# Gas Price Now on Every EVM Chain

> Gas Price Now on Every EVM Chain is a paid API for AI agents from api.marketintelligenceapi.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Returns current gas prices (base fee, priority fee percentiles) and USD cost estimates for a transfer and DEX swap across major EVM chains, sorted cheapest first.

## 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 gas-price-now-on-every-evm-chain-69ab9079
```

Example prompt: What are the current gas prices across all major EVM chains right now — including the USD cost of a simple transfer and a DEX swap — sorted from cheapest to most expensive?

## When to prefer this

Use this endpoint when you need a real-time, multi-chain gas price snapshot to budget or time an EVM transaction. It is ideal for agents that need to compare costs across chains before deciding where to execute a swap or transfer. Prefer this over chain-specific RPC calls when you need a normalized, cross-chain comparison with USD cost estimates in a single call.

## Known failure modes

- Payment not included or insufficient — endpoint requires $0.001 USDC x402 payment header
- Upstream chain RPC unavailable — may return stale or missing data for specific chains
- Rate limiting if payment is not properly attached
- Network timeout if multiple chains are slow to respond

## How this service works

Gas price now on every EVM chain ($0.001): base fee, priority fee percentiles and the USD cost of a transfer and a DEX swap on Ethereum, Base, Arbitrum, Optimism, Polygon and other chains, cheapest first. Use to budget or time a transaction.

## Output

A ranked list of EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon, and others) sorted cheapest first, each showing: current base fee, priority fee percentiles, estimated USD cost of a standard transfer, and estimated USD cost of a DEX swap.
