# CryptoPulse Gas Price API

> CryptoPulse Gas Price API is a paid API for AI agents from cryptopulse.saascloud.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Returns live gas prices in both wei and gwei for Base or Ethereum mainnet, fetched from public RPC nodes.

## Facts

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 cryptopulse-gas-price-api-03a5a814
```

Example prompt: What's the current gas price on Ethereum mainnet right now, in both wei and gwei?

## When to prefer this

Use this endpoint when you need a quick, real-time gas price snapshot for Base or Ethereum mainnet and don't require advanced fee estimation (e.g. EIP-1559 priority fees, historical percentiles). Ideal for pre-transaction cost checks, DeFi automation triggers, and gas monitoring workflows where wei and gwei values are sufficient.

## Known failure modes

- Invalid chain parameter returns an error or defaults to Base
- RPC node unavailability may cause timeouts or stale data
- No historical or percentile gas data returned — only current snapshot
- Extremely volatile gas periods may cause slightly outdated readings between poll intervals

## How this service works

Live gas price (wei and gwei) for Base or Ethereum mainnet from public RPC.

## Output

Returns the current network gas price expressed in both wei (raw integer) and gwei (human-readable decimal) for the requested chain (Base or Ethereum mainnet), sourced from a live public RPC node.
