## 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 cryptointel-gas-prices-47a52e58
```

Example prompt: What are the current gas prices across Ethereum, Base, Polygon, Arbitrum, and Optimism right now?

## When to prefer this

Use this endpoint when you need a multi-chain gas price snapshot in a single call rather than querying individual chain RPCs. Ideal for DeFi agents deciding which network to route a transaction on, or for dashboards displaying current network costs across the major EVM L1/L2 ecosystem.

## Known failure modes

- Upstream RPC provider downtime causing stale or missing gas data
- Network-specific outage returning partial results for some chains
- Payment failure (402) if USDC balance is insufficient
- Rate limiting if called too frequently
- Occasional latency spikes if on-chain data providers are congested

## How this service works
