string for use in EVM transaction builders and eth_gasPrice-style fields.

## 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 gwei-to-wei-converter-8218044f -d '<json body>'
```

Example prompt: Convert 25 gwei to wei so I can use it in my EVM transaction builder as the gas price field.

## When to prefer this

Choose this endpoint when you already have a gas price expressed in gwei and need a precise, correctly-formatted wei integer string for use in EVM transaction builders, eth_gasPrice RPC fields, or on-chain gas budget checks — especially when you want a deterministic, local-math result with no RPC dependency, no API key, and no live market data.

## Known failure modes

- Missing or non-numeric gwei input returns a validation error
- Negative or zero gwei values may return an error or unexpected result
- Payment failure via x402 prevents the conversion from executing
- Extremely large gwei values may exceed integer precision bounds

## How this service works

Convert gas prices from gwei into wei integer strings for EVM transactions. Call when you hold gas price in gwei and need wei for eth_gasPrice-style fields or tx builders. Returns wei as a decimal integer string plus input gwei as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

Returns a JSON object containing the input gwei value echoed back and the equivalent wei expressed as a decimal integer string (e.g. 25 gwei → "25000000000"), enabling direct use in EVM transaction fields without further formatting.
