## 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 the-stall-gas-prices-1e4104c6
```

Example prompt: What are the current gas prices on Ethereum — give me the low, medium, and high fee tiers so I can decide when to send my transaction?

## When to prefer this

Choose this endpoint when you need current gas price estimates for blockchain transactions without setting up an API key or account, and you can pay $0.005 USDC per call via x402 on Base mainnet. Ideal for AI agents that need real-time fee data for transaction planning in a permissionless, pay-per-use model.

## Known failure modes

- Network not supported — returns error if requested chain is not available
- Payment failure — USDC payment on Base mainnet not processed, returns 402
- Stale data — gas prices may lag real-time conditions by a few seconds to minutes
- Malformed input — invalid property filter returns empty or error response

## How this service works

Current gas prices and EIP-1559 fee recommendations across 6 major EVM chains: Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain. Returns base fee, priority fee percentiles (slow/standard/fast), and estimated ETH/MATIC/BNB cost for a standard 21k-gas transfer. All sourced from free public RPC endpoints — no API key needed. Use before sending on-chain transactions, estimating agent operating costs, or comparing chain fees for routing decisions.

## Output

Returns current gas price data for a blockchain network, likely including fee tiers (slow/standard/fast or low/medium/high) expressed in gwei or similar units, enabling the caller to estimate transaction costs.
