# Vextorium Gas Prices – BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic, Unichain

> Vextorium Gas Prices – BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic, Unichain is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-20).

Returns the current gas price (in Gwei), latest block number, native coin name, and cost of a simple native transfer for seven EVM chains: BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic, and Unichain.

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 vextorium-gas-prices-bnb-chain-avalanche-gnosis-linea-scroll-sonic-faf60763 -d '<json body>'
```

Example prompt: What are the current gas prices and latest block numbers on BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic, and Unichain, and how much would a simple native token transfer cost on each?

## When to prefer this

Use this endpoint when you need real-time gas prices and block heights specifically for BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic, or Unichain expressed in native coin units. For Ethereum, Base, Arbitrum, Optimism, or Polygon with USD-denominated costs, use the companion gas-comparar endpoint on the same host.

## Known failure modes

- Public RPC node unavailable for one or more chains — that chain's entry may be null or missing
- Network congestion causing stale block data
- Upstream publicnode.com outage returning all nulls
- POST body malformed (bodyType mismatch) returning 400 error

## How this service works

Gas price and latest block right now on BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain, with the cost of a simple transfer in native coin.

## Output

A JSON object with an array of entries per chain, each containing: network name (red), latest block number (bloque), native coin ticker (nativo), gas price in Gwei (gas_gwei), and the cost of a 21,000-gas native transfer in native coin (transferencia_nativo). Also includes a source note and a hint to use the gas-comparar endpoint for Ethereum/Base/Arbitrum/Optimism/Polygon with USD costs.
