# Tx Value Wei to ETH Converter

> Tx Value Wei to ETH 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 raw transaction value field (in wei) to its ether equivalent for human-readable display, using local deterministic math with no RPC or external calls.

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 tx-value-wei-to-eth-converter-1d9bd2a1 -d '<json body>'
```

Example prompt: Can you convert this raw transaction value — 1500000000000000000 wei — into ETH so I can display it properly in the UI?

## When to prefer this

Choose this endpoint when you need a fast, dependency-free, offline wei-to-ETH unit conversion from a raw transaction value field — particularly when you do not have RPC access, want deterministic output without live feeds, and are summarizing or displaying raw tx objects. Not suitable when you need live USD price conversion or on-chain data fetching.

## Known failure modes

- Missing or malformed 'wei' field in request body returns an error response
- Non-numeric string for wei value may cause a parsing or validation error
- Extremely large wei values may hit numeric precision limits
- Payment failure via x402 protocol prevents execution

## How this service works

Convert a transaction value wei field into ether for display. Call when summarizing transfers from raw tx objects without RPC. Returns eth amount from wei value 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 deterministic JSON object containing the ETH equivalent of the supplied wei value, computed entirely with local arithmetic — no RPC, no live price feed, no external dependencies.
