## 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 amanchain-evm-gas-price-feed-31a3020d -d '<json body>'
```

Example prompt: What are the current gas prices on Ethereum and Base right now — give me both in gwei and USD so I can decide whether to submit my transaction.

## When to prefer this

Choose this endpoint when you need real-time EVM gas prices for Base or Ethereum without requiring an API key or account — it is billed per call via x402 USDC micropayment, making it suitable for infrequent or agent-driven lookups. Prefer it over general crypto data aggregators when you specifically need gwei and USD gas cost data from an on-chain node rather than an off-chain oracle.

## Known failure modes

- Invalid or missing serviceId returns an error response
- Malformed JSON request body causes a 400-level error
- x402 payment failure or insufficient USDC balance prevents the call from completing
- Network or node connectivity issues may cause timeouts or 5xx errors
- Stale data if the AmanChain node is momentarily out of sync with the chain tip

## How this service works

Live gas price on Base and Ethereum in gwei with USD conversion; gas fee API. Deterministic on-chain execution by the AmanChain node — live consensus state, real blocks, pools and balances. Pay per call via x402 (USDC on Base), no account, no API key. POST JSON {"serviceId":"aman-gas-price","request":"<input>"}.

## Output

Returns the current gas price for Base and Ethereum networks expressed in gwei and USD equivalent, sourced from live consensus state and real block/pool data by the AmanChain node.
